Instead it is set based upon whether the node actually can retransmit any messages. 4) some workaround code was removed that was necessary to make the system work when #3 was incorrect 5) the my_install_seq and my_aru fields are compared based upon a window instead of static comparison because it could be that the my_aru is 0xFFFFFF5 where my_install_seq is 5. In this case (after a lot of messages are sent) the comparison would return the incorrect result in the recovery phase of the algorithm. 6) The queue chosen for adding messages to the retransmission queue is now set based upon the encapsulated bit rather then the current state of the state machine. 7) the encapsulated bit is set properly in an endian conversion operation for a multicast message header. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1447 fd59a12c-fef9-0310-b244-a6a79926bd2f + +2007-09-11 Steven Dake + + Add missing files from the ais utils exporting patch. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1445 fd59a12c-fef9-0310-b244-a6a79926bd2f + +2007-09-09 Steven Dake + + Calculate the default path based on the project value of PREFIX + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1444 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Ensure DESTDIR and PREFIX are properly used in Makefiles + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1443 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Expose utils to the user + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1442 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Now that -l is set correclt yuse #include instead of using quotes. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1441 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Static libraries become out of date on Darwin once they are copied or moved + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1440 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Use makefile loops where possible + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1439 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Provide information as to why a plugin refused to load + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1438 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Add extra brackets to clarify scope. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1437 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Fix build dependencies + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1436 fd59a12c-fef9-0310-b244-a6a79926bd2f + + If iface_ver0_p is not reset, then as long as the first plugin loads then all subsequent plugins will report success. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1435 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Missing stdlib.h from lcr_ifact.c. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1434 fd59a12c-fef9-0310-b244-a6a79926bd2f + + HZ not always defined on all Linux systems. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1433 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Patch to allow CFLAGS and LDFLAGS modifications to take effect + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1432 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Logsys testing system. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1431 fd59a12c-fef9-0310-b244-a6a79926bd2f + + Fixes for the logsys system. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1430 fd59a12c-fef9-0310-b244-a6a79926bd2f + + The man page for the logsys logging system. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1429 fd59a12c-fef9-0310-b244-a6a79926bd2f + + The logsys logging system.

object tree traversal preserves relations when syncing - Ordered lists of SUs and SIs - Constructors/destructor per class - Serializers/deserializers per class - Config-change changes sync state - Sync callbacks executes the sync - "Use case" tracing for sync using the SYNCTRACE macro (trace6) - Sync master is initially the winner of a timeout race and if the master leaves the cluster, the node with the lowest node ID becomes new master. - amf_malloc implements an AMF central malloc routine with error handling. + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1200

The problem would occur when I would kill aisexec while my program was running (using EVT and CLM apis). My program is multi-threaded where 1 thread is calling evtDispatch and other threads can be calling evtPublish at various times. The problem I ran into is when I killed aisexec, the evtDispatch would take a lock, but never give it back. At the same time, my sending thread would call evtPublish which would take the lock and hang since evtDispatch never gave up the lock it took. + The fix was to add a few unlocks in evt.c where they appeared to be missing. + Here is the info: + + 1) line 504 in evt.c (lib dir) calls + + pthread_mutex_unlock(&evti->ei_mutex); + goto error_unlock; + + 2) There are subsequent calls to goto error_unlock in later error statements + that do not unlock the mutex before the goto call - the lines are 534 and 541 + + Adding the unlock right before the goto @ 534 and @ 541 fixes the deadlock + for my scenario. + + Kristen Smith + Nortel Networks + + (Logical change 1.110) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@394 fd59a12c-fef9-0310-b244-a6a79926bd2f + +2004-11-29 Steven Dake + + Improve code coverage by testing a few more APIs in the AMF. + (Logical change 1.109) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@393 fd59a12c-fef9-0310-b244-a6a79926bd2f + + testamf.c: Improve code coverage by testing a few more APIs in the AMF. + BKrev: 41ab821fPmG01mXBZYuPJWKuOLHj5A + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@392 fd59a12c-fef9-0310-b244-a6a79926bd2f + +2004-11-25 Steven Dake + + code coverage work cleanup + (Logical change 1.108) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@391 fd59a12c-fef9-0310-b244-a6a79926bd2f + + fix double ;; which causes gcc 2.95 to fail to compile + (Logical change 1.108) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@390 fd59a12c-fef9-0310-b244-a6a79926bd2f + + testparse.c: code coverage work cleanup evt.c: fix double ;; which causes gcc 2.95 to fail to compile + BKrev: 41a51dc9RLGeGsr9z5GLjSGzFovoKQ + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@389 fd59a12c-fef9-0310-b244-a6a79926bd2f + + correct stack corruption when logging data. + (Logical change 1.107) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@388 fd59a12c-fef9-0310-b244-a6a79926bd2f + + remove extra printf from gmi. + (Logical change 1.107) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@387 fd59a12c-fef9-0310-b244-a6a79926bd2f + + parse.c: correct stack corruption when logging data. gmi.c: remove extra printf from gmi. + BKrev: 41a51930u36bUFf2s34EDiXBXWb-1Q + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@386 fd59a12c-fef9-0310-b244-a6a79926bd2f + +2004-11-24 Steven Dake + + Fix compile with gcc 2.95. + (Logical change 1.106) + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@385 fd59a12c-fef9-0310-b244-a6a79926bd2f + + gmi.c, amf.c: Fix compile with gcc 2.95. + BKrev: 41a50bf5bDdOboBSLlLamrDIChW6LQ + + + git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@384 fd59a12c-fef9-0310-b244-a6a79926bd2f + +2004-11-12 Steven Dake + + evs.c: Kristen Smith reported a bug where evs would return 0.0.0.0 in the source address.

