It fixes a performance +regression in librbd, an important CRUSH misbehavior (see below), and +several RGW bugs. We have also backported support for flock/fcntl +locks to ceph-fuse and libcephfs. + +We recommend that all Firefly users upgrade. + +For more detailed information, see :download:`the complete changelog <../changelog/v0.80.9.txt>`. + +Adjusting CRUSH maps +-------------------- + +* This point release fixes several issues with CRUSH that trigger + excessive data migration when adjusting OSD weights. These are most + obvious when a very small weight change (e.g., a change from 0 to + .01) triggers a large amount of movement, but the same set of bugs + can also lead to excessive (though less noticeable) movement in + other cases. + + However, because the bug may already have affected your cluster, + fixing it may trigger movement *back* to the more correct location. + For this reason, you must manually opt-in to the fixed behavior. + + In order to set the new tunable to correct the behavior:: + + ceph osd crush set-tunable straw_calc_version 1 + + Note that this change will have no immediate effect. However, from + this point forward, any 'straw' bucket in your CRUSH map that is + adjusted will get non-buggy internal weights, and that transition + may trigger some rebalancing. + + You can estimate how much rebalancing will eventually be necessary + on your cluster with:: + + ceph osd getcrushmap -o /tmp/cm + crushtool -i /tmp/cm --num-rep 3 --test --show-mappings > /tmp/a 2>&1 + crushtool -i /tmp/cm --set-straw-calc-version 1 -o /tmp/cm2 + crushtool -i /tmp/cm2 --reweight -o /tmp/cm2 + crushtool -i /tmp/cm2 --num-rep 3 --test --show-mappings > /tmp/b 2>&1 + wc -l /tmp/a # num total mappings + diff -u /tmp/a /tmp/b | grep -c ^+ # num changed mappings + + Divide the number of changed lines by the total number of lines in + /tmp/a.

+=============== + +This Firefly point release fixes an potential data corruption problem +when ceph-osd daemons run on top of XFS and service Firefly librbd +clients. A recently added allocation hint that RBD utilizes triggers +an XFS bug on some kernels (Linux 3.2, and likely others) that leads +to data corruption and deep-scrub errors (and inconsistent PGs). This +release avoids the situation by disabling the allocation hint until we +can validate which kernels are affected and/or are known to be safe to +use the hint on. + +We recommend that all v0.80.x Firefly users urgently upgrade, +especially if they are using RBD. + +Notable Changes +--------------- + +* osd: disable XFS extsize hint by default (#8830, Samuel Just) +* rgw: fix extra data pool default name (Yehuda Sadeh) + +For more detailed information, see :download:`the complete changelog <../changelog/v0.80.4.txt>`. + + +v0.80.3 Firefly +=============== + +This is the third Firefly point release.

It contains a range of +important fixes, including several bugs in the OSD cache tiering, some +compatibility checks that affect upgrade situations, several radosgw +bugs, and an irritating and unnecessary feature bit check that +prevents older clients from communicating with a cluster with any +erasure coded pools. + +One someone large change in this point release is that the ceph RPM +package is separated into a ceph and ceph-common package, similar to +Debian. The ceph-common package contains just the client libraries +without any of the server-side daemons. + +We recommend that all v0.80.x Firefly users skip this release and use +v0.80.3. + +Notable Changes +--------------- + +* ceph-disk: better debug logging (Alfredo Deza) +* ceph-disk: fix preparation of OSDs with dmcrypt (#6700, Stephen F Taylor) +* ceph-disk: partprobe on prepare to fix dm-crypt (#6966, Eric Eastman) +* do not require ERASURE_CODE feature from clients (#8556, Sage Weil) +* libcephfs-java: build with older JNI headers (Greg Farnum) +* libcephfs-java: fix build with gcj-jdk (Dmitry Smirnov) +* librados: fix osd op tid for redirected ops (#7588, Samuel Just) +* librados: fix rados_pool_list buffer bounds checks (#8447, Sage Weil) +* librados: resend ops when pool overlay changes (#8305, Sage Weil) +* librbd, ceph-fuse: reduce CPU overhead for clean object check in cache (Haomai Wang) +* mon: allow deletion of cephfs pools (John Spray) +* mon: fix default pool ruleset choice (#8373, John Spray) +* mon: fix health summary for mon low disk warning (Sage Weil) +* mon: fix 'osd pool set <pool> cache_target_full_ratio' (Geoffrey Hartz) +* mon: fix quorum feature check (Greg Farnum) +* mon: fix request forwarding in mixed firefly+dumpling clusters 9#8727, Joao Eduardo Luis) +* mon: fix rule vs ruleset check in 'osd pool set ... crush_ruleset' command (John Spray) +* mon: make osd 'down' count accurate (Sage Weil) +* mon: set 'next