v15.2.8 Octopus released

This is the 8th backport release in the Octopus series. This release fixes a security flaw in CephFS and includes a number of bug fixes. We recommend users to update to this release.

Notable Changes

  • CVE-2020-27781 : OpenStack Manila use of ceph_volume_client.py library allowed tenant access to any Ceph credential’s secret. (Kotresh Hiremath Ravishankar, Ramana Raja)

  • ceph-volume: The lvm batch subcommand received a major rewrite. This closed a number of bugs and improves usability in terms of size specification and calculation, as well as idempotency behaviour and disk replacement process. Please refer to https://docs.ceph.com/en/latest/ceph-volume/lvm/batch/ for more detailed information.

  • MON: The cluster log now logs health detail every mon_health_to_clog_interval, which has been changed from 1hr to 10min. Logging of health detail will be skipped if there is no change in health summary since last known.

  • The ceph df command now lists the number of pgs in each pool.

  • The bluefs_preextend_wal_files option has been removed.

  • It is now possible to specify the initial monitor to contact for Ceph tools and daemons using the mon_host_override config option or --mon-host-override command-line switch. This generally should only be used for debugging and only affects initial communication with Ceph’s monitor cluster.
