It is named after the +hammer octopus (Octopus australis). + +v0.94.10 Hammer +=============== + +This Hammer point release fixes several bugs and adds two new features. + +We recommend that all hammer v0.94.x users upgrade. + +For more detailed information, see :download:`the complete changelog <../changelog/v0.94.10.txt>`. + +New Features +------------ + +ceph-objectstore-tool and ceph-monstore-tool now enable user to +rebuild the monitor database from OSDs. (This feature is especially useful when +all monitors fail to boot due to leveldb corruption.) + +In RADOS Gateway, it is now possible to reshard an existing bucket's index +using an off-line tool. + +Usage: + +$ radosgw-admin bucket reshard --bucket=<bucket_name> --num_shards=<num_shards> + +This will create a new linked bucket instance that points to the newly created +index objects. The old bucket instance still exists and currently it's up to +the user to manually remove the old bucket index objects. (Note that bucket +resharding currently requires that all IO (especially writes) to the specific +bucket is quiesced.) + +Other Notable Changes +--------------------- + +* build/ops: ceph-create-keys

The most +important addresses a bug in feature bit enforcement that may prevent +pre-hammer clients from communicating with the cluster during an +upgrade. This only manifests in some cases (for example, when the +'rack' type is in use in the CRUSH map, and possibly other cases), but for +safety we strongly recommend that all users use 0.94.1 instead of 0.94 when +upgrading. + +There is also a fix in the new straw2 buckets when OSD weights are 0. + +We recommend that all v0.94 users upgrade. + +Notable changes +--------------- + +* crush: fix divide-by-0 in straw2 (#11357 Sage Weil) +* crush: fix has_v4_buckets (#11364 Sage Weil) +* osd: fix negative degraded objects during backfilling (#7737 Guang Yang) + +For more detailed information, see :download:`the complete changelog <../changelog/v0.94.1.txt>`. + + +v0.94 Hammer +============ + +This major release is expected to form the basis of the next long-term +stable series. It is intended to supersede v0.80.x Firefly. + +Highlights since 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. +* *Simplified RGW deployment*: the ceph-deploy tool now has a new + 'ceph-deploy rgw create HOST' command that quickly deploys a + instance of the S3/Swift gateway using the embedded Civetweb server. + This is vastly simpler than the previous Apache-based deployment. + There are a few rough edges (e.g., around SSL support) but we + encourage users to try `the new method`_. +* *RGW object versioning*: RGW now supports the S3 object versioning + API, which preserves old version of objects instead of overwriting + them. +* *RGW bucket sharding*: RGW can now shard the bucket index for large + buckets across, improving performance for very large buckets. +* *RBD object maps*: RBD now has an object map function that tracks + which parts of the image are allocating, improving performance for + clones and for commands like export and delete. +* *RBD mandatory locking*: RBD has a new mandatory locking framework + (still disabled by default) that adds additional safeguards to + prevent multiple clients from using the same image at the same time. +* *RBD copy-on-read*: RBD now supports copy-on-read for image clones, + improving performance for some workloads. +* *CephFS snapshot improvements*: Many many bugs have been fixed with + CephFS snapshots. Although they are still disabled by default, + stability has improved significantly. +* *CephFS Recovery tools*: We have built some journal recovery and + diagnostic tools. Stability and performance of single-MDS systems is + vastly improved in Giant, and more improvements have been made now + in Hammer. Although we still recommend caution when storing + important data in CephFS, we do encourage testing for non-critical + workloads so that we can better gauge the feature, usability, + performance, and stability gaps. +* *CRUSH improvements*: We have added a new straw2 bucket algorithm + that reduces the amount of data migration required when changes are + made to the cluster. +* *Shingled erasure codes (SHEC)*: The OSDs now have experimental + support for shingled erasure codes, which allow a small amount of + additional storage to be traded for improved recovery performance. +* *RADOS cache tiering*: A series of changes have been made in the + cache tiering code that improve performance and reduce latency. +* *RDMA support*: There is now experimental support the RDMA via the + Accelio (libxio) library. +* *New administrator commands*: The 'ceph osd df' command shows + pertinent details on OSD disk utilizations. The 'ceph pg ls ...' + command makes it much simpler to query PG states while diagnosing + cluster issues. + +.. _the new method: ../start/quick-ceph-deploy/#add-an-rgw-instance + +Other highlights since Firefly include: + +* *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. + +I would like to take this opportunity to call out the amazing growth +in contributors to Ceph beyond the core development team from Inktank. +Hammer features major new features and improvements from Intel, Fujitsu, +UnitedStack, Yahoo, UbuntuKylin, CohortFS, Mellanox, CERN, Deutsche +Telekom, Mirantis, and SanDisk. + +Dedication +---------- + +This release is dedicated in memoriam to Sandon Van Ness, aka +Houkouonchi, who unexpectedly passed away a few weeks ago. Sandon was +responsible for maintaining the large and complex Sepia lab that +houses the Ceph project's build and test infrastructure. His efforts +have made an important impact on our ability to reliably test Ceph +with a relatively small group of people. He was a valued member of +the team and we will miss him. H is also for Houkouonchi. + +Upgrading +--------- + +* 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 Hammer + * Giant to Hammer + * Dumpling to Firefly to Hammer + +* 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. + +* The ceph-osd daemons will perform a disk-format upgrade improve the + PG metadata layout and to repair a minor bug in the on-disk format. + It may take a minute or two for this to complete, depending on how + many objects are stored on the node; do not be alarmed if they do + not marked "up" by the cluster immediately after starting. + +* If upgrading from v0.93, set + osd enable degraded writes = false + + on all osds prior to upgrading. The degraded writes feature has + been reverted due to 11155. + +* The LTTNG tracing in librbd and librados is disabled in the release packages + until we find a way to avoid violating distro security policies when linking + libust. + +Upgrading from v0.87.x Giant +---------------------------- + +* librbd and librados include lttng tracepoints on distros with + liblttng 2.4 or later (only Ubuntu Trusty for the ceph.com + packages). When running a daemon that uses these libraries, i.e. an + application that calls fork(2) or clone(2) without exec(3), you must + set LD_PRELOAD=liblttng-ust-fork.so.0 to prevent a crash in the + lttng atexit handler when the process exits. The only ceph tool that + requires this is rbd-fuse. + +* If rgw_socket_path is defined and rgw_frontends defines a + socket_port and socket_host, we now allow the rgw_frontends settings + to take precedence. This change should only affect users who have + made non-standard changes to their radosgw configuration. + +* If you are upgrading specifically from v0.92, you must stop all OSD + daemons and flush their journals (``ceph-osd -i NNN + --flush-journal``) before upgrading. There was a transaction + encoding bug in v0.92 that broke compatibility. Upgrading from v0.93, + v0.91, or anything earlier is safe. + +* The experimental 'keyvaluestore-dev' OSD backend has been renamed + 'keyvaluestore' (for simplicity) and marked as experimental. To + enable this untested feature and acknowledge that you understand + that it is untested and may destroy data, you need to add the + following to your ceph.conf:: + + enable experimental unrecoverable data corrupting features = keyvaluestore + +* The following librados C API function calls take a 'flags' argument whose value + is now correctly interpreted: + + rados_write_op_operate() + rados_aio_write_op_operate() + rados_read_op_operate() + rados_aio_read_op_operate() + + The flags were not correctly being translated from the librados constants to the + internal values. Now they are. Any code that is passing flags to these methods + should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_* + constants. + +* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation, + which means the latest CLI cannot run these commands against pre-firefly OSDs. + +* The librados watch/notify API now includes a watch_flush() operation to flush + the async queue of notify operations. This should