Squid

Squid is the 19th stable release of Ceph.

v19.2.3 Squid

This is the third backport release in the Squid series. We recommend that all users update to this release.

Notable Changes

• RGW: PutObjectLockConfiguration can now be used to enable S3 Object Lock on an existing versioning-enabled bucket that was not created with Object Lock enabled.

• RADOS: A new command, ceph osd rm-pg-upmap-primary-all, has been added that allows users to clear all pg-upmap-primary mappings in the osdmap when desired. Related trackers:

  • https://tracker.ceph.com/issues/67179

  • https://tracker.ceph.com/issues/66867

• RBD: Moving an image that is a member of a group to trash is no longer allowed. rbd trash mv command now behaves the same way as rbd rm in this scenario.

• MGR: MGR’s always-on modulues/plugins can now be force-disabled. This can be necessary in cases where MGR(s) needs to be prevented from being flooded by the module commands when coresponding Ceph service is down/degraded.

• RGW: An authentication bypass vulnerability in STS [CVE-2023-43040] has been fixed.

• RGW: S3 policy now enforces ARN-based conditionals.

• RGW: Copying an object to itself no longer causes data loss. Potential corruption on ETIMEDOUT (not enabled by default), was also fixed.

v19.2.2 Squid

This is the second hotfix release in the Squid series. We recommend that all users update to this release.

Notable Changes

• This hotfix release resolves an RGW data loss bug when CopyObject is used to copy an object onto itself. S3 clients typically do this when they want to change the metadata of an existing object. Due to a regression caused by an earlier fix for https://tracker.ceph.com/issues/66286, any tail objects associated with such objects are erroneously marked for garbage collection. RGW deployments on Squid are encouraged to upgrade as soon as possible to minimize the damage. The experimental rgw-gap-list tool can help to identify damaged objects.

Changelog

• squid: rgw: keep the tails when copying object to itself (pr#62711, cbodley)

v19.2.1 Squid

This is the first backport release in the Squid series.

Notable Changes

• CephFS: The command fs subvolume create now allows tagging subvolumes by supplying the option --earmark with a unique identifier needed for NFS or SMB services. The earmark string for a subvolume is empty by default. To remove an already present earmark, an empty string can be assigned to it. Additionally, the commands ceph fs subvolume earmark set, ceph fs subvolume earmark get, and ceph fs subvolume earmark rm have been added to set, get and remove earmark from a given subvolume.

• CephFS: Expanded removexattr support for CephFS virtual extended attributes. Previously one had to use setxattr to restore the default in order to “remove”. You may now properly use removexattr to remove. You can also now remove layout on the root inode, which then will restore the layout to the default.

• RADOS: A performance bottleneck in the balancer mgr module has been fixed.

  Related Tracker: https://tracker.ceph.com/issues/68657

• RADOS: Based on tests performed at scale on an HDD-based Ceph cluster, it was found that scheduling with mClock was not optimal with multiple OSD shards. For example, in the test cluster with multiple OSD node failures, the client throughput was found to be inconsistent across test runs coupled with multiple reported slow requests. However, the same test with a single OSD shard and with multiple worker threads yielded significantly better results in terms of consistency of client and recovery throughput across multiple test runs. Therefore, as an interim measure until the issue with multiple OSD shards (or multiple mClock queues per OSD) is investigated and fixed, the following change to the default HDD OSD shard configuration is made:

  • osd_op_num_shards_hdd = 1 (was 5)

  • osd_op_num_threads_per_shard_hdd = 5 (was 1)

  For more details, see https://tracker.ceph.com/issues/66289.

• mgr/REST: The REST manager module will trim requests based on the ‘max_requests’ option. Without this feature, and in the absence of manual deletion of old requests, the accumulation of requests in the array can lead to Out Of Memory (OOM) issues, resulting in the Manager crashing.