All keys in this prefix are read only. +It's only useful for getting a list of loaded services. + +.TP +logging.* +Values read from the configuration file. It's possible to change them at runtime. +If subsystem specific configuration is needed, the key must be in the form +logging.logger_subsys.SERVICE.key, where SERVICE is upper case name of the service and +key is same as in the configuration file. All values are of string type. + +.TP +nodelist.* +Values are read from the configuration file only (dynamic updates are not allowed). +Each node element in the configuration file gets +assigned its position starting from zero. So the first node from the config file has +nodelist.node.0. prefix. To be a valid entry, each node must have +.B ring0_addr +key. +To change the +.B nodeid +key, use a u32 data type. + +Local node position is stored in +.B local_node_pos +key (RO), so it's easy to find +out nodeid/ring addresses of the local node directly from cmap. + +.TP +runtime.blackbox.* +Trigger keys for storing fplay data. It's recommended that you use the corosync-blackbox command +to change keys in this prefix. + +.TP +runtime.force_gather +Set to 'yes' to force the processor to move into the GATHER state. This operation +is dangerous and is not recommended. + +.TP +runtime.config.* +Contains the values actually in use by the totem membership protocol. +Values here are either taken from the Corosync configuration file, +defaults or computed from entries in the config file. For information +on individual keys please refer to the man page +.BR corosync.conf (5). + +.TP +runtime.services.* +Prefix with statistics for service engines. Each service has its own +.B service_id +key in the prefix with the name runtime.services.SERVICE., where SERVICE is the lower case +name of the service. Inside the service prefix is the number of messages received and sent +by the corosync engine in the format runtime.services.SERVICE.EXEC_CALL.rx and +runtime.services.SERVICE.EXEC_CALL.tx, where EXEC_CALL is the internal id of the service +call (so for example 3 in cpg service is receive of multicast message from other +nodes). + +.TP +runtime.totem.members.* +Prefix containing members of the totem single ring protocol. Each member +keys has format runtime.totem.members.NODEID.KEY, where key is +one of: + +.B config_version +Config version of the member node. + +.TP +resources.process.PID.* +Prefix created by applications using SAM with CMAP integration. +It contains the following keys: + +.B recovery +Recovery policy of the process. Can be one of quit or restart. + +.B poll_period +Value passed in sam_initialize as a time_interval. + +.B last_updated +Last time SAM received a heartbeat from the client. + +.B state +State of the client. Can be one of failed, stopped, running and waiting for quorum. + +.TP +uidgid.* +Information about users/groups which are allowed to make IPC connections to +corosync. Entries loaded from configuration file are stored with +uidgid.config.* prefix and are pruned on configuration file reload. Dynamic +entries has uidgid.* prefix and a configuration file reload doesn't affect them. + +.TP +quorum.cancel_wait_for_all +Tells votequorum to cancel waiting for all nodes at cluster startup. Can be used +to unblock quorum if notes are known to be down. For pcs use only. + +.TP +cfg.shutdown_timeout +Sets the timeout within which daemons that are registered for cfg callbacks must respond +to a corosync_cfg_try_shutdown() request. the default is 5000 mS + +.TP +config.reload_in_progress +This value will be set to 1 (or created) when a corosync.conf reload is started, +and set to 0 when the reload is completed. This allows interested subsystems +to do atomic reconfiguration rather than changing each key. Note that +individual add/change/delete notifications will still be sent during a reload. + +.TP +config.totemconfig_reload_in_progress +This key is similar to +.B config.totemconfig_reload_in_progress +but changed after the totem config trigger is processed. It is useful (mainly) +for situations when +.B nodelist.local_node_pos +must be correctly reinstated before anything else. + +.SH STATS KEYS +These keys are in the stats map. All keys in this map are read-only. +Modification tracking of individual keys is supported in the stats map, but not +prefixes. Add/Delete operations are supported on prefixes though so you can track +for new ipc connections or knet interfaces. +.TP +stats.srp.* +Prefix containing statistics about totem. +Typical key prefixes: + +.B commit_entered +Number of times the processor entered COMMIT state. + +.B commit_token_lost +Number of times the processor lost token in COMMIT state. + +.B consensus_timeouts +How many times the processor timed out forming a consensus about membership. + +.B continuous_gather +How many times the processor was not able to reach consensus. + +.B firewall_enabled_or_nic_failure +Set to 1 when processor was not able to reach consensus for long time. The usual +reason is a badly configured firewall or connection failure. + +.B gather_entered +Number of times the processor entered GATHER state. + +.B gather_token_lost +Number of times the processor lost token in GATHER state. + +.B mcast_retx +Number of retransmitted messages. + +.B mcast_rx +Number of received multicast messages. + +.B mcast_tx +Number of transmitted multicast messages. + +.B memb_commit_token_rx +Number of received commit tokens. + +.B memb_commit_token_tx +Number of transmitted commit tokens. + +.B memb_join_rx +Number of received join messages. + +.B memb_join_tx +Number of transmitted join messages. + +.B memb_merge_detect_rx +Number of received member merge messages. + +.B memb_merge_detect_tx +Number of transmitted member merge messages. + +.B orf_token_rx +Number of received orf tokens. + +.B orf_token_tx +Number of transmitted orf tokens. + +.B recovery_entered +Number of times the processor entered recovery. + +.B recovery_token_lost +Number of times the token was lost in recovery state. + +.B rx_msg_dropped +Number of received messages which were dropped because they were not expected +(as example multicast message in commit state). + +.B token_hold_cancel_rx +Number of received token hold cancel messages. + +.B token_hold_cancel_tx +Number of transmitted token hold cancel messages. + +.B mtt_rx_token +Mean transit time of token in milliseconds.

It then provides a +command-line interface to add (up) or remove (down) nodes, and cause network splits and +rejoins. After each event it shows the new quorum status for all nodes. + +Nodes in vqsim are always referred to by their nodeid (the IP address is meaningless) and +optionally by a 'partition' which precedes the nodeid with a colon. By default all nodes +are in partition 0. Nodes can be moved between partitions using the split and join commands. +Multiple nodes can be split and joined at the same time. + +To script vqsim you must send input to it via a pipe rather than just redirecting STDIN. This +is because it runs asynchronously to enable the virtual 'nodes' to report status when needed. +(eg if you kill a subprocess using the 'kill(1)' command it gets removed from the cluster). + +By default vqsim will wait for all nodes in all partitions to reach the same +ring sequence number before returning a prompt, +there is a timeout associated with this in case of a 'node' failure and exceeding this timeout +can (optionally) quit the program signalling an error. + +You can disable waiting using the 'sync off' command or the -n command-line option. This can easily +cause unexpected behaviour so use it with care. + +The number of votes per node is read from corosync.conf. New nodes added using the 'up' command +will copy their number of votes from the first node in corosync.conf. This may not be what you +expect and I might fix it in future.

