We recommend +that all users update to this release. + +Notable Changes +--------------- + +* Cephfs: The ``AT_NO_ATTR_SYNC`` macro is deprecated, please use the standard + ``AT_STATX_DONT_SYNC`` macro. The ``AT_NO_ATTR_SYNC`` macro will be removed in + the future. + +* OSD: The issue of high CPU utilization during recovery/backfill operations + has been fixed. For more details see: https://tracker.ceph.com/issues/56530. + +* Trimming of PGLog dups is now controlled by size instead of the version. + This fixes the PGLog inflation issue that was happening when online + (in OSD) trimming jammed after a PG split operation. Also, a new offline + mechanism has been added: ``ceph-objectstore-tool`` now has a ``trim-pg-log-dups`` op + that targets situations where an OSD is unable to boot due to those inflated dups. + If that is the case, in OSD logs the "You can be hit by THE DUPS BUG" warning + will be visible. + Relevant tracker: https://tracker.ceph.com/issues/53729 + +* OSD: Octopus modified the SnapMapper key format from + ``<LEGACY_MAPPING_PREFIX><snapid>_<shardid>_<hobject_t::to_str()>`` + to + ``<MAPPING_PREFIX><pool>_<snapid>_<shardid>_<hobject_t::to_str()>``. + When this change was introduced, `94ebe0e <https://github.com/ceph/ceph/commit/94ebe0eab968068c29fdffa1bfe68c72122db633>`_ + also introduced a conversion with a crucial bug which essentially + destroyed legacy keys by mapping them to + ``<MAPPING_PREFIX><poolid>_<snapid>_`` + without the object-unique suffix. The conversion is fixed in this release. + Relevant tracker: https://tracker.ceph.com/issues/56147 + +Changelog +--------- + +* .readthedocs.yml: Always build latest doc/releases pages (`pr#47442 <https://github.com/ceph/ceph/pull/47442>`_, David Galloway) +* Add mapping for ernno:13 and adding path in error msg in opendir()/cephfs.pyx (`pr#46647 <https://github.com/ceph/ceph/pull/46647>`_, Sarthak0702) +* admin: Fix check if PR or release branch docs build (`pr#47739 <https://github.com/ceph/ceph/pull/47739>`_, David Galloway) +* bdev: fix FTBFS on FreeBSD, keep the huge paged read buffers (`pr#44641 <https://github.com/ceph/ceph/pull/44641>`_, Radoslaw Zarzynski) +* build: Silence deprecation warnings from OpenSSL 3 (`pr#47585 <https://github.com/ceph/ceph/pull/47585>`_, Kefu Chai, Adam C.

The bug was exposed due to 17.2.2 being built with gcc 8.5.0-14, which contains + a new patch to check for invalid regex. 17.2.1 was built using gcc 8.5.0-13, which + does not contain the invalid regex patch. + + Relevant tracker: https://tracker.ceph.com/issues/55304 + + Relevant BZ: https://bugzilla.redhat.com/show_bug.cgi?id=2110797 + +Changelog +--------- + +* libcephsqlite: ceph-mgr crashes when compiled with gcc12 (`pr#47270 <https://github.com/ceph/ceph/pull/47270>`_, Ganesh Maharaj Mahalingam) + +v17.2.2 Quincy +============== + +This is a hotfix release that resolves two security flaws. + +Notable Changes +--------------- +* Users who were running OpenStack Manila to export native CephFS, who + upgraded their Ceph cluster from Nautilus (or earlier) to a later + major version, were vulnerable to an attack by malicious users. The + vulnerability allowed users to obtain access to arbitrary portions of + the CephFS filesystem hierarchy, instead of being properly restricted + to their own subvolumes. The vulnerability is due to a bug in the + "volumes" plugin in Ceph Manager. This plugin is responsible for + managing Ceph File System subvolumes which are used by OpenStack + Manila services as a way to provide shares to Manila users. + + With this hotfix, the vulnerability is fixed. Administrators who are + concerned they may have been impacted should audit the CephX keys in + their cluster for proper path restrictions. + + Again, this vulnerability only impacts OpenStack Manila clusters which + provided native CephFS access to their users. + +* A