Changelog

• doc/rgw/notification: add missing admin commands (pr#60609, Yuval Lifshitz)

v19.2.0 Squid

Attention

iSCSI users are advised that the upstream developers of Ceph encountered a bug during an upgrade from Ceph 19.1.1 to Ceph 19.2.0. Read Tracker Issue 68215 before attempting an upgrade to 19.2.0.

Some users have encountered a Ceph Manager balancer module issue when upgrading to Ceph 19.2.0. If you encounter this issue, disable the balancer by running the command ceph balancer off and the cluster will operate as expected. A fix has been implemented in 19.2.1, please read Tracker Issue 68657 before attempting an upgrade.

Highlights

RADOS

• BlueStore has been optimized for better performance in snapshot-intensive workloads.

• BlueStore RocksDB LZ4 compression is now enabled by default to improve average performance and “fast device” space usage.

• Other improvements include more flexible EC configurations, an OpTracker to help debug mgr module issues, and better scrub scheduling.

Dashboard

• Improved navigation layout

• Support for managing CephFS snapshots and clones, as well as snapshot schedule management

• Manage authorization capabilities for CephFS resources

• Helpers on mounting a CephFS volume

RBD

• diff-iterate can now execute locally, bringing a dramatic performance improvement for QEMU live disk synchronization and backup use cases.

• Support for cloning from non-user type snapshots is added.

• rbd-wnbd driver has gained the ability to multiplex image mappings.

RGW

• The User Accounts feature unlocks several new AWS-compatible IAM APIs for the self-service management of users, keys, groups, roles, policy and more.

Crimson/Seastore

• Crimson’s first tech preview release! Supporting RBD workloads on Replicated pools. For more information please visit: https://ceph.io/en/news/crimson

Ceph

• ceph: a new --daemon-output-file switch is available for ceph tell commands to dump output to a file local to the daemon. For commands which produce large amounts of output, this avoids a potential spike in memory usage on the daemon, allows for faster streaming writes to a file local to the daemon, and reduces time holding any locks required to execute the command. For analysis, it is necessary to manually retrieve the file from the host running the daemon. Currently, only --format=json|json-pretty are supported.

• cls_cxx_gather is marked as deprecated.

• Tracing: The blkin tracing feature (see https://docs.ceph.com/en/reef/dev/blkin/) is now deprecated in favor of Opentracing (https://docs.ceph.com/en/reef/dev/developer_guide/jaegertracing/) and will be removed in a later release.

• PG dump: The default output of ceph pg dump --format json has changed. The default JSON format produces a rather massive output in large clusters and isn’t scalable, so we have removed the ‘network_ping_times’ section from the output. Details in the tracker: https://tracker.ceph.com/issues/57460

CephFS

• CephFS: it is now possible to pause write I/O and metadata mutations on a tree in the file system using a new suite of subvolume quiesce commands. This is implemented to support crash-consistent snapshots for distributed applications. Please see the relevant section in the documentation on CephFS subvolumes for more information.

• CephFS: MDS evicts clients which are not advancing their request tids which causes a large buildup of session metadata resulting in the MDS going read-only due to the RADOS operation exceeding the size threshold. mds_session_metadata_threshold config controls the maximum size that a (encoded) session metadata can grow.

• CephFS: A new “mds last-seen” command is available for querying the last time an MDS was in the FSMap, subject to a pruning threshold.

• CephFS: For clusters with multiple CephFS file systems, all the snap-schedule commands now expect the ‘--fs’ argument.

• CephFS: The period specifier m now implies minutes and the period specifier M now implies months. This has been made consistent with the rest of the system.

• CephFS: Running the command “ceph fs authorize” for an existing entity now upgrades the entity’s capabilities instead of printing an error. It can now also change read/write permissions in a capability that the entity already holds. If the capability passed by user is same as one of the capabilities that the entity already holds, idempotency is maintained.