commit' in primary-affinity reply (Ilya Dryomov) +* mon: verify CRUSH features are supported by all mons (#8738, Greg Farnum) +* msgr: fix sequence negotiation during connection reset (Guang Yang) +* osd: block scrub on blocked objects (#8011, Samuel Just) +* osd: call XFS hint ioctl less often (#8241, Ilya Dryomov) +* osd: copy xattr spill out marker on clone (Haomai Wang) +* osd: fix flush of snapped objects (#8334, Samuel Just) +* osd: fix hashindex restart of merge operation (#8332, Samuel Just) +* osd: fix osdmap subscription bug causing startup hang (Greg Farnum) +* osd: fix potential null deref (#8328, Sage Weil) +* osd: fix shutdown race (#8319, Sage Weil) +* osd: handle 'none' in CRUSH results properly during peering (#8507, Samuel Just) +* osd: set no spill out marker on new objects (Greg Farnum) +* osd: skip op ordering debug checks on tiered pools (#8380, Sage Weil) +* rados: enforce 'put' alignment (Lluis Pamies-Juarez) +* rest-api: fix for 'rx' commands (Ailing Zhang) +* rgw: calc user manifest etag and fix check (#8169, #8436, Yehuda Sadeh) +* rgw: fetch attrs on multipart completion (#8452, Yehuda Sadeh, Sylvain Munaut) +* rgw: fix buffer overflow for long instance ids (#8608, Yehuda Sadeh) +* rgw: fix entity permission check on metadata put (#8428, Yehuda Sadeh) +* rgw: fix multipart retry race (#8269, Yehuda Sadeh) +* rpm: split ceph into ceph and ceph-common RPMs (Sandon Van Ness, Dan Mick) +* sysvinit: continue startin daemons after failure doing mount (#8554, Sage Weil) + +For more detailed information, see :download:`the complete changelog <../changelog/v0.80.2.txt>`. + +v0.80.1 Firefly +=============== + +This first Firefly point release fixes a few bugs, the most visible +being a problem that prevents scrub from completing in some cases. + +Notable Changes +--------------- + +* osd: revert incomplete scrub fix (Samuel Just) +* rgw: fix stripe calculation for manifest objects (Yehuda Sadeh) +* rgw: improve handling, memory usage for abort reads (Yehuda Sadeh) +* rgw: send Swift user manifest HTTP header (Yehuda Sadeh) +* libcephfs, ceph-fuse: expose MDS session state via admin socket (Yan, Zheng) +* osd: add simple throttle for snap trimming (Sage Weil) +* monclient: fix possible hang from ill-timed monitor connection failure (Sage Weil) +* osd: fix trimming of past HitSets (Sage Weil) +* osd: fix whiteouts for non-writeback cache modes (Sage Weil) +* osd: prevent divide by zero in tiering agent (David Zafman) +* osd: prevent busy loop when tiering agent can do no work (David Zafman) + +For more detailed information, see :download:`the complete changelog <../changelog/v0.80.1.txt>`. + + +v0.80 Firefly +============= + +This release will form the basis for our long-term supported release +Firefly, v0.80.x. The big new features are support for erasure coding +and cache tiering, although a broad range of other features, fixes, +and improvements have been made across the code base. Highlights include: + +* *Erasure coding*: support for a broad range of erasure codes for lower + storage overhead and better data durability. +* *Cache tiering*: support for creating 'cache pools' that store hot, + recently accessed objects with automatic demotion of colder data to + a base tier. Typically the cache pool is backed by faster storage + devices like SSDs. +* *Primary affinity*: Ceph now has the ability to skew selection of + OSDs as the "primary" copy, which allows the read workload to be + cheaply skewed away from parts of the cluster without migrating any + data. +* *Key/value OSD backend* (experimental): An alternative storage backend + for Ceph OSD processes that puts all data in a key/value database like + leveldb. This provides better performance for workloads dominated by + key/value operations (like radosgw bucket indices). +* *Standalone radosgw* (experimental): The radosgw process can now run + in a standalone mode without an apache (or similar) web server or + fastcgi. This simplifies deployment and can improve performance. + +We expect to maintain a series of stable releases based on v0.80 +Firefly for as much as a year. In the meantime, development of Ceph +continues with the next release, Giant, which will feature work on the +CephFS distributed file system, more alternative storage backends +(like RocksDB and f2fs), RDMA support, support for pyramid erasure +codes, and additional functionality in the block device (RBD) like +copy-on-read and multisite mirroring. + + +Upgrade Sequencing +------------------ + +* If your existing cluster is running a version older than v0.67 + Dumpling, please first upgrade to the latest Dumpling release before + upgrading to v0.80 Firefly. Please refer to the :ref:`dumpling-upgrade` + documentation. + +* We recommend adding