regression made it possible to dereference a null pointer for + for s3website requests that don't refer to a bucket resulting in an RGW + segfault. + +Changelog +--------- +* mgr/volumes: Fix subvolume discover during upgrade (:ref:`CVE-2022-0670`, Kotresh HR) +* mgr/volumes: V2 Fix for test_subvolume_retain_snapshot_invalid_recreate (:ref:`CVE-2022-0670`, Kotresh HR) +* qa: validate subvolume discover on upgrade (Kotresh HR) +* rgw: s3website check for bucket before retargeting (Seena Fallah) + +v17.2.1 Quincy +============== + +This is the first bugfix release of Ceph Quincy. + +Notable Changes +--------------- +* The "BlueStore zero block detection" feature (first introduced to Quincy in + https://github.com/ceph/ceph/pull/43337) has been turned off by default with a + new global option called `bluestore_zero_block_detection`. This feature, + intended for large-scale synthetic testing, does not interact well with some RBD + and CephFS features. Any side effects experienced in previous Quincy versions + would no longer occur, provided that the config option remains set to false. + Relevant tracker: https://tracker.ceph.com/issues/55521 + +* telemetry: Added new Rook metrics to the 'basic' channel to report Rook's + version, Kubernetes version, node metrics, etc. + See a sample report with `ceph telemetry preview`. + Opt-in with `ceph telemetry on`. + + For more details, see: + + https://docs.ceph.com/en/latest/mgr/telemetry/ + +* Add offline dup op trimming ability in the ceph-objectstore-tool. + Relevant tracker: https://tracker.ceph.com/issues/53729 + +* Fixes a bug with cluster logs not being populated after log rotation. + Relevant tracker: https://tracker.ceph.com/issues/55383 + +Changelog +--------- +* .github/CODEOWNERS: tag core devs on core PRs (`pr#46519 <https://github.com/ceph/ceph/pull/46519>`_, Neha Ojha) +* .github: continue on error and reorder milestone step (`pr#46447 <https://github.com/ceph/ceph/pull/46447>`_, Ernesto Puerta) +* [quincy] mgr/alerts: Add Message-Id and Date header to sent emails (`pr#46311 <https://github.com/ceph/ceph/pull/46311>`_, Lorenz Bausch) +* ceph-fuse: ignore fuse mount failure if path is already mounted (`pr#45939 <https://github.com/ceph/ceph/pull/45939>`_, Nikhilkumar Shelke) +* ceph.in: clarify the usage of `--format` in the ceph command (`pr#46246 <https://github.com/ceph/ceph/pull/46246>`_, Laura Flores) +* ceph.spec.in: disable annobin plugin if compile with gcc-toolset (`pr#46377 <https://github.com/ceph/ceph/pull/46377>`_, Kefu Chai) +* ceph.spec.in: remove build directory at end of %install (`pr#45697 <https://github.com/ceph/ceph/pull/45697>`_, Tim Serong) +* ceph.spec.in: Use libthrift-devel on SUSE distros (`pr#45700 <https://github.com/ceph/ceph/pull/45700>`_, Tim Serong) +* ceph.spec: make ninja-build package install always (`pr#45875 <https://github.com/ceph/ceph/pull/45875>`_, Deepika Upadhyay) +* Cephadm Batch Backport April (`pr#46055 <https://github.com/ceph/ceph/pull/46055>`_, Adam King, Lukas Mayer, Ken Dreyer, Redouane Kachach, Aashish Sharma, Avan Thakkar, Moritz Röhrich, Teoman ONAY, Melissa Li, Christoph Glaubitz, Guillaume Abrioux, wangyunqing, Joseph Sawaya, Matan Breizman, Pere Diaz Bou, Michael Fritch, Patrick C.

BlueStore is Ceph's default object + store. + +* The `ceph-mgr-modules-core` debian package no longer recommends + `ceph-mgr-rook`. `ceph-mgr-rook` depends on `python3-numpy`, which + cannot be imported in different Python sub-interpreters multiple times + when the version of `python3-numpy` is older than 1.19. Because + `apt-get` installs the `Recommends` packages by default, `ceph-mgr-rook` + was always installed along with the `ceph-mgr` debian package as an + indirect dependency. If your workflow depends on this behavior, you + might want to install `ceph-mgr-rook` separately. + +* The ``device_health_metrics`` pool