• CephFS: Two FS names can now be swapped, optionally along with their IDs, using “ceph fs swap” command. The function of this API is to facilitate file system swaps for disaster recovery. In particular, it avoids situations where a named file system is temporarily missing which would prompt a higher level storage operator (like Rook) to recreate the missing file system. See https://docs.ceph.com/en/latest/cephfs/administration/#file-systems docs for more information.

• CephFS: Before running the command “ceph fs rename”, the filesystem to be renamed must be offline and the config “refuse_client_session” must be set for it. The config “refuse_client_session” can be removed/unset and filesystem can be online after the rename operation is complete.

• CephFS: Disallow delegating preallocated inode ranges to clients. Config mds_client_delegate_inos_pct defaults to 0 which disables async dirops in the kclient.

• CephFS: MDS log trimming is now driven by a separate thread which tries to trim the log every second (mds_log_trim_upkeep_interval config). Also, a couple of configs govern how much time the MDS spends in trimming its logs. These configs are mds_log_trim_threshold and mds_log_trim_decay_rate.

• CephFS: Full support for subvolumes and subvolume groups is now available

• CephFS: The subvolume snapshot clone command now depends on the config option snapshot_clone_no_wait which is used to reject the clone operation when all the cloner threads are busy. This config option is enabled by default which means that if no cloner threads are free, the clone request errors out with EAGAIN. The value of the config option can be fetched by using: ceph config get mgr mgr/volumes/snapshot_clone_no_wait and it can be disabled by using: ceph config set mgr mgr/volumes/snapshot_clone_no_wait false for snap_schedule Manager module.

• CephFS: Commands ceph mds fail and ceph fs fail now require a confirmation flag when some MDSs exhibit health warning MDS_TRIM or MDS_CACHE_OVERSIZED. This is to prevent accidental MDS failover causing further delays in recovery.

• CephFS: fixes to the implementation of the root_squash mechanism enabled via cephx mds caps on a client credential require a new client feature bit, client_mds_auth_caps. Clients using credentials with root_squash without this feature will trigger the MDS to raise a HEALTH_ERR on the cluster, MDS_CLIENTS_BROKEN_ROOTSQUASH. See the documentation on this warning and the new feature bit for more information.

• CephFS: Expanded removexattr support for cephfs virtual extended attributes. Previously one had to use setxattr to restore the default in order to “remove”. You may now properly use removexattr to remove. You can also now remove layout on root inode, which then will restore layout to default layout.

• CephFS: cephfs-journal-tool is guarded against running on an online file system. The ‘cephfs-journal-tool --rank <fs_name>:<mds_rank> journal reset’ and ‘cephfs-journal-tool --rank <fs_name>:<mds_rank> journal reset --force’ commands require ‘--yes-i-really-really-mean-it’.

• CephFS: “ceph fs clone status” command will now print statistics about clone progress in terms of how much data has been cloned (in both percentage as well as bytes) and how many files have been cloned.

• CephFS: “ceph status” command will now print a progress bar when cloning is ongoing. If clone jobs are more than the cloner threads, it will print one more progress bar that shows total amount of progress made by both ongoing as well as pending clones. Both progress are accompanied by messages that show number of clone jobs in the respective categories and the amount of progress made by each of them.

• cephfs-shell: The cephfs-shell utility is now packaged for RHEL 9 / CentOS 9 as required python dependencies are now available in EPEL9.

• The CephFS automatic metadata load (sometimes called “default”) balancer is now disabled by default. The new file system flag balance_automate can be used to toggle it on or off. It can be enabled or disabled via ceph fs set <fs_name> balance_automate <bool>.

CephX

• cephx: key rotation is now possible using ceph auth rotate. Previously, this was only possible by deleting and then recreating the key.

Dashboard

• Dashboard: Rearranged Navigation Layout: The navigation layout has been reorganized for improved usability and easier access to key features.