be called by any watch/notify + user prior to rados_shutdown(). + +* The 'category' field for objects has been removed. This was originally added + to track PG stat summations over different categories of objects for use by + radosgw. It is no longer has any known users and is prone to abuse because it + can lead to a pg_stat_t structure that is unbounded. The librados API calls + that accept this field now ignore it, and the OSD no longer tracks the + per-category summations. + +* The output for 'rados df' has changed. The 'category' level has been + eliminated, so there is now a single stat object per pool. The structure of + the JSON output is different, and the plaintext output has one less column. + +* The 'rados create <objectname> [category]' optional category argument is no + longer supported or recognized. + +* rados.py's Rados class no longer has a __del__ method; it was causing + problems on interpreter shutdown and use of threads. If your code has + Rados objects with limited lifetimes and you're concerned about locked + resources, call Rados.shutdown() explicitly. + +* There is a new version of the librados watch/notify API with vastly + improved semantics. Any applications using this interface are + encouraged to migrate to the new API. The old API calls are marked + as deprecated and will eventually be removed. + +* The librados rados_unwatch() call used to be safe to call on an + invalid handle. The new version has undefined behavior when passed + a bogus value (for example, when rados_watch() returns an error and + handle is not defined). + +* The structure of the formatted 'pg stat' command is changed for the + portion that counts states by name to avoid using the '+' character + (which appears in state names) as part of the XML token (it is not + legal). + +* Previously, the formatted output of 'ceph pg stat -f ...' was a full + pg dump that included all metadata about all PGs in the system. It + is now a concise summary of high-level PG stats, just like the + unformatted 'ceph pg stat' command. + +* All JSON dumps of floating point values were incorrecting surrounding the + value with quotes. These quotes have been removed. Any consumer of structured + JSON output that was consuming the floating point values was previously having + to interpret the quoted string and will most likely need to be fixed to take + the unquoted number. + +* New ability to list all objects from all namespaces that can fail or + return incomplete results when not all OSDs have been upgraded. + Features rados --all ls, rados cppool, rados export, rados + cache-flush-evict-all and rados cache-try-flush-evict-all can also + fail or return incomplete results. + +* Due to a change in the Linux kernel version 3.18 and the limits of the FUSE + interface, ceph-fuse needs be mounted as root on at least some systems. See + issues #9997, #10277, and #10542 for details. + +Upgrading from v0.80x Firefly (additional notes) +------------------------------------------------ + +* 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 v0.93 +--------------------------- + +* build: a few cmake fixes (Matt Benjamin) +* build: fix build on RHEL/CentOS 5.9 (Rohan Mars) +* build: reorganize Makefile to allow modular builds (Boris Ranto) +* ceph-fuse: be more forgiving on remount (#10982 Greg Farnum) +* ceph: improve CLI parsing (#11093 David Zafman) +* common: fix cluster logging to default channel (#11177 Sage Weil) +* crush: fix parsing of straw2 buckets (#11015 Sage Weil) +* doc: update man pages (David Zafman) +* librados: fix leak in C_TwoContexts (Xiong Yiliang) +* librados: fix leak in watch/notify path (Sage Weil) +* librbd: fix and improve AIO cache invalidation (#10958 Jason Dillaman) +* librbd: fix memory leak (Jason Dillaman) +* librbd: fix ordering/queueing of resize operations (Jason Dillaman) +* librbd: validate image is r/w on resize/flatten (Jason Dillaman) +* librbd: various internal locking fixes (Jason Dillaman) +* lttng: tracing is disabled until we streamline dependencies (Josh Durgin) +* mon: add bootstrap-rgw profile (Sage Weil) +* mon: do not pollute mon dir with CSV files from CRUSH check (Loic Dachary) +* mon: fix clock drift time check interval (#10546 Joao Eduardo Luis) +* mon: fix units in store stats (Joao Eduardo Luis) +* mon: improve error handling on erasure code profile set (#10488, #11144 Loic Dachary) +* mon: set {read,write}_tier on 'osd tier add-cache ...'