the following to the [mon] section of your + ceph.conf prior to upgrade:: + + mon warn on legacy crush tunables = false + + This will prevent health warnings due to the use of legacy CRUSH + placement. Although it is possible to rebalance existing data + across your cluster (see the upgrade notes below), we do not + normally recommend it for production environments as a large amount + of data will move and there is a significant performance impact from + the rebalancing. + +* Upgrade daemons in the following order: + + #. Monitors + #. OSDs + #. MDSs and/or radosgw + + If the ceph-mds daemon is restarted first, it will wait until all + OSDs have been upgraded before finishing its startup sequence. If + the ceph-mon daemons are not restarted prior to the ceph-osd + daemons, they will not correctly register their new capabilities + with the cluster and new features may not be usable until they are + restarted a second time. + +* Upgrade radosgw daemons together. There is a subtle change in behavior + for multipart uploads that prevents a multipart request that was initiated + with a new radosgw from being completed by an old radosgw. + + +Upgrading from v0.79 +-------------------- + +* OSDMap's json-formatted dump changed for keys 'full' and 'nearfull'. + What was previously being outputted as 'true' or 'false' strings are + now being outputted 'true' and 'false' booleans according to json syntax. + +* HEALTH_WARN on 'mon osd down out interval == 0'. Having this option set + to zero on the leader acts much like having the 'noout' flag set. This + warning will only be reported if the monitor getting the 'health' or + 'status' request has this option set to zero. + +* Monitor 'auth' commands now require the mon 'x' capability. This matches + dumpling v0.67.x and earlier, but differs from emperor v0.72.x. + +* A librados WATCH operation on a non-existent object now returns ENOENT; + previously it did not. + +* Librados interface change: As there are no partial writes, the rados_write() + and rados_append() operations now return 0 on success like rados_write_full() + always has. This includes the C++ interface equivalents and AIO return + values for the aio variants. + +* The radosgw init script (sysvinit) how requires that the 'host = ...' line in + ceph.conf, if present, match the short hostname (the output of 'hostname -s'), + not the fully qualified hostname or the (occasionally non-short) output of + 'hostname'. Failure to adjust this when upgrading from emperor or dumpling + may prevent the radosgw daemon from starting. + +Upgrading from v0.72 Emperor +---------------------------- + +* See notes above. + +* The 'ceph -s' or 'ceph status' command's 'num_in_osds' field in the + JSON and XML output has been changed from a string to an int. + +* The recently added 'ceph mds set allow_new_snaps' command's syntax + has changed slightly; it is now 'ceph mds set allow_new_snaps true'. + The 'unset' command has been removed; instead, set the value to + 'false'. + +* The syntax for allowing snapshots is now 'mds set allow_new_snaps + <true|false>' instead of 'mds <set,unset> allow_new_snaps'. + +* 'rbd ls' on a pool which never held rbd images now exits with code + 0. It outputs nothing in plain format, or an empty list in + non-plain format. This is consistent with the behavior for a pool + which used to hold images, but contains none. Scripts relying on + this behavior should be updated. + +* The MDS requires a new OSD operation TMAP2OMAP, added in this release. When + upgrading, be sure to upgrade and restart the ceph-osd daemons before the + ceph-mds daemon. The MDS will refuse to start if any up OSDs do not support + the new feature. + +* The 'ceph mds set_max_mds N' command is now deprecated in favor of + 'ceph mds set max_mds N'. + +* The 'osd pool create ...' syntax has changed for erasure pools. + +* The default CRUSH rules and layouts are now using the 'bobtail' + tunables and defaults. Upgraded clusters using the old values will + now present with a health WARN state. This can be disabled by + adding 'mon warn on legacy crush tunables = false' to ceph.conf and + restarting the monitors. Alternatively, you can switch to the new + tunables with 'ceph osd crush tunables firefly,' but keep in mind + that this will involve moving a *significant* portion of the data + already stored in the cluster and in a large cluster may take + several days to complete. We do not recommend adjusting tunables on a + production cluster. + +* We now default to the 'bobtail' CRUSH tunable values that are first supported + by Ceph clients in bobtail (v0.56) and Linux kernel version v3.9. If you + plan to access a newly created Ceph cluster with an older kernel client, you + should use 'ceph osd crush tunables