• Dashboard: CephFS Improvments * Support for managing CephFS snapshots and clones, as well as snapshot schedule management * Manage authorization capabilities for CephFS resources * Helpers on mounting a CephFS volume

• Dashboard: RGW Improvements * Support for managing bucket policies * Add/Remove bucket tags * ACL Management * Several UI/UX Improvements to the bucket form

MGR

• MGR/REST: The REST manager module will trim requests based on the ‘max_requests’ option. Without this feature, and in the absence of manual deletion of old requests, the accumulation of requests in the array can lead to Out Of Memory (OOM) issues, resulting in the Manager crashing.

• MGR: An OpTracker to help debug mgr module issues is now available.

Monitoring

• Monitoring: Grafana dashboards are now loaded into the container at runtime rather than building a grafana image with the grafana dashboards. Official Ceph grafana images can be found in quay.io/ceph/grafana

• Monitoring: RGW S3 Analytics: A new Grafana dashboard is now available, enabling you to visualize per bucket and user analytics data, including total GETs, PUTs, Deletes, Copies, and list metrics.

• The mon_cluster_log_file_level and mon_cluster_log_to_syslog_level options have been removed. Henceforth, users should use the new generic option mon_cluster_log_level to control the cluster log level verbosity for the cluster log file as well as for all external entities.

RADOS

• RADOS: A POOL_APP_NOT_ENABLED health warning will now be reported if the application is not enabled for the pool irrespective of whether the pool is in use or not. Always tag a pool with an application using ceph osd pool application enable command to avoid reporting of POOL_APP_NOT_ENABLED health warning for that pool. The user might temporarily mute this warning using ceph health mute POOL_APP_NOT_ENABLED.

• RADOS: get_pool_is_selfmanaged_snaps_mode C++ API has been deprecated due to being prone to false negative results. Its safer replacement is pool_is_in_selfmanaged_snaps_mode.

• RADOS: For bug 62338 (https://tracker.ceph.com/issues/62338), we did not choose to condition the fix on a server flag in order to simplify backporting. As a result, in rare cases it may be possible for a PG to flip between two acting sets while an upgrade to a version with the fix is in progress. If you observe this behavior, you should be able to work around it by completing the upgrade or by disabling async recovery by setting osd_async_recovery_min_cost to a very large value on all OSDs until the upgrade is complete: ceph config set osd osd_async_recovery_min_cost 1099511627776

• RADOS: A detailed version of the balancer status CLI command in the balancer module is now available. Users may run ceph balancer status detail to see more details about which PGs were updated in the balancer’s last optimization. See https://docs.ceph.com/en/latest/rados/operations/balancer/ for more information.

• RADOS: Read balancing may now be managed automatically via the balancer manager module. Users may choose between two new modes: upmap-read, which offers upmap and read optimization simultaneously, or read, which may be used to only optimize reads. For more detailed information see https://docs.ceph.com/en/latest/rados/operations/read-balancer/#online-optimization.

• RADOS: BlueStore has been optimized for better performance in snapshot-intensive workloads.

• RADOS: BlueStore RocksDB LZ4 compression is now enabled by default to improve average performance and “fast device” space usage.

• RADOS: A new CRUSH rule type, MSR (Multi-Step Retry), allows for more flexible EC configurations.

• RADOS: Scrub scheduling behavior has been improved.

Crimson/Seastore

• Crimson’s first tech preview release! Supporting RBD workloads on Replicated pools. For more information please visit: https://ceph.io/en/news/crimson

RBD

• RBD: When diffing against the beginning of time (fromsnapname == NULL) in fast-diff mode (whole_object == true with fast-diff image feature enabled and valid), diff-iterate is now guaranteed to execute locally if exclusive lock is available. This brings a dramatic performance improvement for QEMU live disk synchronization and backup use cases.

• RBD: The try-netlink mapping option for rbd-nbd has become the default and is now deprecated. If the NBD netlink interface is not supported by the kernel, then the mapping is retried using the legacy ioctl interface.

• RBD: The option --image-id has been added to rbd children CLI command, so it can be run for images in the trash.

