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.
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.