has been renamed ``.mgr``. It is now + used as a common store for all ``ceph-mgr`` modules. After upgrading to + Quincy, the ``device_health_metrics`` pool will be renamed to ``.mgr`` + on existing clusters. + +* The ``ceph pg dump`` command now prints three additional columns: + `LAST_SCRUB_DURATION` shows the duration (in seconds) of the last completed + scrub; + `SCRUB_SCHEDULING` conveys whether a PG is scheduled to be scrubbed at a + specified time, whether it is queued for scrubbing, or whether it is being + scrubbed; + `OBJECTS_SCRUBBED` shows the number of objects scrubbed in a PG after a + scrub begins. + +* A health warning is now reported if the ``require-osd-release`` flag + is not set to the appropriate release after a cluster upgrade. + +* LevelDB support has been removed. ``WITH_LEVELDB`` is no longer a supported + build option. Users *should* migrate their monitors and OSDs to RocksDB + before upgrading to Quincy. + +* Cephadm: ``osd_memory_target_autotune`` is enabled by default, which sets + ``mgr/cephadm/autotune_memory_target_ratio`` to ``0.7`` of total RAM. This + is unsuitable for hyperconverged infrastructures. For hyperconverged Ceph, + please refer to the documentation or set + ``mgr/cephadm/autotune_memory_target_ratio`` to ``0.2``. + +* telemetry: Improved the opt-in flow so that users can keep sharing the same + data, even when new data collections are available. A new 'perf' channel that + collects various performance metrics is now available for operators to opt + into with: + `ceph telemetry on` + `ceph telemetry enable channel perf` + See a sample report with `ceph telemetry preview`. + Note that generating a telemetry report with 'perf' channel data might + take a few moments in big clusters. + For more details, see: + https://docs.ceph.com/en/quincy/mgr/telemetry/ + +* MGR: The progress module disables the pg recovery event by default since the + event is expensive and has interrupted other services when there are OSDs + being marked in/out from the cluster. However, the user can still enable + this event anytime. For more detail, see: + + https://docs.ceph.com/en/quincy/mgr/progress/ + +* https://tracker.ceph.com/issues/55383 is a known issue - + to continue to log cluster log messages to file, + run `ceph config set mon mon_cluster_log_to_file true` after every log rotation. + +Cephadm +------- + +* SNMP Support +* Colocation of Daemons (mgr, mds, rgw) +* osd memory autotuning +* Integration with new NFS mgr module +* Ability to zap osds as they are removed +* cephadm agent for increased performance/scalability + +Dashboard +~~~~~~~~~ +* Day 1: the new "Cluster Expansion Wizard" will guide users through post-install steps: + adding new hosts, storage devices or services. +* NFS: the Dashboard now allows users to fully manage all NFS exports from a single place. +* New mgr module (feedback): users can quickly report Ceph tracker issues + or suggestions directly from the Dashboard or the CLI. +* New "Message of the Day": cluster admins can publish a custom message in a banner. +* Cephadm integration improvements: + * Host management: maintenance, specs and labelling, + * Service management: edit and display logs, + * Daemon management (start, stop, restart, reload), + * New services supported: ingress (HAProxy) and SNMP-gateway. +* Monitoring and alerting: + * 43 new alerts have been added (totalling 68) improving observability of events affecting: + cluster health, monitors, storage devices, PGs and CephFS. + * Alerts can now be sent externally as SNMP traps via the new SNMP gateway service + (the MIB is provided). + * Improved integrated full/nearfull event notifications. + * Grafana Dashboards now use grafonnet format (though they're still available + in JSON format). + * Stack update: images for monitoring containers have been updated. + Grafana 8.3.5, Prometheus 