• RBD: Image::access_timestamp and Image::modify_timestamp Python APIs now return timestamps in UTC.

• RBD: Support for cloning from non-user type snapshots is added. This is intended primarily as a building block for cloning new groups from group snapshots created with rbd group snap create command, but has also been exposed via the new --snap-id option for rbd clone command.

• RBD: The output of rbd snap ls --all command now includes the original type for trashed snapshots.

• RBD: RBD_IMAGE_OPTION_CLONE_FORMAT option has been exposed in Python bindings via clone_format optional parameter to clone, deep_copy and migration_prepare methods.

• RBD: RBD_IMAGE_OPTION_FLATTEN option has been exposed in Python bindings via flatten optional parameter to deep_copy and migration_prepare methods.

• RBD: rbd-wnbd driver has gained the ability to multiplex image mappings. Previously, each image mapping spawned its own rbd-wnbd daemon, which lead to an excessive amount of TCP sessions and other resources being consumed, eventually exceeding Windows limits. With this change, a single rbd-wnbd daemon is spawned per host and most OS resources are shared between image mappings. Additionally, ceph-rbd service starts much faster.

RGW

• RGW: GetObject and HeadObject requests now return a x-rgw-replicated-at header for replicated objects. This timestamp can be compared against the Last-Modified header to determine how long the object took to replicate.

• RGW: S3 multipart uploads using Server-Side Encryption now replicate correctly in multi-site. Previously, the replicas of such objects were corrupted on decryption. A new tool, radosgw-admin bucket resync encrypted multipart, can be used to identify these original multipart uploads. The LastModified timestamp of any identified object is incremented by 1ns to cause peer zones to replicate it again. For multi-site deployments that make any use of Server-Side Encryption, we recommended running this command against every bucket in every zone after all zones have upgraded.

• RGW: Introducing a new data layout for the Topic metadata associated with S3 Bucket Notifications, where each Topic is stored as a separate RADOS object and the bucket notification configuration is stored in a bucket attribute. This new representation supports multisite replication via metadata sync and can scale to many topics. This is on by default for new deployments, but is not enabled by default on upgrade. Once all radosgws have upgraded (on all zones in a multisite configuration), the notification_v2 zone feature can be enabled to migrate to the new format. See https://docs.ceph.com/en/squid/radosgw/zone-features for details. The “v1” format is now considered deprecated and may be removed after 2 major releases.

• RGW: New tools have been added to radosgw-admin for identifying and correcting issues with versioned bucket indexes. Historical bugs with the versioned bucket index transaction workflow made it possible for the index to accumulate extraneous “book-keeping” olh entries and plain placeholder entries. In some specific scenarios where clients made concurrent requests referencing the same object key, it was likely that a lot of extra index entries would accumulate. When a significant number of these entries are present in a single bucket index shard, they can cause high bucket listing latencies and lifecycle processing failures. To check whether a versioned bucket has unnecessary olh entries, users can now run radosgw-admin bucket check olh. If the --fix flag is used, the extra entries will be safely removed. A distinct issue from the one described thus far, it is also possible that some versioned buckets are maintaining extra unlinked objects that are not listable from the S3/ Swift APIs. These extra objects are typically a result of PUT requests that exited abnormally, in the middle of a bucket index transaction - so the client would not have received a successful response. Bugs in prior releases made these unlinked objects easy to reproduce with any PUT request that was made on a bucket that was actively resharding. Besides the extra space that these hidden, unlinked objects consume, there can be another side effect in certain scenarios, caused by the nature of the failure mode that produced them, where a client of a bucket that was a victim of this bug may find the object associated with the key to be in an inconsistent state. To check whether a versioned bucket has unlinked entries, users can now run radosgw-admin bucket check unlinked. If the --fix flag is used, the unlinked objects will be safely removed. Finally, a third issue made it possible for versioned bucket index stats to be accounted inaccurately. The tooling for recalculating versioned bucket stats also had a bug, and was not previously capable of fixing these inaccuracies. This release resolves those issues and users can now expect that the existing radosgw-admin bucket check command will produce correct results. We recommend that users with versioned buckets, especially those that existed on prior releases, use these new tools to check whether their buckets are affected and to clean them up accordingly.

