[ceph-users] v15.2.8 Octopus released

We're happy to announce 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. For a detailed release notes with links & changelog please refer to the official blog entry at https://ceph.io/releases/v15-2-8-octopus-released 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 <ip>` command-line switch. This generally should only be used for debugging and only affects initial communication with Ceph's monitor cluster.