legacy' to switch back to the legacy + behavior. Note that making that change will likely result in some data + movement in the system, so adjust the setting before populating the new + cluster with data. + +* We now set the HASHPSPOOL flag on newly created pools (and new + clusters) by default. Support for this flag first appeared in + v0.64; v0.67 Dumpling is the first major release that supports it. + It is first supported by the Linux kernel version v3.9. If you plan + to access a newly created Ceph cluster with an older kernel or + clients (e.g, librados, librbd) from a pre-dumpling Ceph release, + you should add 'osd pool default flag hashpspool = false' to the + '[global]' section of your 'ceph.conf' prior to creating your + monitors (e.g., after 'ceph-deploy new' but before 'ceph-deploy mon + create ...'). + +* The configuration option 'osd pool default crush rule' is deprecated + and replaced with 'osd pool default crush replicated ruleset'. 'osd + pool default crush rule' takes precedence for backward compatibility + and a deprecation warning is displayed when it is used. + +* As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now + receives <arg> as an integer instead of a string. This affects how + 'hashpspool' flag is set/unset: instead of 'true' or 'false', it now + must be '0' or '1'. + +* The behavior of the CRUSH 'indep' choose mode has been changed. No + ceph cluster should have been using this behavior unless someone has + manually extracted a crush map, modified a CRUSH rule to replace + 'firstn' with 'indep', recompiled, and reinjected the new map into + the cluster. If the 'indep' mode is currently in use on a cluster, + the rule should be modified to use 'firstn' instead, and the + administrator should wait until any data movement completes before + upgrading. + +* The 'osd dump' command now dumps pool snaps as an array instead of an + object. + + +Upgrading from v0.67 Dumpling +----------------------------- + +* See notes above. + +* ceph-fuse and radosgw now use the same default values for the admin + socket and log file paths that the other daemons (ceph-osd, + ceph-mon, etc.) do. If you run these daemons as non-root, you may + need to adjust your ceph.conf to disable these options or to adjust + the permissions on /var/run/ceph and /var/log/ceph. + +* The MDS now disallows snapshots by default as they are not + considered stable. The command 'ceph mds set allow_snaps' will + enable them. + +* For clusters that were created before v0.44 (pre-argonaut, Spring + 2012) and store radosgw data, the auto-upgrade from TMAP to OMAP + objects has been disabled. Before upgrading, make sure that any + buckets created on pre-argonaut releases have been modified (e.g., + by PUTing and then DELETEing an object from each bucket). Any + cluster created with argonaut (v0.48) or a later release or not + using radosgw never relied on the automatic conversion and is not + affected by this change. + +* Any direct users of the 'tmap' portion of the librados API should be + aware that the automatic tmap -> omap conversion functionality has + been removed. + +* Most output that used K or KB (e.g., for kilobyte) now uses a + lower-case k to match the official SI convention. Any scripts that + parse output and check for an upper-case K will need to be modified. + +* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async() + don't drop a reference to the completion object on error, caller needs to take + care of that. This has never really worked correctly and we were leaking an + object + +* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the + specified location, as that's a job for 'ceph osd crush add'. It will + however continue to work just the same as long as the osd already exists + in the crush map. + +* The OSD now enforces that class write methods cannot both mutate an + object and return data. The rbd.assign_bid method, the lone + offender, has been removed. This breaks compatibility with + pre-bobtail librbd clients by preventing them from creating new + images. + +* librados now returns on commit instead of ack for synchronous calls. + This is a bit safer in the case where both OSDs and the client crash, and + is probably how it should have been acting from the beginning. Users are + unlikely to notice but it could result in lower performance in some + circumstances. Those who care should switch to using the async interfaces, + which let you specify safety semantics precisely. + +* The C++ librados AioComplete::get_version() method was incorrectly + returning an int (usually 32-bits). To avoid breaking library + compatibility, a get_version64() method is added that returns the + full-width value. The old method is deprecated and will be removed + in a future release. Users of the C++ librados API that make use of + the get_version() method should modify their code to avoid getting a + value that is truncated from 64 to to 32 bits. + + +Notable changes since v0.79

