Highlights for Giant include: + +* *RADOS Performance*: a range of improvements have been made in the + OSD and client-side librados code that improve the throughput on + flash backends and improve parallelism and scaling on fast machines. +* *CephFS*: we have fixed a raft of bugs in CephFS and built some + basic journal recovery and diagnostic tools. Stability and + performance of single-MDS systems is vastly improved in Giant. + Although we do not yet recommend CephFS for production deployments, + we do encourage testing for non-critical workloads so that we can + better gauge the feature, usability, performance, and stability + gaps. +* *Local Recovery Codes*: the OSDs now support an erasure-coding scheme + that stores some additional data blocks to reduce the IO required to + recover from single OSD failures. +* *Degraded vs misplaced*: the Ceph health reports from 'ceph -s' and + related commands now make a distinction between data that is + degraded (there are fewer than the desired number of copies) and + data that is misplaced (stored in the wrong location in the + cluster). The distinction is important because the latter does not + compromise data safety. +* *Tiering improvements*: we have made several improvements to the + cache tiering implementation that improve performance. Most + notably, objects are not promoted into the cache tier by a single + read; they must be found to be sufficiently hot before that happens. +* *Monitor performance*: the monitors now perform writes to the local + data store asynchronously, improving overall responsiveness. +* *Recovery tools*: the ceph_objectstore_tool is greatly expanded to + allow manipulation of an individual OSDs data store for debugging + and repair purposes. This is most heavily used by our QA + infrastructure to exercise recovery code. + +Upgrade Sequencing +------------------ + +* If your existing cluster is running a version older than v0.80.x + Firefly, please first upgrade to the latest Firefly release before + moving on to Giant. We have not tested upgrades directly from + Emperor, Dumpling, or older releases. + + We *have* tested: + + * Firefly to Giant + * Dumpling to Firefly to Giant + +* Please upgrade daemons in the following order: + + #. Monitors + #. OSDs + #. MDSs and/or radosgw + + Note that the relative ordering of OSDs and monitors should not matter, but + we primarily tested upgrading monitors first. + +Upgrading from v0.80x Firefly +----------------------------- + +* The client-side caching for librbd is now enabled by default (rbd + cache = true). A safety option (rbd cache writethrough until flush + = true) is also enabled so that writeback caching is not used until + the library observes a 'flush' command, indicating that the librbd + users is passing that operation through from the guest VM. This + avoids potential data loss when used with older versions of qemu + that do not support flush. + + leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB + leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB + leveldb_block_size = 64*1024 = 65536 // 64KB + leveldb_compression = false + leveldb_log = "" + + OSDs will still maintain the following osd-specific defaults: + + leveldb_log = "" + +* The 'rados getxattr ...' command used to add a gratuitous newline to the attr + value; it now does not. + +* The ``*_kb perf`` counters on the monitor have been removed. These are + replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is + replaced by ``cluster_osd_bytes``). + +* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed + via the ``ceph df detail -f json-pretty`` and related commands) have been + replaced with corresponding ``*_bytes`` fields. Similarly, the + ``total_space``, ``total_used``, and ``total_avail`` fields are replaced with + ``total_bytes``, ``total_used_bytes``, and ``total_avail_bytes`` fields. + +* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes`` + fields were incorrectly reporting ops; this is now fixed. + +* The ``rados df --format=json`` output previously included ``read_kb`` and + ``write_kb`` fields; these have been removed. Please use ``read_bytes`` and + ``write_bytes`` instead (and divide by 1024 if appropriate). + +* The experimental keyvaluestore-dev OSD backend had an on-disk format + change that prevents existing OSD data from being upgraded. This + affects developers and testers only. + +* mon-specific and osd-specific leveldb options have been removed. + From this point onward users should use the `leveldb_*` generic + options and add the options in the appropriate sections of their + configuration files. Monitors will still maintain the following + monitor-specific defaults: + + leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB + leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB + leveldb_block_size = 64*1024 = 65536 // 64KB + leveldb_compression = false + leveldb_log = "" + + OSDs will still maintain the following osd-specific defaults: + + leveldb_log = "" + +* CephFS