2.33.4, Alertmanager 0.23.0 and Node Exporter 1.3.1. + This reduced exposure to several Grafana vulnerabilities (CVE-2021-43798, + CVE-2021-39226, CVE-2021-43798, CVE-2020-29510, CVE-2020-29511). + +RADOS +~~~~~ + +* OSD: Ceph now uses `mclock_scheduler` for BlueStore OSDs as its default + `osd_op_queue` to provide QoS. The 'mclock_scheduler' is not supported + for Filestore OSDs. Therefore, the default 'osd_op_queue' is set to `wpq` + for Filestore OSDs and is enforced even if the user attempts to change it. + For more details on configuring mclock see, + + https://docs.ceph.com/en/quincy/rados/configuration/mclock-config-ref/ + + An outstanding issue exists during runtime where the mclock config options + related to reservation, weight and limit cannot be modified after switching + to the `custom` mclock profile using the `ceph config set ...` command. + This is tracked by: https://tracker.ceph.com/issues/55153. Until the issue + is fixed, users are advised to avoid using the 'custom' profile or use the + workaround mentioned in the tracker. + +* MGR: The pg_autoscaler can now be turned `on` and `off` globally + with the `noautoscale` flag. By default, it is set to `on`, but this flag + can come in handy to prevent rebalancing triggered by autoscaling during + cluster upgrade and maintenance. Pools can now be created with the `--bulk` + flag, which allows the autoscaler to allocate more PGs to such pools. This + can be useful to get better out of the box performance for data-heavy pools. + + For more details about autoscaling, see: + https://docs.ceph.com/en/quincy/rados/operations/placement-groups/ + +* OSD: Support for on-wire compression for osd-osd communication, `off` by + default. + + For more details about compression modes, see: + https://docs.ceph.com/en/quincy/rados/configuration/msgr2/#compression-modes + +* OSD: Concise reporting of slow operations in the cluster log. The old + and more verbose logging behavior can be regained by setting + `osd_aggregated_slow_ops_logging` to false. + +* the "kvs" Ceph object class is not packaged anymore. The "kvs" Ceph + object class offers a distributed flat b-tree key-value store that + is implemented on top of the librados objects omap. Because there + are no existing internal users of this object class, it is not + packaged anymore. + +RBD block storage +~~~~~~~~~~~~~~~~~ + +* rbd-nbd: `rbd device attach` and `rbd device detach` commands added, + these allow for safe reattach after `rbd-nbd` daemon is restarted since + Linux kernel 5.14. + +* rbd-nbd: `notrim` map option added to support thick-provisioned images, + similar to krbd. + +* Large stabilization effort for client-side persistent caching on SSD + devices, also available in 16.2.8. For details on usage, see: + + https://docs.ceph.com/en/quincy/rbd/rbd-persistent-write-log-cache/ + +* Several bug fixes in diff calculation when using fast-diff image + feature + whole object (inexact) mode. In some rare cases these + long-standing issues could cause an incorrect `rbd export`. Also + fixed in 15.2.16 and 16.2.8. + +* Fix for a potential performance degradation when running Windows VMs + on krbd. For details, see `rxbounce` map option description: + + https://docs.ceph.com/en/quincy/man/8/rbd/#kernel-rbd-krbd-options + +RGW object storage +~~~~~~~~~~~~~~~~~~ + +* RGW now supports rate limiting by user and/or by bucket. With this + feature it is possible to limit user and/or bucket, the total operations + and/or bytes per minute can be delivered. This feature allows the + admin to limit only READ operations and/or WRITE operations. The + rate-limiting configuration could be applied on all users and all buckets + by using global configuration. + +* `radosgw-admin realm delete` has been renamed to `radosgw-admin realm + rm`. This is consistent with the help message. + +* S3 bucket notification events now contain