• RGW: The User Accounts feature unlocks several new AWS-compatible IAM APIs for the self-service management of users, keys, groups, roles, policy and more. Existing users can be adopted into new accounts. This process is optional but irreversible. See https://docs.ceph.com/en/squid/radosgw/account and https://docs.ceph.com/en/squid/radosgw/iam for details.

• RGW: On startup, radosgw and radosgw-admin now validate the rgw_realm config option. Previously, they would ignore invalid or missing realms and go on to load a zone/zonegroup in a different realm. If startup fails with a “failed to load realm” error, fix or remove the rgw_realm option.

• RGW: The radosgw-admin commands realm create and realm pull no longer set the default realm without --default.

• RGW: Fixed an S3 Object Lock bug with PutObjectRetention requests that specify a RetainUntilDate after the year 2106. This date was truncated to 32 bits when stored, so a much earlier date was used for object lock enforcement. This does not effect PutBucketObjectLockConfiguration where a duration is given in Days. The RetainUntilDate encoding is fixed for new PutObjectRetention requests, but cannot repair the dates of existing object locks. Such objects can be identified with a HeadObject request based on the x-amz-object-lock-retain-until-date response header.

• S3 Get/HeadObject now supports the query parameter partNumber to read a specific part of a completed multipart upload.

• RGW: The SNS CreateTopic API now enforces the same topic naming requirements as AWS: Topic names must be made up of only uppercase and lowercase ASCII letters, numbers, underscores, and hyphens, and must be between 1 and 256 characters long.

• RGW: Notification topics are now owned by the user that created them. By default, only the owner can read/write their topics. Topic policy documents are now supported to grant these permissions to other users. Preexisting topics are treated as if they have no owner, and any user can read/write them using the SNS API. If such a topic is recreated with CreateTopic, the issuing user becomes the new owner. For backward compatibility, all users still have permission to publish bucket notifications to topics owned by other users. A new configuration parameter, rgw_topic_require_publish_policy, can be enabled to deny sns:Publish permissions unless explicitly granted by topic policy.

• RGW: Fix issue with persistent notifications where the changes to topic param that were modified while persistent notifications were in the queue will be reflected in notifications. So if the user sets up topic with incorrect config (password/ssl) causing failure while delivering the notifications to broker, can now modify the incorrect topic attribute and on retry attempt to delivery the notifications, new configs will be used.

• RGW: in bucket notifications, the principalId inside ownerIdentity now contains the complete user ID, prefixed with the tenant ID.

Telemetry

• The basic channel in telemetry now captures pool flags that allows us to better understand feature adoption, such as Crimson. To opt in to telemetry, run ceph telemetry on.

Upgrading from Quincy or Reef

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,

ceph orch upgrade start --image quay.io/ceph/ceph:v19.2.0

The same process is used to upgrade to future minor releases.

Upgrade progress can be monitored with

ceph orch upgrade status

Upgrade progress can also be monitored with ceph -s (which provides a simple progress bar) or more verbosely with

ceph -W cephadm

The upgrade can be paused or resumed with

ceph orch upgrade pause  # to pause
ceph orch upgrade resume # to resume

or canceled with

ceph orch upgrade stop

Note that canceling the upgrade simply stops the process; there is no ability to downgrade back to Quincy or Reef.

Upgrading non-cephadm clusters

Note

1. If your cluster is running Quincy (17.2.x) or later, you might choose to first convert it to use cephadm so that the upgrade to Squid is automated (see above). For more information, see https://docs.ceph.com/en/squid/cephadm/adoption/.