support for the legacy anchor table has finally been removed. + Users with file systems created before firefly should ensure that inodes + with multiple hard links are modified *prior* to the upgrade to ensure that + the backtraces are written properly. For example:: + + sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \; + +* We disallow nonsensical 'tier cache-mode' transitions. From this point + onward, 'writeback' can only transition to 'forward' and 'forward' + can transition to 1) 'writeback' if there are dirty objects, or 2) any if + there are no dirty objects. + +Notable Changes since v0.86 +--------------------------- + +* ceph-disk: use new udev rules for centos7/rhel7 (#9747 Loic Dachary) +* libcephfs-java: fix fstat mode (Noah Watkins) +* librados: fix deadlock when listing PG contents (Guang Yang) +* librados: misc fixes to the new threading model (#9582 #9706 #9845 #9873 Sage Weil) +* mds: fix inotable initialization (Henry C Chang) +* mds: gracefully handle unknown lock type in flock requests (Yan, Zheng) +* mon: add read-only, read-write, and role-definer rols (Joao Eduardo Luis) +* mon: fix mon cap checks (Joao Eduardo Luis) +* mon: misc fixes for new paxos async writes (#9635 Sage Weil) +* mon: set scrub timestamps on PG creation (#9496 Joao Eduardo Luis) +* osd: erasure code: fix buffer alignment (Janne Grunau, Loic Dachary) +* osd: fix alloc hint induced crashes on mixed clusters (#9419 David Zafman) +* osd: fix backfill reservation release on rejection (#9626, Samuel Just) +* osd: fix ioprio option parsing (#9676 #9677 Loic Dachary) +* osd: fix memory leak during snap trimming (#9113 Samuel Just) +* osd: misc peering and recovery fixes (#9614 #9696 #9731 #9718 #9821 #9875 Samuel Just, Guang Yang) + +Notable Changes since v0.80.x Firefly +------------------------------------- + +* bash completion improvements (Wido den Hollander) +* brag: fixes, improvements (Loic Dachary) +* buffer: improve rebuild_page_aligned (Ma Jianpeng) +* build: fix build on alpha (Michael Cree, Dmitry Smirnov) +* build: fix CentOS 5 (Gerben Meijer) +* build: fix yasm check for x32 (Daniel Schepler, Sage Weil) +* ceph-brag: add tox tests (Alfredo Deza) +* ceph-conf: flush log on exit (Sage Weil) +* ceph.conf: update sample (Sebastien Han) +* ceph-dencoder: refactor build a bit to limit dependencies (Sage Weil, Dan Mick) +* ceph-disk: add Scientific Linux support (Dan van der Ster) +* ceph-disk: do not inadvertantly create directories (Owne Synge) +* ceph-disk: fix dmcrypt support (Sage Weil) +* ceph-disk: fix dmcrypt support (Stephen Taylor) +* ceph-disk: handle corrupt volumes (Stuart Longlang) +* ceph-disk: linter cleanup, logging improvements (Alfredo Deza) +* ceph-disk: partprobe as needed (Eric Eastman) +* ceph-disk: show information about dmcrypt in 'ceph-disk list' output (Sage Weil) +* ceph-disk: use partition type UUIDs and blkid (Sage Weil) +* ceph: fix for non-default cluster names (#8944, Dan Mick) +* ceph-fuse, libcephfs: asok hooks for handling session resets, timeouts (Yan, Zheng) +* ceph-fuse, libcephfs: fix crash in trim_caps (John Spray) +* ceph-fuse, libcephfs: improve cap trimming (John Spray) +* ceph-fuse, libcephfs: improve traceless reply handling (Sage Weil) +* ceph-fuse, libcephfs: virtual xattrs for rstat (Yan, Zheng) +* ceph_objectstore_tool: vastly improved and extended tool for working offline with OSD data stores (David Zafman) +* ceph.spec: many fixes (Erik Logtenberg, Boris Ranto, Dan Mick, Sandon Van Ness) +* ceph.spec: split out ceph-common package, other fixes (Sandon Van Ness) +* ceph_test_librbd_fsx: fix RNG, make deterministic (Ilya Dryomov) +* cephtool: fix help (Yilong Zhao) +* cephtool: refactor and improve CLI tests (Joao Eduardo Luis) +* cephtool: test cleanup (Joao Eduardo Luis) +* clang build fixes (John Spray, Danny Al-Gaaf) +* client: improved MDS session dumps (John Spray) +* common: add config diff admin socket command (Joao Eduardo Luis) +* common: add rwlock assertion checks (Yehuda Sadeh) +* common: fix dup log messages (#9080, Sage Weil) +* common: perfcounters now use atomics and go faster (Sage Weil) +* config: support G, M, K, etc. suffixes (Joao Eduardo Luis) +* coverity cleanups (Danny Al-Gaaf) +* crush: clean up CrushWrapper interface (Xioaxi Chen) +* crush: include new tunables in dump (Sage Weil) +* crush: make ruleset ids unique (Xiaoxi Chen, Loic Dachary) +* crush: only require rule features if the rule is used (#8963, Sage Weil) +* crushtool: send output to stdout, not stderr (Wido den Hollander) +* doc: cache tiering (John Wilkins) +* doc: CRUSH updates (John Wilkins) +* doc: document new upstream wireshark dissector (Kevin Cox) +* doc: improve manual install docs (Francois Lafont) +* doc: keystone integration docs (John Wilkins) +* doc: librados example fixes (Kevin Dalley) +* doc: many doc updates (John Wilkins) +* doc: many install doc updates (John Wilkins) +* doc: misc updates (John Wilkins, Loic Dachary, David Moreau Simard, Wido den Hollander.