an `eTag` key instead of + `etag`, and eventName values no longer carry the `s3:` prefix, fixing + deviations from the message format that is observed on AWS. + +* It is possible to specify ssl options and ciphers for beast frontend + now. The default ssl options setting is + "no_sslv2:no_sslv3:no_tlsv1:no_tlsv1_1". If you want to return to the old + behavior, add 'ssl_options=' (empty) to the ``rgw frontends`` configuration. + +* The behavior for Multipart Upload was modified so that only + CompleteMultipartUpload notification is sent at the end of the multipart + upload. The POST notification at the beginning of the upload and the PUT + notifications that were sent on each part are no longer sent. + + +CephFS distributed file system +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* fs: A file system can be created with a specific ID ("fscid"). This is + useful in certain recovery scenarios (for example, when a monitor + database has been lost and rebuilt, and the restored file system is + expected to have the same ID as before). + +* fs: A file system can be renamed using the `fs rename` command. Any cephx + credentials authorized for the old file system name will need to be + reauthorized to the new file system name. Since the operations of the clients + using these re-authorized IDs may be disrupted, this command requires the + "--yes-i-really-mean-it" flag. Also, mirroring is expected to be disabled + on the file system. + +* MDS upgrades no longer require all standby MDS daemons to be stoped before + upgrading a file systems's sole active MDS. + +* CephFS: Failure to replay the journal by a standby-replay daemon now + causes the rank to be marked "damaged". + +Upgrading from Octopus or Pacific +---------------------------------- + +Quincy does not support LevelDB. Please migrate your OSDs and monitors +to RocksDB before upgrading to Quincy. + +Before starting, make sure your cluster is stable and healthy (no down or +recovering OSDs). (This is optional, but recommended.) You can disable +the autoscaler for all pools during the upgrade using the noautoscale flag. + +.. note:: + + You can monitor the progress of your upgrade at each stage with the + ``ceph versions`` command, which will tell you what ceph version(s) are + running for each type of daemon. + +Upgrading cephadm clusters +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If your cluster is deployed with cephadm (first introduced in Octopus), then +the upgrade process is entirely automated. To initiate the upgrade, + + .. prompt:: bash # + + ceph orch upgrade start --ceph-version 17.2.0 + +The same process is used to upgrade to future minor releases. + +Upgrade progress can be monitored with ``ceph -s`` (which provides a simple +progress bar) or more verbosely with + + .. prompt:: bash # + + ceph -W cephadm + +The upgrade can be paused or resumed with + + .. prompt:: bash # + + ceph orch upgrade pause # to pause + ceph orch upgrade resume # to resume + +or canceled with + + .. prompt:: bash # + + ceph orch upgrade stop + +Note that canceling the upgrade simply stops the process; there is no ability to +downgrade back to Octopus or Pacific. + + +Upgrading non-cephadm clusters +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. note:: + If you cluster is running Octopus (15.2.x) or later, you might choose + to first convert it to use cephadm so that the upgrade to Quincy + is automated (see above). For more information, see + :ref:`cephadm-adoption`. + +#. Set the ``noout`` flag for the duration of the upgrade. (Optional, + but recommended.): + + .. prompt:: bash # + + ceph osd set noout + +#. Upgrade monitors by installing the new packages and restarting the + monitor daemons. For example, on each monitor host,: + + .. prompt:: bash # + + systemctl restart ceph-mon.target + + Once all monitors are up, verify that the monitor