No changes are being made to the code +base at this point except those that fix bugs. Please test this +release if you intend to make use of the new erasure-coded pools or +cache tiers in firefly. + +This release fixes a range of bugs found in v0.78 and streamlines the +user experience when creating erasure-coded pools. There is also a +raft of fixes for the MDS (multi-mds, directory fragmentation, and +large directories). The main notable new piece of functionality is a +small change to allow radosgw to use an erasure-coded pool for object +data. + + +Upgrading +--------- +* Erasure pools created with v0.78 will no longer function with v0.79. You + will need to delete the old pool and create a new one. + +* A bug was fixed in the authentication handshake with big-endian + architectures that prevent authentication between big- and + little-endian machines in the same cluster. If you have a cluster + that consists entirely of big-endian machines, you will need to + upgrade all daemons and clients and restart. + +* The 'ceph.file.layout' and 'ceph.dir.layout' extended attributes are + no longer included in the listxattr(2) results to prevent problems with + 'cp -a' and similar tools. + +* Monitor 'auth' read-only commands now expect the user to have 'rx' caps. + This is the same behavior that was present in dumpling, but in emperor + and more recent development releases the 'r' cap was sufficient. The + affected commands are:: + + ceph auth export + ceph auth get + ceph auth get-key + ceph auth print-key + ceph auth list + +Notable Changes +--------------- +* ceph-conf: stop creating bogus log files (Josh Durgin, Sage Weil) +* common: fix authentication on big-endian architectures (Dan Mick) +* debian: change directory ownership between ceph and ceph-common (Sage Weil) +* init: fix startup ordering/timeout problem with OSDs (Dmitry Smirnov) +* librbd: skip zeroes/holes when copying sparse images (Josh Durgin) +* mds: cope with MDS failure during creation (John Spray) +* mds: fix crash from client sleep/resume (Zheng Yan) +* mds: misc fixes for directory fragments (Zheng Yan) +* mds: misc fixes for larger directories (Zheng Yan) +* mds: misc fixes for multiple MDSs (Zheng Yan) +* mds: remove .ceph directory (John Spray) +* misc coverity fixes, cleanups (Danny Al-Gaaf) +* mon: add erasure profiles and improve erasure pool creation (Loic Dachary) +* mon: 'ceph osd pg-temp ...' and primary-temp commands (Ilya Dryomov) +* mon: fix pool count in 'ceph -s' output (Sage Weil) +* msgr: improve connection error detection between clients and monitors (Greg Farnum, Sage Weil) +* osd: add/fix CPU feature detection for jerasure (Loic Dachary) +* osd: improved scrub checks on clones (Sage Weil, Sam Just) +* osd: many erasure fixes (Sam Just) +* osd: move to jerasure2 library (Loic Dachary) +* osd: new tests for erasure pools (David Zafman) +* osd: reduce scrub lock contention (Guang Yang) +* rgw: allow use of an erasure data pool (Yehuda Sadeh) + + +v0.78 +===== + +This development release includes two key features: erasure coding and +cache tiering. A huge amount of code was merged for this release and +several additional weeks were spent stabilizing the code base, and it +is now in a state where it is ready to be tested by a broader user +base. + +This is *not* the firefly release. Firefly will be delayed for at +least another sprint so that we can get some operational experience +with the new code and do some additional testing before committing to +long term support. + +.. note:: Please note that while it is possible to create and test + erasure coded pools in this release, the pools will not be + usable when you upgrade to v0.79 as the OSDMap encoding will + subtlely change. Please do not populate your test pools + with important data that can't be reloaded. + +Upgrading +--------- + +* Upgrade daemons in the following order: + + #. Monitors + #. OSDs + #. MDSs and/or radosgw + + If the ceph-mds daemon is restarted first, it will wait until all + OSDs have been upgraded before finishing its startup sequence. If + the ceph-mon daemons are not restarted prior to the ceph-osd + daemons, they will not correctly register their new capabilities + with the cluster and new features may not be usable until they are + restarted a second time. + +* Upgrade radosgw daemons together. There is a subtle change in behavior + for multipart uploads that prevents a multipart request that was initiated + with a new radosgw from being completed by an old radosgw. + +* CephFS recently added support for a new 