Empty lines and lines starting with +# character are ignored. The configuration file consists of bracketed top level +directives. The possible directive choices are: + +.TP +totem { } +This top level directive contains configuration options for the totem protocol. +.TP +logging { } +This top level directive contains configuration options for logging. +.TP +quorum { } +This top level directive contains configuration options for quorum. +.TP +nodelist { } +This top level directive contains configuration options for nodes in cluster. +.TP +system { } +This top level directive contains configuration options related to system. +.TP +resources { } +This top level directive contains configuration options for resources. +.TP +nozzle { } +This top level directive contains configuration options for a libnozzle device. + +.PP +The +.B interface sub-directive of totem is optional for UDP and knet transports. + +For knet, multiple interface subsections define parameters for each knet link on the +system. + +For UDPU an interface section is not needed and it is recommended that the nodelist +is used to define cluster nodes. + +.TP +linknumber +This specifies the link number for the interface. When using the knet +protocol, each interface should specify separate link numbers to uniquely +identify to the membership protocol which interface to use for which link. +The linknumber must start at 0. For UDP the only supported linknumber is 0. + +.TP +knet_link_priority +This specifies the priority for the link when knet is used in 'passive' +mode. (see link_mode below) + +.TP +knet_ping_interval +This specifies the interval between knet link pings. +knet_ping_interval and knet_ping_timeout +are a pair, if one is specified the other should be too, otherwise one will be calculated from +the token timeout and one will be taken from the config file. +(default is token timeout / (knet_pong_count*2)) + +.TP +knet_ping_timeout +If no ping is received within this time, the knet link is declared dead. +knet_ping_interval and knet_ping_timeout +are a pair, if one is specified the other should be too, otherwise one will be calculated from +the token timeout and one will be taken from the config file. +(default is token timeout / knet_pong_count) + +.TP +knet_ping_precision +How many values of latency are used to calculate +the average link latency. (default 2048 samples) + +.TP +knet_pong_count +How many valid ping/pongs before a link is marked UP. (default 2) +.TP + +knet_transport +Which IP transport knet should use. valid values are "sctp" or "udp". (default: udp) + +.TP +bindnetaddr (udp only) +This specifies the network address the corosync executive should bind +to when using udp. + +bindnetaddr (udp only) +should be an IP address configured on the system, or a network +address. + +For example, if the local interface is 192.168.5.92 with netmask +255.255.255.0, you should set bindnetaddr to 192.168.5.92 or 192.168.5.0. +If the local interface is 192.168.5.92 with netmask 255.255.255.192, +set bindnetaddr to 192.168.5.92 or 192.168.5.64, and so forth. + +This may also be an IPV6 address, in which case IPV6 networking will be used. +In this case, the exact address must be specified and there is no automatic +selection of the network interface within a specific subnet as with IPv4. + +If IPv6 networking is used, the nodeid field in nodelist must be specified. + +.TP +broadcast (udp only) +This is optional and can be set to yes. If it is set to yes, the broadcast +address will be used for communication. If this option is set, mcastaddr +should not be set. + +.TP +mcastaddr (udp only) +This is the multicast address used by corosync executive. The default +should work for most networks, but the network administrator should be queried +about a multicast address to use. Avoid 224.x.x.x because this is a "config" +multicast address. + +This may also be an IPV6 multicast address, in which case IPV6 networking +will be used. If IPv6 networking is used, the nodeid field in nodelist must +be specified. + +It's not necessary to use this option if cluster_name option is used. If both options +are used, mcastaddr has higher priority. + +.TP +mcastport (udp only) +This specifies the UDP port number. It is possible to use the same multicast +address on a network with the corosync services configured for different +UDP ports. +Please note corosync uses two UDP ports mcastport (for mcast receives) and +mcastport - 1 (for mcast sends). +If you have multiple clusters on the same network using the same mcastaddr +please configure the mcastports with a gap. + +.TP +ttl (udp only) +This specifies the Time To Live (TTL). If you run your cluster on a routed +network then the default of "1" will be too small. This option provides +a way to increase this up to 255. The valid range is 0..255. + +.PP +.PP +Within the +.B totem +directive, there are seven configuration options of which one is required, +five are optional, and one is required when IPV6 is configured in the interface +subdirective. The required directive controls the version of the totem +configuration. The optional option unless using IPV6 directive controls +identification of the processor. The optional options control secrecy and +authentication, the network mode of operation and maximum network MTU +field. + +.TP +version +This specifies the version of the configuration file. Currently the only +valid version for this directive is 2. + +.TP +clear_node_high_bit +This configuration option is optional and is only relevant when no nodeid is +specified. Some corosync clients require a signed 32 bit nodeid that is greater +than zero however by default corosync uses all 32 bits of the IPv4 address space +when generating a nodeid. Set this option to yes to force the high bit to be +zero and therefore ensure the nodeid is a positive signed 32 bit integer. + +WARNING: Cluster behavior is undefined if this option is enabled on only +a subset of the cluster (for example during a rolling upgrade). + +.TP +crypto_model +This specifies which cryptographic library should be used by knet. +Supported values depend on the libknet build and on the installed +cryptography libraries. Typically nss and openssl will be available +but gcrypt and others could also be allowed. + +The default is nss. + +.TP +crypto_hash +This specifies which HMAC authentication should be used to authenticate all +messages. Valid values are none (no authentication), md5, sha1, sha256, +sha384 and sha512. Encrypted transmission is only supported for +the knet transport. + +The default is none. + +.TP +crypto_cipher +This specifies which cipher should be used to encrypt all messages. +Valid values are none (no encryption), aes256, aes192 and aes128. +Enabling crypto_cipher, requires also enabling of crypto_hash. Encrypted +transmission is only supported for the knet transport. + +The default is none. + +.TP +secauth +This implies crypto_cipher=aes256 and crypto_hash=sha256, unless those options +are explicitly set. Encrypted transmission is only supported for the knet +transport. + +The default is off. + +.TP +keyfile +This specifies the fully qualified path to the shared key used to +authenticate and encrypt data used within the Totem protocol. + +The default is /etc/corosync/authkey. + +.TP +key +Shared key stored in configuration instead of authkey file. This option +has lower precedence than keyfile option so it's +used only when keyfile is not specified. +Using this option is not recommended for security reasons. + +.TP +link_mode +This specifies the Kronosnet mode, which may be passive, active, or +rr (round-robin). +.B passive: +the active link with the highest priority (highest number) will be used. If one or more +links share the same priority the one with the lowest link ID will +be used. +.B active: +All active links will be used simultaneously to send traffic. +link priority is ignored. +.B rr: +Round-Robin policy. Each packet will be sent to the next active link in +order. + +If only one interface directive is specified, passive is automatically chosen. + +The maximum number of interface directives that is allowed with Kronosnet +is 8. For other transports it is 1. + +.TP +netmtu +This specifies maximum packet length sent by corosync. It's mainly for the UDPU +(and UDP) transport, where it specifies the network maximum transmit size, but +can be used also with the KNET transport, where it defines the maximum length of packets +passed to the knet layer. To specify the network MTU manually for KNET, use the +.B knet_mtu +option. + +For UDPU (and UDP), setting this value beyond 1500, the regular frame MTU, +requires ethernet devices that support large, or +also called jumbo, frames. If any device in the network doesn't support large +frames, the protocol will