vstart.sh: fix/improve rgw support (Luis Pabon, Abhishek Lekshmanan) + +v0.85 +===== + +This is the second-to-last development release before Giant that +contains new functionality. The big items to land during this cycle +are the messenger refactoring from Matt Benjamin that lays some +groundwork for RDMA support, a performance improvement series from +SanDisk that improves performance on SSDs, lots of improvements to our +new standalone civetweb-based RGW frontend, and a new 'osd blocked-by' +mon command that allows admins to easily identify which OSDs are +blocking peering progress. The other big change is that the OSDs and +Monitors now distinguish between "misplaced" and "degraded" objects: +the latter means there are fewer copies than we'd like, while the +former simply means the are not stored in the locations where we want +them to be. + +Also of note is a change to librbd that enables client-side caching by +default. This is coupled with another option that makes the cache +write-through until a "flush" operations is observed: this implies +that the librbd user (usually a VM guest OS) supports barriers and +flush and that it is safe for the cache to switch into writeback mode +without compromising data safety or integrity. It has long been +recommended practice that these options be enabled (e.g., in OpenStack +environments) but until now it has not been the default. + +We have frozen the tree for the looming Giant release, and the next +development release will be a release candidate with a final batch of +new functionality. + +Upgrading +--------- + +* The client-side caching for librbd is now enabled by default (rbd + cache = true).

This release contains +several meaty items, including some MDS improvements for journaling, +the ability to remove the CephFS file system (and name it), several +mon cleanups with tiered pools, several OSD performance branches, a +new "read forward" RADOS caching mode, a prototype Kinetic OSD +backend, and various radosgw improvements (especially with the new +standalone civetweb frontend). And there are a zillion OSD bug +fixes. Things are looking pretty good for the Giant release that is +coming up in the next month. + +Upgrading +--------- + +* The ``*_kb perf`` counters on the monitor have been removed. These are + replaced with a new set of ``*_bytes`` counters (e.g., ``cluster_osd_kb`` is + replaced by ``cluster_osd_bytes``). + +* The ``rd_kb`` and ``wr_kb`` fields in the JSON dumps for pool stats (accessed + via the ``ceph df detail -f json-pretty`` and related commands) have been + replaced with corresponding ``*_bytes`` fields. Similarly, the + ``total_space``, ``total_used``, and ``total_avail`` fields are replaced with + ``total_bytes``, ``total_used_bytes``, and ``total_avail_bytes`` fields. + +* The ``rados df --format=json`` output ``read_bytes`` and ``write_bytes`` + fields were incorrectly reporting ops; this is now fixed. + +* The ``rados df --format=json`` output previously included ``read_kb`` and + ``write_kb`` fields; these have been removed. Please use ``read_bytes`` and + ``write_bytes`` instead (and divide by 1024 if appropriate). + +Notable Changes +--------------- + +* ceph-conf: flush log on exit (Sage Weil) +* ceph-dencoder: refactor build a bit to limit dependencies (Sage Weil, Dan Mick) +* ceph.spec: split out ceph-common package, other fixes (Sandon Van Ness) +* ceph_test_librbd_fsx: fix RNG, make deterministic (Ilya Dryomov) +* cephtool: refactor and improve CLI tests (Joao Eduardo Luis) +* client: improved MDS session dumps (John Spray) +* common: fix dup log messages (#9080, Sage Weil) +* crush: include new tunables in dump (Sage Weil) +* crush: only require rule features if