'backtrace' attribute on + file data objects that is used for lookup by inode number (i.e., NFS + reexport and hard links), and will later be used by fsck repair. + This replaces the existing anchor table mechanism that is used for + hard link resolution. In order to completely phase that out, any + inode that has an outdated backtrace attribute will get updated when + the inode itself is modified. This will result in some extra workload + after a legacy CephFS file system is upgraded. + +* The per-op return code in librados' ObjectWriteOperation interface + is now filled in. + +* The librados cmpxattr operation now handles xattrs containing null bytes as + data rather than null-terminated strings. + +* Compound operations in librados that create and then delete the same object + are now explicitly disallowed (they fail with -EINVAL). + +* The default leveldb cache size for the ceph-osd daemon has been + increased from 4 MB to 128 MB. This will increase the memory + footprint of that process but tends to increase performance of omap + (key/value) objects (used for CephFS and the radosgw). If memory in your + deployment is tight, you can preserve the old behavior by adding:: + + leveldb write buffer size = 0 + leveldb cache size = 0 + + to your ceph.conf to get back the (leveldb) defaults. + +Notable Changes +--------------- +* ceph-brag: new client and server tools (Sebastien Han, Babu Shanmugam) +* ceph-disk: use partx on RHEL or CentOS instead of partprobe (Alfredo Deza) +* ceph: fix combination of 'tell' and interactive mode (Joao Eduardo Luis) +* ceph-fuse: fix bugs with inline data and multiple MDSs (Zheng Yan) +* client: fix getcwd() to use new LOOKUPPARENT operation (Zheng Yan) +* common: fall back to json-pretty for admin socket (Loic Dachary) +* common: fix 'config dump' debug prefix (Danny Al-Gaaf) +* common: misc coverity fixes (Danny Al-Gaaf) +* common: throtller, shared_cache performance improvements, TrackedOp (Greg Farnum, Samuel Just) +* crush: fix JSON schema for dump (John Spray) +* crush: misc cleanups, tests (Loic Dachary) +* crush: new vary_r tunable (Sage Weil) +* crush: prevent invalid buckets of type 0 (Sage Weil) +* keyvaluestore: add perfcounters, misc bug fixes (Haomai Wang) +* keyvaluestore: portability improvements (Noah Watkins) +* libcephfs: API changes to better support NFS reexport via Ganesha (Matt Benjamin, Adam Emerson, Andrey Kuznetsov, Casey Bodley, David Zafman) +* librados: API documentation improvements (John Wilkins, Josh Durgin) +* librados: fix object enumeration bugs; allow iterator assignment (Josh Durgin) +* librados: streamline tests (Josh Durgin) +* librados: support for atomic read and omap operations for C API (Josh Durgin) +* librados: support for osd and mon command timeouts (Josh Durgin) +* librbd: pass allocation hints to OSD (Ilya Dryomov) +* logrotate: fix bug that prevented rotation for some daemons (Loic Dachary) +* mds: avoid duplicated discovers during recovery (Zheng Yan) +* mds: fix file lock owner checks (Zheng Yan) +* mds: fix LOOKUPPARENT, new LOOKUPNAME ops for reliable NFS reexport (Zheng Yan) +* mds: fix xattr handling on setxattr (Zheng Yan) +* mds: fix xattrs in getattr replies (Sage Weil) +* mds: force backtrace updates for old inodes on update (Zheng Yan) +* mds: several multi-mds and dirfrag bug fixes (Zheng Yan) +* mon: encode erasure stripe width in pool metadata (Loic Dachary) +* mon: erasure code crush rule creation (Loic Dachary) +* mon: erasure code plugin support (Loic Dachary) +* mon: fix bugs in initial post-mkfs quorum creation (Sage Weil) +* mon: fix error output to terminal during startup (Joao Eduardo Luis) +* mon: fix legacy CRUSH tunables warning (Sage Weil) +* mon: fix osd_epochs lower bound tracking for map trimming (Sage Weil) +* mon: fix OSDMap encoding features (Sage Weil, Aaron Ten Clay) +* mon: fix 'pg dump' JSON output (John Spray) +* mon: include dirty stats in 'ceph df detail' (Sage Weil) +* mon: list quorum member names in quorum order (Sage Weil) +* mon: prevent addition of non-empty cache tier (Sage Weil) +* mon: prevent deletion of CephFS pools (John Spray) +* mon: warn when cache tier approaches 'full' (Sage Weil) +* osd: allocation hint, with XFS support (Ilya Dryomov) +* osd: erasure coded pool support (Samuel Just) +* osd: fix bug causing slow/stalled recovery (#7706) (Samuel Just) +* osd: fix bugs in log merging (Samuel Just) +* osd: fix/clarify end-of-object handling on read (Loic Dachary) +* osd: fix impolite mon session backoff, reconnect behavior (Greg Farnum) +* osd: fix SnapContext cache id bug (Samuel Just) +* osd: increase default leveldb cache size and write buffer (Sage Weil, Dmitry Smirnov) +* osd: limit size of 'osd bench ...' arguments (Joao Eduardo Luis) +* osdmaptool: new --test-map-pgs mode (Sage Weil, Ilya Dryomov) +* osd, mon: add primary-affinity to adjust selection of primaries (Sage Weil) +* osd: new 'status' admin socket command (Sage Weil) +* osd: simple tiering agent (Sage Weil) +* osd: store checksums for erasure coded object stripes (Samuel Just) +* osd: tests for objectstore backends (Haomai Wang) +* osd: various refactoring and bug fixes (Samuel Just, David Zafman) +* rados: add 'set-alloc-hint' command (Ilya Dryomov) +* rbd-fuse: fix enumerate_images overflow, memory leak (Ilya Dryomov) +* rbdmap: fix upstart script (Stephan Renatus) +* rgw: avoid logging system events to usage log (Yehuda Sadeh) +* rgw: fix Swift range reponse (Yehuda Sadeh) +* rgw: improve scalability for manifest objects (Yehuda Sadeh) +* rgw: misc fixes for multipart objects, policies (Yehuda Sadeh) +* rgw: support non-standard MultipartUpload command (Yehuda Sadeh) + + + +v0.77 +===== + +This is the final development release before the Firefly feature +freeze. The main items in this release include some additional +refactoring work in the OSD IO path (include some locking +improvements), per-user quotas for the radosgw, a switch to civetweb +from mongoose for the prototype radosgw standalone mode, and a +prototype leveldb-based backend for the OSD. The C librados API also +got support for atomic write operations (read side transactions will +appear in v0.78). + +Upgrading +--------- + +* The 'ceph -s' or 'ceph status' command's 'num_in_osds' field in the + JSON and XML output has been changed from a string to an int. + +* The recently added 'ceph mds set allow_new_snaps' command's syntax + has changed slightly; it is now 'ceph mds set allow_new_snaps true'. + The 'unset' command has been removed; instead, set the value to + 'false'. + +* The syntax for allowing snapshots is now 'mds set allow_new_snaps + <true|false>' instead of 'mds <set,unset> allow_new_snaps'. + +Notable Changes +--------------- + +* osd: client IO path changes for EC (Samuel Just) +* common: portability changes to support libc++ (Noah Watkins) +* common: switch to unordered_map from hash_map (Noah Watkins) +* rgw: switch from mongoose to civetweb (Yehuda Sadeh) +* osd: improve locking in fd lookup cache (Samuel Just, Greg Farnum) +* doc: many many updates (John Wilkins) +* rgw: user quotas (Yehuda Sadeh) +* mon: persist quorum features to disk (Greg Farnum) +* mon: MForward tests (Loic Dachary) +* mds: inline data support (Li Wang, Yunchuan Wen) +* rgw: fix many-part multipart uploads (Yehuda Sadeh) +* osd: new keyvaluestore-dev backend based on leveldb (Haomai Wang) +* rbd: prevent deletion of images with watchers (Ilya Dryomov) +* osd: avoid touching leveldb for some xattrs (Haomai Wang, Sage Weil) +* mailmap: affiliation updates (Loic Dachary) +* osd: new OSDMap encoding (Greg Farnum) +* osd: generalize scrubbing infrastructure to allow EC (David Zafman) +* rgw: several doc fixes (Alexandre Marangone) +* librados: add C API coverage for atomic write operations (Christian Marie) +* rgw: improve swift temp URL support (Yehuda Sadeh) +* rest-api: do not fail when no OSDs yet exist (Dan Mick) +* common: check preexisting admin socket for active daemon before removing (Loic Dachary) +* osd: handle more whitespace (newline, tab) in osd capabilities (Sage Weil) +* mon: handle more whitespace (newline, tab) in mon capabilities (Sage Weil) +* rgw: make multi-object delete idempotent (Yehuda Sadeh) +* crush: fix off-by-one error in recent refactor (Sage Weil) +* rgw: fix read_user_buckets 'max' behavior (Yehuda Sadeh) +* mon: change mds allow_new_snaps syntax to be more consistent (Sage Weil) + + +v0.76 +===== + +This release includes another batch of updates for firefly +functionality. Most notably, the cache pool infrastructure now +support snapshots, the OSD backfill functionality has been generalized +to include multiple targets (necessary for the coming erasure pools), +and there were performance improvements to the erasure code plugin on +capable processors. The MDS now properly utilizes (and seamlessly +migrates to) the OSD key/value interface (aka omap) for storing directory +objects. There continue to be many other fixes and improvements for +usability and code portability across the tree. + +Upgrading +--------- + +* 'rbd ls' on a pool which never held rbd images now exits with code + 0. It outputs nothing in plain format, or an empty list in + non-plain format. This is consistent with the behavior for a pool + which used to hold images, but contains none. Scripts relying on + this behavior should be updated. + +* The MDS requires a new OSD operation TMAP2OMAP, added in this release. When + upgrading, be sure to upgrade and restart the ceph-osd daemons before the + ceph-mds daemon.