not operate properly. The hosts must also have their +mtu size set from 1500 to whatever frame size is specified here. + +Please note while some NICs or switches claim large frame support, they support +9000 MTU as the maximum frame size including the IP header. Setting the netmtu +and host MTUs to 9000 will cause totem to use the full 9000 bytes of the frame. +Then Linux will add a 18 byte header moving the full frame size to 9018. As a +result some hardware will not operate properly with this size of data. A netmtu +of 8982 seems to work for the few large frame devices that have been tested. +Some manufacturers claim large frame support when in fact they support frame +sizes of 4500 bytes. + +When sending multicast traffic, if the network frequently reconfigures, chances are +that some device in the network doesn't support large frames. + +Choose hardware carefully if intending to use large frame support. + +The default is 1500 for UDPU (and UDP) and 65536 for the KNET transport. + +.TP +transport +This directive controls the transport mechanism used. +The default is knet. The transport type can also be set to udpu or udp. +Only knet allows crypto or multiple interfaces per node. + +.TP +cluster_name +This specifies the name of cluster and it's used for automatic generating +of multicast address. + +.TP +config_version +This specifies version of config file. This is converted to unsigned 64-bit int. +By default it's 0. Option is used to prevent joining old nodes with not +up-to-date configuration. If value is not 0, and node is going for first time +(only for first time, join after split doesn't follow this rules) +from single-node membership to multiple nodes membership, other nodes +config_versions are collected. If current node config_version is not +equal to highest of collected versions, corosync is terminated. + +.TP +ip_version +This specifies version of IP to ask DNS resolver for. +The value can be one of +.B ipv4 +(look only for an IPv4 address) +, +.B ipv6 +(check only IPv6 address) +, +.B ipv4-6 +(look for all address families and use first IPv4 address found in the list if there is such address, +otherwise use first IPv6 address) and +.B ipv6-4 +(look for all address families and use first IPv6 address found in the list if there is such address, +otherwise use first IPv4 address). + +Default (if unspecified) is +.B ipv6-4 +for knet and udpu transports and +.B ipv4 +for udp. + +The knet transport supports IPv4 and IPv6 addresses concurrently, +provided they are consistent on each link. + +Within the +.B totem +directive, there are several configuration options which are used to control +the operation of the protocol. It is generally not recommended to change any +of these values without proper guidance and sufficient testing. Some networks +may require larger values if suffering from frequent reconfigurations. Some +applications may require faster failure detection times which can be achieved +by reducing the token timeout. + +.TP +token +This timeout is used directly or as a base for real token timeout calculation (explained in +.B token_coefficient +section). Token timeout specifies in milliseconds until a token loss is declared after not +receiving a token. This is the time spent detecting a failure of a processor +in the current configuration. Reforming a new configuration takes about 50 +milliseconds in addition to this timeout. + +For real token timeout used by totem it's possible to read cmap value of +.B runtime.config.totem.token +key. + +Be careful to use the same timeout values on each of the nodes in the cluster +or unpredictable results may occur. + +The default is 3000 milliseconds. + +.TP +token_warning +Specifies the interval between warnings that the token has not been received. The +value is a percentage of the token timeout and can be set to 0 to disable +warnings. + +The default is 75%. + +.TP +token_coefficient +This value is used only when +.B nodelist +section is specified and contains at least 3 nodes. If so, real token timeout +is then computed as token + (number_of_nodes - 2) * token_coefficient. +This allows cluster to scale without manually changing token timeout +every time new node is added. This value can be set to 0 resulting +in effective removal of this feature. + +The default is 650 milliseconds. + +.TP +token_retransmit +This timeout specifies in milliseconds after how long before receiving a token +the token is retransmitted. This will be automatically calculated if token +is modified. It is not recommended to alter this value without guidance from +the corosync community. + +The minimum is 30 milliseconds. If not set and error occur, make sure +token / (token_retransmits_before_loss_const + 0.2) is more than 30. + +The default is 238 milliseconds for two nodes cluster. Three or more nodes reference +.B token_coefficient. + +.TP +knet_compression_model +Type of compression used by Kronosnet. Supported values depend on +the libknet build and on the installed compression libraries. Typically zlib and lz4 will be available +but bzip2 and others could also be allowed. The default is 'none'. + +.TP +knet_compression_threshold +Tells knet to NOT compress any packets that are smaller than the value +indicated. Default 100 bytes. + +Set to 0 to reset to the default. +Set to 1 to compress everything. + +.TP +knet_compression_level +Many compression libraries allow tuning of compression parameters. For example +0 or 1 ... 9 are commonly used to determine the level of compression. This value +is passed unmodified to the compression library so it is recommended to consult +the library's documentation for more detailed information. + +.TP +hold +This timeout specifies in milliseconds how long the token should be held by +the representative when the protocol is under low utilization. It is not +recommended to alter this value without guidance from the corosync community. + +The default is 180 milliseconds. + +.TP +token_retransmits_before_loss_const +This value identifies how many token retransmits should be attempted before +forming a new configuration. It is also used for token_retransmit +and hold calculations. + +The default is 4 retransmissions. + +.TP +join +This timeout specifies in milliseconds how long to wait for join messages in +the membership protocol. + +The default is 50 milliseconds. + +.TP +send_join +This timeout specifies in milliseconds an upper range between 0 and send_join +to wait before sending a join message. For configurations with less than +32 nodes, this parameter is not necessary. For larger rings, this parameter +is necessary to ensure the NIC is not overflowed with join messages on +formation of a new ring. A reasonable value for large rings (128 nodes) would +be 80msec. Other timer values must also change if this value is changed. Seek +advice from the corosync mailing list if trying to run larger configurations. + +The default is 0 milliseconds. + +.TP +consensus +This timeout specifies in milliseconds how long to wait for consensus to be +achieved before starting a new round of membership configuration. The minimum +value for consensus must be 1.2 * token. This value will be automatically +calculated at 1.2 * token if the user doesn't specify a consensus value. + +For two node clusters, a consensus larger than the join timeout but less than +token is safe. For three node or larger clusters, consensus should be larger +than token. There is an increasing risk of odd membership changes, which still +guarantee virtual synchrony, as node count grows if consensus is less than +token. + +The default is 3600 milliseconds. + +.TP +merge +This timeout specifies in milliseconds how long to wait before checking for +a partition when no multicast traffic is being sent. If multicast traffic +is being sent, the merge detection happens automatically as a function of +the protocol. + +The default is 200 milliseconds. + +.TP +downcheck +This timeout specifies in milliseconds how long to wait before checking +that a network interface is back up after it has been downed. + +The default is 1000 milliseconds. + +.TP +fail_recv_const +This constant specifies how many rotations of the token without receiving any +of the messages when messages should be received may occur before a new +configuration is formed. + +The default is 2500 failures to receive a message. + +.TP +seqno_unchanged_const +This constant specifies how many rotations of the token without any multicast +traffic should occur before the hold timer is started. + +The default is 30 rotations. + +.TP +heartbeat_failures_allowed +[HeartBeating mechanism] +Configures the optional HeartBeating mechanism for faster failure detection. Keep in +mind that engaging this mechanism in lossy networks could cause faulty loss declaration +as the mechanism relies on the network for heartbeating. + +So as a rule of thumb use this mechanism if you require improved failure in low to +medium utilized networks. + +This constant specifies the number of heartbeat failures the system should tolerate +before declaring heartbeat failure e.g 3. Also if this value is not set or is 0 then the +heartbeat mechanism is not engaged in the system and token rotation is the method +of failure detection + +The default is 0 (disabled). + +.TP +max_network_delay +[HeartBeating mechanism] +This constant specifies in milliseconds the approximate delay that your network takes +to transport one packet from one machine to another. This value is to be set by system +engineers and please don't change if not sure as this effects the failure detection +mechanism using heartbeat. + +The default is 50 milliseconds. + +.TP +window_size +This constant specifies the maximum number of messages that may be sent on one +token rotation. If all processors perform equally well, this value could be +large (300), which would introduce higher latency from origination to delivery +for very large rings. To reduce latency in large rings(16+), the defaults are +a safe compromise. If 1 or more slow processor(s) are present among fast +processors, window_size should be no larger than 256000 / netmtu to avoid +overflow of the kernel receive buffers. The user is notified of this by +the display of a retransmit list in the notification logs. There is no loss +of data, but performance is reduced when these errors occur. + +The default is 50 messages. + +.TP +max_messages +This constant specifies the maximum number of messages that may be sent by one +processor on receipt of the token. The max_messages parameter is limited to +256000 / netmtu to prevent overflow of the kernel transmit buffers. + +The default is 17 messages. + +.TP +miss_count_const +This constant defines the maximum number of times on receipt of a token +a message is checked for retransmission before a retransmission occurs. This +parameter is useful to modify for switches that delay multicast packets +compared to unicast packets. The default setting works well for nearly all +modern switches. + +The default is 5 messages. + +.TP +knet_pmtud_interval +How often the knet PMTUd runs to look for network MTU changes. +Value in seconds, default: 30 + +.TP +knet_mtu +Switch between manual and automatic MTU discovery. A value of 0 means +automatic, other values set a manual MTU. +In a setup with multiple interfaces, please specify +the lowest MTU of the selected interfaces. + +The default value is 0. + +.TP +block_unlisted_ips +Allow UDPU and KNET to drop packets from IP addresses that are not known +(nodes which don't exist in the nodelist) to corosync. +Value is yes or no. + +This feature is mainly to protect against the joining of nodes +with outdated configurations after a cluster split. +Another use case is to allow the atomic merge of two independent clusters. + +Changing the default value is not recommended, the overhead is tiny and +an existing cluster may fail if corosync is started on an unlisted node +with an old configuration. + +The default value is yes. + +.TP +cancel_token_hold_on_retransmit +Allows Corosync to hold token by representative when there is too much +retransmit messages. This allows network to process increased load without +overloading it. Used mechanism is same as described for +.B hold +directive. + +Some deployments may prefer to never hold token when there is +retransmit messages. If so, option should be set to yes. + +The default value is no. + +.PP +Within the +.B logging +directive, there are several configuration options which are all optional. + +.PP +The following 3 options are valid only for the top level logging directive: + +.TP +timestamp +This specifies that a timestamp is placed on all log messages. It can be one +of off (no timestamp), on (second precision timestamp) or +hires (millisecond precision timestamp - only when supported by LibQB). + +The default is hires (or on if hires is not supported). + +.TP +fileline +This specifies that file and line should be printed. + +The default is off. + +.TP +function_name +This specifies that the code function name should be printed. + +The default is off. + +.TP +blackbox +This specifies that blackbox functionality should be enabled. + +The default is on. + +.PP +The following options are valid both for top level logging directive +and they can be overridden in logger_subsys entries. + +.TP +to_stderr +.TP +to_logfile +.TP +to_syslog +These specify the destination of logging output. Any combination of +these options may be specified. Valid options are +.B yes +and +.B no. + +The default is syslog and stderr. + +Please note, if you are using to_logfile and want to rotate the file, use logrotate(8) +with the option +.B +copytruncate. +eg. +.ne 18 +.RS +.nf +.ft CW +/var/log/corosync.log { + missingok + compress + notifempty + daily + rotate 7 + copytruncate +} +.ft +.fi +.RE + +.TP +logfile +If the +.B to_logfile +directive is set to +.B yes +, this option specifies the pathname of the log file. + +No default. + +.TP +logfile_priority +This specifies the logfile priority for this particular subsystem.

This means +it is not possible to filter corosync logged messages based on these metadata +(for example using -u or _SYSTEMD_UNIT=UNIT pattern) and also running +systemctl status doesn't display (all) corosync log messages. +The problem is even worse because journald caches pid for some time +(approx. 5 sec) so initial corosync messages have correct metadata. + +.TP +allow_knet_handle_fallback +If knet handle creation fails using privileged operations, allow fallback to +creating knet handle using unprivileged operations. Defaults to no, meaning +if privileged knet handle creation fails, corosync will refuse to start. + +The knet handle will always be created using privileged operations if possible, +setting this to yes only allows fallback to unprivileged operations.

IPMI watchdogs are particularly +notorious in this regard: read about kipmid_max_busy_us in IPMI.txt in +the Linux kernel documentation. + + +.PP +Within the +.B nozzle +directive it is possible to specify options for a libnozzle device. This is a pseudo +ethernet device that routes network traffic through a channel on the corosync knet network +(NOT cpg or any corosync internal service) to other nodes in the cluster. This allows +applications to take advantage of knet features such as multipathing, automatic failover, +link switching etc. Note that libnozzle is not a reliable transport, but you can tunnel TCP +through it for reliable communications. +.br +libnozzle also supports optional interface up/down scripts that are kept under a +/etc/corosync/updown.d/ directory. See the knet documentation for more information. +.br +Only one nozzle device is allowed. +.br +The nozzle stanza takes several options: +.TP +name +The name of the network device to be created. On Linux this may be any name at all, other +platforms have restrictions on the name. +.TP +ipaddr +The IP address (IPv6 or IPv4) of the interface. The bottom part of this address will be replaced +by the local node's nodeid in conjunction with ipprefix. so, eg +ipaddr: 192.168.1.0 +ipprefix: 24 +will make nodeids 1,2,5 use IP addresses 192.168.1.1, 192.168.1.2 & 192.168.1.5. +If a prefix length of 16 is used then the bottom two bytes will be filled in with nodeid numbers. +IPv6 addresses must end in '::', the nodeid will be added after the two colons to make the +local IP address. +Only one IP address is currently supported in the corosync.conf file. Additional IP addresses +can be added in the ifup script if necessary. +.TP +ipprefix +specifies the IP address prefix for the nozzle device (see above) +.TP +macaddr +Specifies the MAC address prefix for the nozzle device. As for the IP address, the bottom part +of the MAC address will be filled in with the node id. In this case no prefix applies, the bottom +two bytes of the MAC address will always be overwritten with the node id. So specifying +macaddr: 54:54:12:24:12:12 on nodeid 1 will result in it having a MAC address of 54:54:12:24:00:01 + +.SH "TO ADD A NEW NODE TO THE CLUSTER" +For example to add a node with address 10.24.38.108 with nodeid 3.

You may then start corosync on the NEW node +and it should join the cluster. If this doesn't work as expected then check the communications between all +three nodes is working, and check the syslog files on all nodes for more information. It's important to note +that the key bit of information about a node failing to join might be on a different node than you expect. + +.SH "TO REMOVE A NODE FROM THE CLUSTER" +This is the reverse procedure to 'Adding a node' above.

