v18.2.8 Reef released

This is the eighth, and expected to be last, backport release in the Reef series. We recommend that all users update to this release.

Release Date ¶

March 20, 2026

Known Issues ¶

• During QA for v18.2.8, it was found that there was a bug for upgrades from Pacific to Reef. Pacific OSDs (and other Ceph daemons) were still using a deprecated connection feature bit that was adopted to indicate a Reef OSD. This can cause a OSD_UPGRADE_FINISHED warning before all OSDs are actually upgraded to Reef. There are no known issues associated with Pacific and Reef OSDs interoperating where Pacific OSDs are "advertising" Reef compatibility; however, out of an abundance of caution, we no longer recommend upgrading from Pacific to Reef directly.

Security Fixes ¶

• CephFS Client: A fix was merged to prohibit unprivileged users from modifying the sgid or suid bits on a file. Previously, unprivileged users were inadvertently permitted to set these bits if they were the sole bits being modified.

• Mgr Alerts: The SMTP SSL context was enforced in the mgr/alerts module to resolve a security vulnerability (GHSA-xj9f-7g59-m4jx).

Notable Changes ¶

• RGW (RADOS Gateway):

  • Fixed an issue where bucket rm --bypass-gc was mistakenly removing head objects instead of tail objects, potentially causing data inconsistencies.
  • Fixed rgw-restore-bucket-index to handle objects with leading hyphens and to process versioned buckets correctly.
  • Addressed an issue in the msg/async protocol that caused memory locks and hangs during connection shutdown.
  • RGW STS: Made JWKS URL verification configurable for AWS compliance via the rgw_enable_jwks_url_verification configuration.

• CephFS / MDS:

  • Prevented the MDS from stalling (up to 5 seconds) during rename/stat workloads by forcing the log to nudge for unstable locks after early replies.
  • Fixed cephfs-journal-tool so it no longer incorrectly resets the journal trim position during disaster recovery, which was causing stale journal objects to linger forever in the metadata pool.
  • Fixed a bug where ll_walk incorrectly processed absolute paths as relative paths.
  • Prevented the ceph fs volume create command from accidentally deleting user-created pools if the command aborted during cleanup.
  • MDS Batched Operations: Added a new mds_allow_batched_ops configuration option (default: true) to control whether the MDS can batch lookup or getattr RPCs.
  • CephFS Subvolumes: Added the ceph fs subvolume snapshot getpath command to allow users to retrieve the absolute path of a snapshot of a subvolume.

• BlueStore:

  • Fixed a bug where the bytes_written_slow performance counter incorrectly reported 0 when using aio_write.