2. If your cluster is running Quincy (17.2.x) or later, systemd unit file names have changed to include the cluster fsid. To find the correct systemd unit file name for your cluster, run following command:

   systemctl -l | grep <daemon type>
   

   Example:

   systemctl -l | grep mon | grep active
   

   ceph-6ce0347c-314a-11ee-9b52-000af7995d6c@mon.f28-h21-000-r630.service                                           loaded active running   Ceph mon.f28-h21-000-r630 for 6ce0347c-314a-11ee-9b52-000af7995d6c
   

1. Set the noout flag for the duration of the upgrade. (Optional, but recommended.)

   ceph osd set noout
   

2. Upgrade monitors by installing the new packages and restarting the monitor daemons. For example, on each monitor host

   systemctl restart ceph-mon.target
   

   Once all monitors are up, verify that the monitor upgrade is complete by looking for the squid string in the mon map. The command

   ceph mon dump | grep min_mon_release
   

   should report:

   min_mon_release 19 (squid)
   

   If it does not, that implies that one or more monitors hasn’t been upgraded and restarted and/or the quorum does not include all monitors.

3. Upgrade ceph-mgr daemons by installing the new packages and restarting all manager daemons. For example, on each manager host,

   systemctl restart ceph-mgr.target
   

   Verify the ceph-mgr daemons are running by checking ceph -s:

   ceph -s
   

   ...
     services:
      mon: 3 daemons, quorum foo,bar,baz
      mgr: foo(active), standbys: bar, baz
   ...
   

4. Upgrade all OSDs by installing the new packages and restarting the ceph-osd daemons on all OSD hosts

   systemctl restart ceph-osd.target
   

5. Upgrade all CephFS MDS daemons. For each CephFS file system,

   1. Disable standby_replay:

      ceph fs set <fs_name> allow_standby_replay false
      

   2. Reduce the number of ranks to 1. (Make note of the original number of MDS daemons first if you plan to restore it later.)

      ceph status # ceph fs set <fs_name> max_mds 1
      

   3. Wait for the cluster to deactivate any non-zero ranks by periodically checking the status

      ceph status
      

   4. Take all standby MDS daemons offline on the appropriate hosts with

      systemctl stop ceph-mds@<daemon_name>
      

   5. Confirm that only one MDS is online and is rank 0 for your FS

      ceph status
      

   6. Upgrade the last remaining MDS daemon by installing the new packages and restarting the daemon

      systemctl restart ceph-mds.target
      

   7. Restart all standby MDS daemons that were taken offline

      systemctl start ceph-mds.target
      

   8. Restore the original value of max_mds for the volume

      ceph fs set <fs_name> max_mds <original_max_mds>
      

6. Upgrade all radosgw daemons by upgrading packages and restarting daemons on all hosts

   systemctl restart ceph-radosgw.target
   

7. Complete the upgrade by disallowing pre-Squid OSDs and enabling all new Squid-only functionality

   ceph osd require-osd-release squid
   

8. If you set noout at the beginning, be sure to clear it with

   ceph osd unset noout
   

9. 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 https://docs.ceph.com/en/squid/cephadm/adoption/.

Post-upgrade

1. Verify the cluster is healthy with ceph health. If your cluster is running Filestore, and you are upgrading directly from Quincy to Squid, a deprecation warning is expected. This warning can be temporarily muted using the following command

   ceph health mute OSD_FILESTORE
   

2. Consider enabling the telemetry module to send anonymized usage statistics and crash information to the Ceph upstream developers. To see what would be reported (without actually sending any information to anyone),

   ceph telemetry preview-all
   

   If you are comfortable with the data that is reported, you can opt-in to automatically report the high-level cluster metadata with

   ceph telemetry on
   

   The public dashboard that aggregates Ceph telemetry can be found at https://telemetry-public.ceph.com/.

Upgrading from pre-Quincy releases (like Pacific)

You must first upgrade to Quincy (17.2.z) or Reef (18.2.z) before upgrading to Squid.