Faults in other components of the system have gone unsolved until +Corosync. Corosync is designed for applications to replicate their state to +up to 16 processors. The processors all contain a replica of the application +state. + +The corosync project provides a group message API called CPG. +The project developers recommend CPG be used for most applications. The CPG +service implements a closed group messaging model presenting extended virtual +synchrony guarantees. + +To manage conditions where the process executing the CPG application exchange +fails, we provide the Simple Availability Manager (sam) to provide simple +application restart. + +.SH QUICKSTART +The corosync executive must be configured. In the directory conf in the +source distribution are several files that must be copied to the /etc/corosync +directory. If corosync is packaged by a distro, this may be complete. + +The directory contains the file corosync.conf. Please read the corosync.conf(5) +man page for details on the configuration options. The corosync project will +work out of the box with the default configuration options, although the +administrator may desire different options. + +The corosync executive uses cryptographic techniques to ensure authenticity +and privacy of the messages. In order for corosync to be secure and operate, +a private key must be generated and shared to all processors. + +First generate the key on one of the nodes: + +.nf +unix# corosync-keygen +Corosync Cluster Engine Authentication key generator. +Gathering 2048 bits for key from /dev/urandom. +Writing corosync key to /etc/corosync/authkey. +.fi + +After this operation, a private key will be in the file /etc/corosync/authkey. +This private key must be copied to every processor in the cluster. If the +private key isn't the same for every node, those nodes with nonmatching private +keys will not be able to join the same configuration. + +Copy the key to some security transportable storage or use ssh to transmit the +key from node to node. Then install the key with the command: + +unix#: install -D --group=0 --owner=0 --mode=0400 /path_to_authkey/authkey /etc/corosync/authkey + +If a message "Invalid digest" appears from the corosync executive, the keys +are not consistent between processors. + +Finally run the corosync executive. If corosync is packaged from a distro, it +may be set to start on system start. It may also be turned off by default in +which case the init script for corosync must be enabled. + +.SH USING LIBRARIES +The corosync libraries have header files which must be included in the +developer's application. Once the header file is included, the developer can +reference the corosync interfaces. + +The corosync project recommends that distros place include files in +/usr/include/corosync. + +.SH IPv6 +The corosync project supports both IPv4 and IPv6 network addresses. When using +knet as the transport each link should have the same IP family, but different links +can have different families (eg link 0 could be all IPv4, and link 1 all IPv6). +When using UDP/UDPU the single link should use the same family on all nodes. + +To configure a host for IPv6, use the ifconfig program to add interfaces: +box20: ifconfig eth0 add fec0::1:a800:4ff:fe00:20/64 +box30: ifconfig eth0 add fec0::1:a800:4ff:fe00:30/64 + +If the /64 is not specified, a route for the IPv6 network will not be configured +which will cause significant problems. Make sure a route is available for +IPv6 traffic. + +.SH ARCHITECTURE +The corosync libraries are a thin IPC interface to the corosync executive. The +corosync executive implements the functionality of the corosync APIs for +distributed computing. + +The corosync executive uses the Totem extended virtual synchrony protocol. The +advantage to the end user is excellent performance characteristics and a proven +protocol with excellent reliability. This protocol connects the processors +in a configuration together so they may communicate. + +.SH SECURITY +The corosync executive optionally encrypts and signs all messages sent +over the network. For more details see +.B crypto_model, +.B crypto_hash +and +.B crypto_cipher +options in the +.BR corosync.conf (5). + +If membership messages can be captured by intruders, it is possible to execute +a denial of service attack on the cluster. In this scenario, the cluster is +likely already compromised and a DoS attack is the least of the administration's +worries. + +The security in corosync does not offer perfect forward secrecy because the keys +are reused. It may be possible for an intruder to determine the shared key by +capturing packets in an automated fashion. No such automated attack has +been published as of yet.

This duplicate process copy contains the logic +for executing the SAM server. The SAM server is responsible for requesting +healthchecks from the active process, and controlling the lifecycle of the +active process when it fails. If the active process fails to respond to the +healthcheck request sent by the SAM server, it will be sent a user configurable +signal (default SIGTERM) to request shutdown of the application. After a configured time interval, the +process will be forcibly killed by being sent a SIGKILL signal. Once the +active process terminates, the SAM server will create a new active process. + +.P +The Simple Availability Manager is meant to be used in conjunction with the +cpg service. Used together, it is possible to restart a cpg process that fails +healthchecking during operation. + +.P +The main features of SAM include: + +.RS +.IP \(bu 3 +A configurable recovery policy. +.IP \(bu 3 +A configurable time interval for health check operations. +.IP \(bu 3 +A notification via signal before recovery action is taken. +.IP \(bu 3 +A mechanism to indicate to the application the number of times an active +process has been created by the SAM server. +.IP \(bu 3 +Both application driven health checking and event driven health checking. +.RE + +.SH Initializing SAM +.P +The SAM library is initialized by \fBsam_initialize(3)\fR. +\fBsam_initalize(3)\fR may only be called once per process. Calling it more +then once has undefined results and is not recommended or tested. + +.SH Setting warning callback +.P +User configurable signal (default \fISIGTERM\fR) is sent to the application when a recovery action is +planned. The application can use the \fBsignal(3)\fR system call to monitor +for this signal. + +.P +There are no special constraints on what SAM apis may be called in a warning +callback. After \fItime_interval\fR expires, a SIGKILL signal is sent to the +active process to force its termination. + +.SH Registering the active process +.P +The active process is registered with SAM by calling \fBsam_register(3)\fR. +This function should only be called one time in a process. After a recovery +action is taken, the new active process will begin execution at the next line +of code in a user process after \fBsam_register(3)\fR. + +.SH Enabling event driven healthchecking +.P +Two types of healthchecking are available to the user. The first model is one +where the user application healthchecks during its normal operation. It is +never requested to healtcheck, and if the active process doesn't respond within +the time interval, the process will be restarted. + +.P +A more useful mechanism for healthchecking is event driven healthchecking. +Because this model is directed by the SAM server, It isn't necessary to guess +or add timers to the active process to signal a healthcheck operation is +successful. To use event driven healthchecking, +the \fBsam_hc_callback_register(3)\fR function should be executed. + +.SH Quorum integration +.P +SAM has special policies (\fISAM_RECOVERY_POLICY_QUIT\fR and \fISAM_RECOVERY_POLICY_RESTART\fR) +for integration with quorum service. This policies changes SAM behaviour in two aspects. +.RS +.IP \(bu 3 +Call of \fBsam_start(3)\fR blocks until corosync becomes quorate +.IP \(bu 3 +User selected recovery action is taken immediately after lost of quorum. +.RE + +.SH Storing user data +.P +Sometimes there is need to store some data, which survives between instances. +One can in such case use files, databases, ... or much simpler in memory solution +presented by \fBsam_data_store(3)\fR, \fBsam_data_restore(3)\fR and \fBsam_data_getsize(3)\fR +functions. + +.SH Confdb integration +.P +SAM has policy flag used for confdb system integration (\fISAM_RECOVERY_POLICY_CONFDB\fR). +If process is registered with this flag, new confdb object PROCESS_NAME:PID is created with following +keys: +.RS +.IP \(bu 3 +\fIrecovery\fR - will be quit or restart depending on policy +.IP \(bu 3 +\fIpoll_period\fR - period of health checking in milliseconds +.IP \(bu 3 +\fIlast_updated\fR - Timestamp (in nanoseconds) of the last health check. +.IP \(bu 3 +\fIstate\fR - state of process (can be one of registered, started, failed, waiting for quorum) +.RE + +.P +Object is automatically deleted if process exits with stopped health checking. + +.P +Confdb integration with corosync watchdog can be used in implicit and explicit way. + +.P +Implicit way is achieved by setting recovery policy to QUIT and let process exit with started health checking. +If this happened, object is not deleted and corosync watchdog will take required action. + +.P +Explicit way is useful for situations, when developer can deal with some non-fatal fall of application. +This mode is achieved by setting policy to RESTART and using SAM same as without Confdb integration. +If real fail is needed (like too many restarts at all, per/sec, ...), it's possible to use \fBsam_mark_failed(3)\fR +and let corosync watchdog take required action. + +.SH BUGS +.SH "SEE ALSO" +.BR sam_initialize (3), +.BR sam_data_getsize (3), +.BR sam_data_restore (3), +.BR sam_data_store (3), +.BR sam_finalize (3), +.BR sam_mark_failed (3), +.BR sam_start (3), +.BR sam_stop (3), +.BR sam_register (3), +.BR sam_warn_signal_set (3), +.BR sam_hc_send (3), +.BR sam_hc_callback_register (3) diff --git a/man/sam_register.3.in b/man/sam_register.3.in new file mode 100644 index 0000000..2af86d2 --- /dev/null +++ b/man/sam_register.3.in @@ -0,0 +1,88 @@ +.\"/* +.\" * Copyright (c) 2009 Red Hat, Inc. +.\" * +.\" * All rights reserved. +.\" * +.\" * Author: Jan Friesse (jfriesse@redhat.com) +.\" * +.\" * This software licensed under BSD license, the text of which follows: +.\" * +.\" * Redistribution and use in source and binary forms, with or without +.\" * modification, are permitted provided that the following conditions are met: +.\" * +.\" * - Redistributions of source code must retain the above copyright notice, +.\" * this list of conditions and the following disclaimer. +.\" * - Redistributions in binary form must reproduce the above copyright notice, +.\" * this list of conditions and the following disclaimer in the documentation +.\" * and/or other materials provided with the distribution. +.\" * - Neither the name of the Red Hat, Inc. nor the names of its +.\" * contributors may be used to endorse or promote products derived from this +.\" * software without specific prior written permission. +.\" * +.\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" +.\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE +.\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE +.\" * ARE DISCLAIMED.

This service can be optionally loaded +into the nodes of a corosync cluster to avoid split-brain situations. +It does this by having a number of votes assigned to each system in the cluster and ensuring +that only when a majority of the votes are present, cluster operations are allowed to proceed. +The service must be loaded into all nodes or none. If it is loaded into a subset of cluster nodes +the results will be unpredictable. +.PP +The following corosync.conf extract will enable votequorum service within corosync: +.PP +.nf +quorum { + provider: corosync_votequorum +} +.fi +.PP +votequorum reads its configuration from corosync.conf. Some values can be changed at runtime, others +are only read at corosync startup. It is very important that those values are consistent +across all the nodes participating in the cluster or votequorum behavior will be unpredictable. +.PP +votequorum requires an expected_votes value to function, this can be provided in two ways. +The number of expected votes will be automatically calculated when the nodelist { } section is +present in corosync.conf or expected_votes can be specified in the quorum { } section. Lack of +both will disable votequorum. If both are present at the same time, +the quorum.expected_votes value will override the one calculated from the nodelist. +.PP +Example (no nodelist) of an 8 node cluster (each node has 1 vote): +.nf + +quorum { + provider: corosync_votequorum + expected_votes: 8 +} +.fi +.PP +Example (with nodelist) of a 3 node cluster (each node has 1 vote): +.nf + +quorum { + provider: corosync_votequorum +} + +nodelist { + node { + ring0_addr: 192.168.1.1 + } + node { + ring0_addr: 192.168.1.2 + } + node { + ring0_addr: 192.168.1.3 + } +} +.fi +.SH SPECIAL FEATURES +.PP +.B two_node: 1 +.PP +Enables two node cluster operations (default: 0). +.PP +The "two node cluster" is a use case that requires special consideration. +With a standard two node cluster, each node with a single vote, there +are 2 votes in the cluster. Using the simple majority calculation +(50% of the votes + 1) to calculate quorum, the quorum would be 2. +This means that the both nodes would always have +to be alive for the cluster to be quorate and operate. +.PP +Enabling two_node: 1, quorum is set artificially to 1. +.PP +Example configuration 1: + +.nf +quorum { + provider: corosync_votequorum + expected_votes: 2 + two_node: 1 +} +.fi + +.PP +Example configuration 2: + +.nf +quorum { + provider: corosync_votequorum + two_node: 1 +} + +nodelist { + node { + ring0_addr: 192.168.1.1 + } + node { + ring0_addr: 192.168.1.2 + } +} +.fi +.PP +NOTES: enabling two_node: 1 automatically enables wait_for_all. It is +still possible to override wait_for_all by explicitly setting it to 0. +If more than 2 nodes join the cluster, the two_node option is +automatically disabled. +.PP +.B wait_for_all: 1 +.PP +Enables Wait For All (WFA) feature (default: 0). +.PP +The general behaviour of votequorum is to switch a cluster from inquorate to quorate +as soon as possible. For example, in an 8 node cluster, where every node has 1 vote, +expected_votes is set to 8 and quorum is (50% + 1) 5. As soon as 5 (or more) nodes +are visible to each other, the partition of 5 (or more) becomes quorate and can +start operating. +.PP +When WFA is enabled, the cluster will be quorate for the first time +only after all nodes have been visible at least once at the same time. +.PP +This feature has the advantage of avoiding some startup race conditions, with the cost +that all nodes need to be up at the same time at least once before the cluster +can operate. +.PP +A common startup race condition based on the above example is that as soon as 5 +nodes become quorate, with the other 3 still offline, the remaining 3 nodes will +be fenced. +.PP +It is very useful when combined with last_man_standing (see below). +.PP +Example configuration: +.nf + +quorum { + provider: corosync_votequorum + expected_votes: 8 + wait_for_all: 1 +} +.fi +.PP +.B last_man_standing: 1 +/ +.B last_man_standing_window: 10000 +.PP +Enables Last Man Standing (LMS) feature (default: 0). +Tunable last_man_standing_window (default: 10 seconds, expressed in ms). +.PP +The general behaviour of votequorum is to set expected_votes and quorum +at startup (unless modified by the user at runtime, see below) and use +those values during the whole lifetime of the cluster. +.PP +Using for example an 8 node cluster where each node has 1 vote, expected_votes +is set to 8 and quorum to 5. This condition allows a total failure of 3 +nodes. If a 4th