upgrade is + complete by looking for the ``quincy`` string in the mon + map. The command: + + .. prompt:: bash # + + ceph mon dump | grep min_mon_release + + should report:: + + min_mon_release 17 (quincy) + + If it doesn't, that implies that one or more monitors hasn't been + upgraded and restarted and/or the quorum does not include all monitors. + +#. Upgrade ``ceph-mgr`` daemons by installing the new packages and + restarting all manager daemons. For example, on each manager host,: + + .. prompt:: bash # + + systemctl restart ceph-mgr.target + + Verify the ``ceph-mgr`` daemons are running by checking ``ceph + -s``: + + .. prompt:: bash # + + ceph -s + + :: + + ... + services: + mon: 3 daemons, quorum foo,bar,baz + mgr: foo(active), standbys: bar, baz + ... + +#. Upgrade all OSDs by installing the new packages and restarting the + ceph-osd daemons on all OSD hosts: + + .. prompt:: bash # + + systemctl restart ceph-osd.target + +#. Upgrade all CephFS MDS daemons. For each CephFS file system, + + #. Disable standby_replay. Before executing, note the current value + so that it may be re-enabled after the upgrade (if currently enabled): + + .. prompt:: bash # + + ceph fs get <fs_name> | grep allow_standby_replay + ceph fs set <fs_name> allow_standby_replay false + + #. Reduce the number of ranks to 1. (Make note of the original + number of MDS daemons first if you plan to restore it later.): + + .. prompt:: bash # + + ceph fs status + ceph fs set <fs_name> max_mds 1 + + #. Wait for the cluster to deactivate any non-zero ranks by + periodically checking the status: + + .. prompt:: bash # + + ceph fs status + + #. Take all standby MDS daemons offline on the appropriate hosts with: + + .. prompt:: bash # + + systemctl stop ceph-mds@<daemon_name> + + #. Confirm that only one MDS is online and is rank 0 for your FS: + + .. prompt:: bash # + + ceph fs status + + #. Upgrade the last remaining MDS daemon by installing the new + packages and restarting the daemon: + + .. prompt:: bash # + + systemctl restart ceph-mds.target + + #. Restart all standby MDS daemons that were taken offline: + + .. prompt:: bash # + + systemctl start ceph-mds.target + + #. Restore the original value of ``max_mds`` for the volume: + + .. prompt:: bash # + + ceph fs set <fs_name> max_mds <original_max_mds> + + #. Restore the original value of ``allow_standby_replay`` for the volume if + it was ``true``: + + .. prompt:: bash # + + ceph fs set <fs_name> allow_standby_replay true + +#. Upgrade all radosgw daemons by upgrading packages and restarting + daemons on all hosts: + + .. prompt:: bash # + + systemctl restart ceph-radosgw.target + +#. Complete the upgrade by disallowing pre-Quincy OSDs and enabling + all new Quincy-only functionality: + + .. prompt:: bash # + + ceph osd require-osd-release quincy + +#. If you set ``noout`` at the beginning, be sure to clear it with: + + .. prompt:: bash # + + ceph osd unset noout + +#. Consider transitioning your cluster to use the cephadm deployment + and orchestration framework to simplify cluster management and + future upgrades. For more information on converting an existing + cluster to cephadm, see :ref:`cephadm-adoption`. + +Post-upgrade +~~~~~~~~~~~~ + +#. Verify the cluster is healthy with ``ceph health``. If your cluster is + running Filestore, a deprecation warning is expected. This warning can + be temporarily muted using the following command: + + .. prompt:: bash # + + ceph health mute OSD_FILESTORE + +#. If you are upgrading from Mimic, or did not already do so when you + upgraded to Nautilus, we recommend you enable the new :ref:`v2 + network protocol <msgr2>`, issue the following command: + + .. prompt:: bash # + + ceph mon enable-msgr2 + + This will instruct all monitors that bind to the old default port + 6789 for the legacy v1 protocol to also bind to the new 3300 v2 + protocol port.