Johnson) +* rgw: prototype mongoose frontend (Yehuda Sadeh) + + + +v0.74 +===== + +This release includes a few substantial pieces for Firefly, including +a long-overdue switch to 3x replication by default and a switch to the +"new" CRUSH tunables by default (supported since bobtail). There is +also a fix for a long-standing radosgw bug (stalled GET) that has +already been backported to emperor and dumpling. + +Upgrading +--------- + +* We now default to the 'bobtail' CRUSH tunable values that are first supported + by Ceph clients in bobtail (v0.56) and Linux kernel version v3.9. If you + plan to access a newly created Ceph cluster with an older kernel client, you + should use 'ceph osd crush tunables legacy' to switch back to the legacy + behavior. Note that making that change will likely result in some data + movement in the system, so adjust the setting before populating the new + cluster with data. + +* We now set the HASHPSPOOL flag on newly created pools (and new + clusters) by default. Support for this flag first appeared in + v0.64; v0.67 Dumpling is the first major release that supports it. + It is first supported by the Linux kernel version v3.9. If you plan + to access a newly created Ceph cluster with an older kernel or + clients (e.g, librados, librbd) from a pre-dumpling Ceph release, + you should add 'osd pool default flag hashpspool = false' to the + '[global]' section of your 'ceph.conf' prior to creating your + monitors (e.g., after 'ceph-deploy new' but before 'ceph-deploy mon + create ...'). + +* The configuration option 'osd pool default crush rule' is deprecated + and replaced with 'osd pool default crush replicated ruleset'. 'osd + pool default crush rule' takes precedence for backward compatibility + and a deprecation warning is displayed when it is used. + +Notable Changes +--------------- + +* buffer: some zero-copy groundwork (Josh Durgin) +* ceph-disk: avoid fd0 (Loic Dachary) +* crush: default to bobtail tunables (Sage Weil) +* crush: many additional tests (Loic Dachary) +* crush: misc fixes, cleanups (Loic Dachary) +* crush: new rule steps to adjust retry attempts (Sage Weil) +* debian: integrate misc fixes from downstream packaging (James Page) +* doc: big update to install docs (John Wilkins) +* libcephfs: fix resource leak (Zheng Yan) +* misc coverity fixes (Xing Lin, Li Wang, Danny Al-Gaaf) +* misc portability fixes (Noah Watkins, Alan Somers) +* mon, osd: new 'erasure' pool type (still not fully supported) +* mon: add 'mon getmap EPOCH' (Joao Eduardo Luis) +* mon: collect misc metadata about osd (os, kernel, etc.), new 'osd metadata' command (Sage Weil) +* osd: default to 3x replication +* osd: do not include backfill targets in acting set (David Zafman) +* osd: new 'chassis' type in default crush hierarchy (Sage Weil) +* osd: requery unfound on stray notify (#6909) (Samuel Just) +* osd: some PGBackend infrastructure (Samuel Just) +* osd: support for new 'memstore' (memory-backed) backend (Sage Weil) +* rgw: fix fastcgi deadlock (do not return data from librados callback) (Yehuda Sadeh) +* rgw: fix reading bucket policy (#6940) +* rgw: fix use-after-free when releasing completion handle (Yehuda Sadeh) + + +v0.73 +===== + +This release, the first development release after emperor, includes +many bug fixes and a few additional pieces of functionality. The +first batch of larger changes will be landing in the next version, +v0.74. + +Upgrading +--------- + +- As part of fix for #6796, 'ceph osd pool set <pool> <var> <arg>' now + receives <arg> as an integer instead of a string. This affects how + 'hashpspool' flag is set/unset: instead of 'true' or 'false', it now + must be '0' or '1'. + +- The behavior of the CRUSH 'indep' choose mode has been changed. No + ceph cluster should have been using this behavior unless someone has + manually extracted a crush map, modified a CRUSH rule to replace + 'firstn' with 'indep', recompiled, and reinjected the new map into + the cluster. If the 'indep' mode is currently in use on a cluster, + the rule should be modified to use 'firstn' instead, and the + administrator should wait until any data movement completes before + upgrading. + +- The 'osd dump' command now dumps pool snaps as an array instead of an + object. + +- The radosgw init script (sysvinit) how requires that the 'host = ...' line in + ceph.conf, if present, match the short hostname (the output of 'hostname -s'), + not the fully qualified hostname or the (occasionally non-short) output of + 'hostname'. Failure to adjust this when upgrading from emperor or dumpling + may prevent the radosgw daemon from starting. + + +Notable Changes +--------------- + +* ceph-crush-location: new hook for setting CRUSH location of osd daemons on start +* ceph-kvstore-tool: expanded command set and capabilities (Joao Eduardo Luis) +* ceph.spec: fix build dependency (Loic Dachary) +* common: fix aligned buffer allocation (Loic Dachary) +* doc: many many install doc improvements (John Wilkins) +* mds: fix readdir end check (Zheng Yan) +* mds: update old-format backtraces opportunistically (Zheng Yan) +* misc cleanups from coverity (Xing Lin) +* misc portability fixes (Noah Watkins, Christophe Courtaut, Alan Somers, huanjun) +* mon: 'osd dump' dumps pool snaps as array, not object (Dan Mick) +* mon: allow debug quorum_{enter,exit} commands via admin socket +* mon: prevent extreme changes in pool pg_num (Greg Farnum) +* mon: take 'osd pool set ...' value as an int, not string (Joao Eduardo Luis) +* mon: trim MDSMaps (Joao Eduardo Luis) +* osd: fix object_info_t encoding bug from emperor (Sam Just) +* rbd: add 'rbdmap' init script for mapping rbd images on book (Adam Twardowski) +* rgw: add 'status' command to sysvinit script (David Moreau Simard) +* rgw: fix error setting empty owner on ACLs (Yehuda Sadeh) +* rgw: optionally defer to bucket ACLs instead of object ACLs (Liam Monahan) +* rgw: support for password (instead of admin token) for keystone authentication (Christophe Courtaut) +* sysvinit, upstart: prevent both init systems from starting the same daemons (Josh Durgin) |