node fails, the cluster becomes inquorate and it will +stop providing services. +.PP +Enabling LMS allows the cluster to dynamically recalculate expected_votes +and quorum under specific circumstances. It is essential to enable +WFA when using LMS in High Availability clusters. +.PP +Using the above 8 node cluster example, with LMS enabled the cluster can retain +quorum and continue operating by losing, in a cascade fashion, up to 6 nodes with +only 2 remaining active. +.PP +Example chain of events: +.nf +1) cluster is fully operational with 8 nodes. + (expected_votes: 8 quorum: 5) + +2) 3 nodes die, cluster is quorate with 5 nodes. + +3) after last_man_standing_window timer expires, + expected_votes and quorum are recalculated. + (expected_votes: 5 quorum: 3) + +4) at this point, 2 more nodes can die and + cluster will still be quorate with 3. + +5) once again, after last_man_standing_window + timer expires expected_votes and quorum are + recalculated. + (expected_votes: 3 quorum: 2) + +6) at this point, 1 more node can die and + cluster will still be quorate with 2. + +7) one more last_man_standing_window timer + (expected_votes: 2 quorum: 2) +.fi +.PP +NOTES: In order for the cluster to downgrade automatically from 2 nodes +to a 1 node cluster, the auto_tie_breaker feature must also be enabled (see below). +If auto_tie_breaker is not enabled, and one more failure occurs, the +remaining node will not be quorate. LMS does not work with asymmetric voting +schemes, each node must vote 1. LMS is also incompatible with quorum devices, +if last_man_standing is specified in corosync.conf then the quorum device +will be disabled. + +.PP +Example configuration 1: +.nf + +quorum { + provider: corosync_votequorum + expected_votes: 8 + last_man_standing: 1 +} +.fi +.PP +Example configuration 2 (increase timeout to 20 seconds): +.nf + +quorum { + provider: corosync_votequorum + expected_votes: 8 + last_man_standing: 1 + last_man_standing_window: 20000 +} +.fi +.PP +.B auto_tie_breaker: 1 +.PP +Enables Auto Tie Breaker (ATB) feature (default: 0). +.PP +The general behaviour of votequorum allows a simultaneous node failure up +to 50% - 1 node, assuming each node has 1 vote. +.PP +When ATB is enabled, the cluster can suffer up to 50% of the nodes failing +at the same time, in a deterministic fashion. By default the cluster +partition, or the set of nodes that are still in contact with the +node that has the lowest nodeid will remain quorate. The other nodes will +be inquorate. This behaviour can be changed by also specifying +.PP +.B auto_tie_breaker_node: lowest|highest| +.PP +\(oqlowest\(cq is the default, \(oqhighest\(cq is similar in that if the current set of +nodes contains the highest nodeid then it will remain quorate. Alternatively +it is possible to specify a particular node ID or list of node IDs that will +be required to maintain quorum. If a (space-separated) list is given, the +nodes are evaluated in order, so if the first node is present then it will +be used to determine the quorate partition, if that node is not in either +half (ie was not in the cluster before the split) then the second node ID +will be checked for and so on. ATB is incompatible with quorum devices - +if auto_tie_breaker is specified in corosync.conf then the quorum device +will be disabled. +.PP +Example configuration 1: +.nf + +quorum { + provider: corosync_votequorum + expected_votes: 8 + auto_tie_breaker: 1 + auto_tie_breaker_node: lowest +} +.fi +.PP +Example configuration 2: +.nf +quorum { + provider: corosync_votequorum + expected_votes: 8 + auto_tie_breaker: 1 + auto_tie_breaker_node: 1 3 5 +} +.PP +.fi +.PP +.B allow_downscale: 1 +.PP +Enables allow downscale (AD) feature (default: 0). +.PP +THIS FEATURE IS INCOMPLETE AND CURRENTLY UNSUPPORTED. +.PP +The general behaviour of votequorum is to never decrease expected votes or quorum. +.PP +When AD is enabled, both expected votes and quorum are recalculated when +a node leaves the cluster in a clean state (normal corosync shutdown process) down +to configured expected_votes. +.PP +Example use case: +.PP +.nf +1) N node cluster (where N is any value higher than 3) + +2) expected_votes set to 3 in corosync.conf + +3) only 3 nodes are running + +4) admin requires to increase processing power and adds 10 nodes + +5) internal expected_votes is automatically set to 13 + +6) minimum expected_votes is 3 (from configuration) + +- up to this point this is standard votequorum behavior - + +7) once the work is done, admin wants to remove nodes from the cluster + +8) using an ordered shutdown the admin can reduce the cluster size + automatically back to 3, but not below 3, where normal quorum + operation will work as usual. + +.fi +.PP +Example configuration: +.nf + +quorum { + provider: corosync_votequorum + expected_votes: 3 + allow_downscale: 1 +} +.fi +allow_downscale implicitly enabled EVT (see below). +.PP +.B expected_votes_tracking: 1 +.PP +Enables Expected Votes Tracking (EVT) feature (default: 0). +.PP +Expected Votes Tracking stores the highest-seen value of expected votes on disk and uses +that as the minimum value for expected votes in the absence of any higher authority (eg +a current quorate cluster). This is useful for when a group of nodes becomes detached from +the main cluster and after a restart could have enough votes to provide quorum, which can +happen after using allow_downscale. +.PP +Note that even if the in-memory version of expected_votes is reduced, eg by removing nodes +or using corosync-quorumtool, the stored value will still be the highest value seen - it +never gets reduced. +.PP +The value is held in the file ev_tracking (stored in the directory configured in system.state_dir +or /var/lib/corosync/ when unset) which can be deleted if you +really do need to reduce the expected votes for any reason, like the node has been moved +to a different cluster. +.PP +.fi +.PP +.SH VARIOUS NOTES +.PP +* WFA / LMS / ATB / AD can be used combined together. +.PP +* In order to change the default votes for a node there are two options: +.nf + +1) nodelist: + +nodelist { + node { + ring0_addr: 192.168.1.1 + quorum_votes: 3 + } + .... +} + +2) quorum section (deprecated): + +quorum { + provider: corosync_votequorum + expected_votes: 2 + votes: 2 +} + +.fi +In the event that both nodelist and quorum { votes: } are defined, the value +from the nodelist will be used. +.PP +* Only votes, quorum_votes, expected_votes and two_node can be changed at runtime.

It is the external interface to +the vote-based quorum service. This service is optionally loaded into all nodes in a corosync cluster +to avoid split-brain situations. It does this by having a number of votes assigned to each system +in the cluster and ensuring that only when a majority of the votes are present, cluster operations are +allowed to proceed. +.PP +The library provides a mechanism to: +.PP +* Query the quorum status +.PP +* Get a list of nodes known to the quorum service +.PP +* Receive notifications of quorum state changes +.PP +* Change the number of votes assigned to a node +.PP +* Change the number of expected votes for a cluster to be quorate +.PP +* Connect an additional quorum device to allow small clusters to remain quorate during node outages. +.PP +.SH VIRTUAL SYNCHRONY +Votequorum is the only one service where communication with library is allowed during synchronization +phase. This makes it possible for quorum device to react to membership change and decide to vote or +not without timing hazard, because corosync stands in synchronization phase until qdevice on all +nodes votes or timeout expires. + +As a side effect, extended virtual synchrony is broken for the votequorum service. This means, that +messages sent during synchronization phase can be delivered sooner then messages sent right +before sync phase began. This applies also for local messages. +.SH BUGS +No known bugs at the time of writing. The authors are from outerspace.