the rule is used (#8963, Sage Weil) +* crushtool: send output to stdout, not stderr (Wido den Hollander) +* fix i386 builds (Sage Weil) +* fix struct vs class inconsistencies (Thorsten Behrens) +* hadoop: update hadoop tests for Hadoop 2.0 (Haumin Chen) +* librbd, ceph-fuse: reduce cache flush overhead (Haomai Wang) +* librbd: fix error path when opening image (#8912, Josh Durgin) +* mds: add file system name, enabled flag (John Spray) +* mds: boot refactor, cleanup (John Spray) +* mds: fix journal conversion with standby-replay (John Spray) +* mds: separate inode recovery queue (John Spray) +* mds: session ls, evict commands (John Spray) +* mds: submit log events in async thread (Yan, Zheng) +* mds: use client-provided timestamp for user-visible file metadata (Yan, Zheng) +* mds: validate journal header on load and save (John Spray) +* misc build fixes for OS X (John Spray) +* misc integer size cleanups (Kevin Cox) +* mon: add get-quota commands (Joao Eduardo Luis) +* mon: do not create file system by default (John Spray) +* mon: fix 'ceph df' output for available space (Xiaoxi Chen) +* mon: fix bug when no auth keys are present (#8851, Joao Eduardo Luis) +* mon: fix compat version for MForward (Joao Eduardo Luis) +* mon: restrict some pool properties to tiered pools (Joao Eduardo Luis) +* msgr: misc locking fixes for fast dispatch (#8891, Sage Weil) +* osd: add 'dump_reservations' admin socket command (Sage Weil) +* osd: add READFORWARD caching mode (Luis Pabon) +* osd: add header cache for KeyValueStore (Haomai Wang) +* osd: add prototype KineticStore based on Seagate Kinetic (Josh Durgin) +* osd: allow map cache size to be adjusted at runtime (Sage Weil) +* osd: avoid refcounting overhead by passing a few things by ref (Somnath Roy) +* osd: avoid sharing PG info that is not durable (Samuel Just) +* osd: clear slow request latency info on osd up/down (Sage Weil) +* osd: fix PG object listing/ordering bug (Guang Yang) +* osd: fix PG stat errors with tiering (#9082, Sage Weil) +* osd: fix bug with long object names and rename (#8701, Sage Weil) +* osd: fix cache full -> not full requeueing (#8931, Sage Weil) +* osd: fix gating of messages from old OSD instances (Greg Farnum) +* osd: fix memstore bugs with collection_move_rename, lock ordering (Sage Weil) +* osd: improve locking for KeyValueStore (Haomai Wang) +* osd: make tiering behave if hit_sets aren't enabled (Sage Weil) +* osd: mark pools with incomplete clones (Sage Weil) +* osd: misc locking fixes for fast dispatch (Samuel Just, Ma Jianpeng) +* osd: prevent old rados clients from using tiered pools (#8714, Sage Weil) +* osd: reduce OpTracker overhead (Somnath Roy) +* osd: set configurable hard limits on object and xattr names (Sage Weil, Haomai Wang) +* osd: trim old EC objects quickly; verify on scrub (Samuel Just) +* osd: work around GCC 4.8 bug in journal code (Matt Benjamin) +* rados bench: fix arg order (Kevin Dalley) +* rados: fix {read,write}_ops values for df output (Sage Weil) +* rbd: add rbdmap pre- and post post- hooks, fix misc bugs (Dmitry Smirnov) +* rbd: improve option default behavior (Josh Durgin) +* rgw: automatically align writes to EC pool (#8442, Yehuda Sadeh) +* rgw: fix crash on swift CORS preflight request (#8586, Yehuda Sadeh) +* rgw: fix memory leaks (Andrey Kuznetsov) +* rgw: fix multipart upload (#8846, Silvain Munaut, Yehuda Sadeh) +* rgw: improve -h (Abhishek Lekshmanan) +* rgw: improve delimited listing of bucket, misc fixes (Yehuda Sadeh) +* rgw: misc civetweb fixes (Yehuda Sadeh) +* rgw: powerdns backend for global namespaces (Wido den Hollander) +* systemd: initial systemd config files (Federico Simoncelli) + + +v0.83 +===== + +Another Ceph development release!