before Hammer. Big items +include additional checksums on OSD objects, proxied reads in the +cache tier, image locking in RBD, optimized OSD Transaction and +replication messages, and a big pile of RGW and MDS bug fixes. + +Upgrading +--------- + +* The experimental 'keyvaluestore-dev' OSD backend has been renamed + 'keyvaluestore' (for simplicity) and marked as experimental. To + enable this untested feature and acknowledge that you understand + that it is untested and may destroy data, you need to add the + following to your ceph.conf:: + + enable experimental unrecoverable data corrupting features = keyvaluestore + +* The following librados C API function calls take a 'flags' argument whose value + is now correctly interpreted: + + rados_write_op_operate() + rados_aio_write_op_operate() + rados_read_op_operate() + rados_aio_read_op_operate() + + The flags were not correctly being translated from the librados constants to the + internal values. Now they are. Any code that is passing flags to these methods + should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_* + constants. + +* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation, + which means the latest CLI cannot run these commands against pre-firefly OSDs. + +* The librados watch/notify API now includes a watch_flush() operation to flush + the async queue of notify operations.

The headline items are +subtree-based quota support in CephFS (ceph-fuse/libcephfs client +support only for now), a rewrite of the watch/notify librados API used +by RBD and RGW, OSDMap checksums to ensure that maps are always +consistent inside the cluster, new API calls in librados and librbd +for IO hinting modeled after posix_fadvise, and improved storage of +per-PG state. + +We expect two more releases before the Hammer feature freeze (v0.93). + +Upgrading +--------- + +* The 'category' field for objects has been removed. This was originally added + to track PG stat summations over different categories of objects for use by + radosgw. It is no longer has any known users and is prone to abuse because it + can lead to a pg_stat_t structure that is unbounded. The librados API calls + that accept this field now ignore it, and the OSD no longer tracks the + per-category summations. + +* The output for 'rados df' has changed. The 'category' level has been + eliminated, so there is now a single stat object per pool. The structure of + the JSON output is different, and the plaintext output has one less column. + +* The 'rados create <objectname> [category]' optional category argument is no + longer supported or recognized. + +* rados.py's Rados class no longer has a __del__ method; it was causing + problems on interpreter shutdown and use of threads. If your code has + Rados objects with limited lifetimes and you're concerned about locked + resources, call Rados.shutdown() explicitly. + +* There is a new version of the librados watch/notify API with vastly + improved semantics. Any applications using this interface are + encouraged to migrate to the new API. The old API calls are marked + as deprecated and will eventually be removed. + +* The librados rados_unwatch() call used to be safe to call on an + invalid handle. The new version has undefined behavior when passed + a bogus value (for example, when rados_watch() returns an error and + handle is not defined). + +* The structure of the formatted 'pg stat' command is changed for the + portion that counts states by name to avoid using the '+' character + (which appears in state names) as part of the XML token (it is not + legal). + +Notable Changes +--------------- + +* asyncmsgr: misc fixes (Haomai Wang) +* buffer: add 'shareable' construct (Matt Benjamin) +* build: aarch64 build fixes (Noah Watkins, Haomai Wang) +* build: support for jemalloc (Shishir Gowda) +* ceph-disk: allow journal partition re-use (#10146 Loic Dachary, Dav van der Ster) +* ceph-disk: misc fixes (Christos Stavrakakis) +* ceph-fuse: fix kernel cache trimming (#10277 Yan, Zheng) +* ceph-objectstore-tool: many many improvements (David Zafman) +* common: support new gperftools header locations (Key Dreyer) +* crush: straw bucket weight calculation fixes (#9998 Sage Weil) +* doc: misc improvements (Nilamdyuti Goswami, John Wilkins, Chris Holcombe) +* libcephfs,ceph-fuse: add 'status' asok (John Spray) +* librados, osd: new watch/notify implementation (Sage Weil) +* librados: drop 'category' feature (Sage Weil) +* librados: fix pool deletion handling (#10372 Sage Weil) +* librados: new fadvise API (Ma Jianpeng) +* libradosstriper: fix remove() (Dongmao Zhang) +* librbd: complete pending ops before closing image (#10299 Josh Durgin) +* librbd: fadvise API (Ma Jianpeng) +* mds: ENOSPC and OSDMap epoch barriers (#7317 John Spray) +* mds: dirfrag buf fix (Yan, Zheng) +* mds: disallow most commands on inactive MDS's (Greg Farnum) +* mds: drop dentries, leases on deleted directories (#10164 Yan, Zheng) +* mds: handle zero-size xattr (#10335 Yan, Zheng) +* mds: subtree quota support (Yunchuan Wen) +* memstore: free space tracking (John Spray) +* misc cleanup (Danny Al-Gaaf, David Anderson) +* mon: 'osd crush reweight-all' command (Sage Weil) +* mon: allow full flag to be manually cleared (#9323 Sage Weil) +* mon: delay failure injection (Joao Eduardo Luis) +* mon: fix paxos timeouts (#10220 Joao Eduardo Luis) +* mon: get canonical OSDMap from leader (#10422 Sage Weil) +* msgr: fix RESETSESSION bug (#10080 Greg Farnum) +* objectstore: deprecate collection attrs (Sage Weil) +* osd, mon: add checksums to all OSDMaps (Sage Weil) +* osd: allow deletion of objects with watcher (#2339 Sage Weil) +* osd: allow sparse read for Push/Pull (Haomai Wang) +* osd: cache reverse_nibbles hash value (Dong Yuan) +* osd: drop upgrade support for pre-dumpling (Sage Weil) +* osd: enable and use posix_fadvise (Sage Weil) +* osd: erasure-code: enforce chunk size alignment (#10211 Loic Dachary) +* osd: erasure-code: jerasure support for NEON (Loic Dachary) +* osd: erasure-code: relax cauchy w restrictions (#10325 David Zhang, Loic Dachary) +* osd: erasure-code: update gf-complete to latest upstream (Loic Dachary) +* osd: fix WBTHrottle perf counters (Haomai Wang) +* osd: fix backfill bug (#10150 Samuel Just) +* osd: fix occasional peering stalls (#10431 Sage Weil) +* osd: fix scrub vs try-flush bug (#8011 Samuel Just) +* osd: fix stderr with -f or -d (Dan Mick) +* osd: misc FIEMAP fixes (Ma Jianpeng) +* osd: optimize Finisher (Xinze Chi) +* osd: store PG metadata in per-collection objects for better concurrency (Sage Weil) +* pyrados: add object lock support (#6114 Mehdi Abaakouk) +* pyrados: fix misnamed wait_* routings (#10104 Dan Mick) +* pyrados: misc cleanups (Kefu Chai) +* qa: add large auth ticket tests (Ilya Dryomov) +* qa: many 'make check' improvements (Loic Dachary) +* qa: misc tests (Loic Dachary, Yan, Zheng) +* rgw: conditional PUT on ETag (#8562 Ray Lv) +* rgw: fix error codes (#10334 #10329 Yehuda Sadeh) +* rgw: index swift keys appropriately (#10471 Yehuda Sadeh) +* rgw: prevent illegal bucket policy that doesn't match placement rule (Yehuda Sadeh) +* rgw: run radosgw as apache with systemd (#10125 Loic Dachary) +* rgw: support X-Storage-Policy header for Swift storage policy compat (Yehuda Sadeh) +* rgw: use \r\n for http headers (#9254 Yehuda Sadeh) +* rpm: misc fixes (Key Dreyer) + + +v0.90 +===== + +This is the last development release before Christmas. There are some +API cleanups for librados and librbd, and lots of bug fixes across the +board for the OSD, MDS, RGW, and CRUSH. The OSD also gets support for +discard (potentially helpful on SSDs, although it is off by default), and there +are several improvements to ceph-disk. + +The next two development releases will be getting a slew of new +functionality for hammer. Stay tuned! + +Upgrading +--------- + +* Previously, the formatted output of 'ceph pg stat -f ...' was a full + pg dump that included all metadata about all PGs in the system. It + is now a concise summary of high-level PG stats, just like the + unformatted 'ceph pg stat' command. + +* All JSON dumps of floating point values were incorrecting surrounding the + value with quotes. These quotes have been removed. Any consumer of structured + JSON output that was consuming the floating point values was previously having + to interpret the quoted string and will most likely need to be fixed to take + the unquoted number. + +Notable Changes +--------------- + +* arch: fix NEON feaeture detection (#10185 Loic Dachary) +* build: adjust build deps for yasm, virtualenv (Jianpeng Ma) +* build: improve build dependency tooling (Loic Dachary) +* ceph-disk: call partx/partprobe consistency (#9721 Loic Dachary) +* ceph-disk: fix dmcrypt key permissions (Loic Dachary) +* ceph-disk: fix umount race condition (#10096 Blaine Gardner) +* ceph-disk: init=none option (Loic Dachary) +* ceph-monstore-tool: fix shutdown (#10093 Loic Dachary) +* ceph-objectstore-tool: fix import (#10090 David Zafman) +* ceph-objectstore-tool: many improvements and tests (David Zafman) +* ceph.spec: package rbd-replay-prep (Ken Dreyer) +* common: add 'perf reset ...' admin command (Jianpeng Ma) +* common: do not unlock rwlock on destruction (Federico Simoncelli) +* common: fix block device discard check (#10296 Sage Weil) +* common: remove broken CEPH_LOCKDEP optoin (Kefu Chai) +* crush: fix tree bucket behavior (Rongze Zhu) +* doc: add build-doc guidlines for Fedora and CentOS/RHEL (Nilamdyuti Goswami) +* doc: enable rbd cache on openstack deployments (Sebastien Han) +* doc: improved installation nots on CentOS/RHEL installs (John Wilkins) +* doc: misc cleanups (Adam Spiers, Sebastien Han, Nilamdyuti Goswami, Ken Dreyer, John Wilkins) +* doc: new man pages (Nilamdyuti Goswami) +* doc: update release descriptions (Ken Dreyer) +* doc: update sepia hardware inventory (Sandon Van Ness) +* librados: only export public API symbols (Jason Dillaman) +* libradosstriper: fix stat strtoll (Dongmao Zhang) +* libradosstriper: fix trunc method (#10129 Sebastien Ponce) +* librbd: fix list_children from invalid pool ioctxs (#10123 Jason Dillaman) +* librbd: only export public API symbols (Jason Dillaman) +* many coverity fixes (Danny Al-Gaaf) +* mds: 'flush journal' admin command (John Spray) +* mds: fix MDLog IO callback deadlock (John Spray) +* mds: fix deadlock during journal probe vs purge (#10229 Yan, Zheng) +* mds: fix race trimming log segments (Yan, Zheng) +* mds: store backtrace for stray dir (Yan, Zheng) +* mds: verify backtrace when fetching dirfrag (#9557 Yan, Zheng) +* mon: add max pgs per osd warning (Sage Weil) +* mon: fix *_ratio* units and types (Sage Weil) +* mon: fix JSON dumps to dump floats as flots and not strings (Sage Weil) +* mon: fix formatter 'pg stat' command output (Sage Weil) +* msgr: async: several fixes (Haomai Wang) +* msgr: simple: fix rare deadlock (Greg Farnum) +* osd: batch pg log trim (Xinze Chi) +* osd: clean up internal ObjectStore interface (Sage Weil) +* osd: do not abort deep scrub on missing hinfo (#10018 Loic Dachary) +* osd: fix ghobject_t formatted output to include shard (#10063 Loic Dachary) +* osd: fix osd peer check on scrub messages (#9555 Sage Weil) +* osd: fix pgls filter ops (#9439 David Zafman) +* osd: flush snapshots from cache tier immediately (Sage Weil) +* osd: keyvaluestore: fix getattr semantics (Haomai Wang) +* osd: keyvaluestore: fix key ordering (#10119 Haomai Wang) +* osd: limit in-flight read requests (Jason Dillaman) +* osd: log when scrub or repair starts (Loic Dachary) +* osd: support for discard for journal trim (Jianpeng Ma) +* qa: fix osd create dup tests (#10083 Loic Dachary) +* rgw: add location header when object is in another region (VRan Liu) +* rgw: check timestamp on s3 keystone auth (#10062 Abhishek Lekshmanan) +* rgw: make sysvinit script set ulimit -n properly (Sage Weil) +* systemd: better systemd unit files (Owen Synge) +* tests: ability to run unit tests under docker (Loic Dachary) + + +v0.89 +===== + +This is the second development release since Giant.
