3 * MGR: progress module can now be turned on/off, using the commands:
4 ``ceph progress on`` and ``ceph progress off``.
6 * New bluestore_rocksdb_options_annex config parameter. Complements
7 bluestore_rocksdb_options and allows setting rocksdb options without repeating
12 * $pid expansion in config paths like `admin_socket` will now properly expand
13 to the daemon pid for commands like `ceph-mds` or `ceph-osd`. Previously only
14 `ceph-fuse`/`rbd-nbd` expanded `$pid` with the actual daemon pid.
16 * ceph-volume: The ``lvm batch` subcommand received a major rewrite. This closed
17 a number of bugs and improves usability in terms of size specification and
18 calculation, as well as idempotency behaviour and disk replacement process.
19 Please refer to https://docs.ceph.com/en/latest/ceph-volume/lvm/batch/ for
20 more detailed information.
22 * MON: The cluster log now logs health detail every ``mon_health_to_clog_interval``,
23 which has been changed from 1hr to 10min. Logging of health detail will be
24 skipped if there is no change in health summary since last known.
26 * The ``ceph df`` command now lists the number of pgs in each pool.
28 * The ``bluefs_preextend_wal_files`` option has been removed.
30 * It is now possible to specify the initial monitor to contact for Ceph tools
31 and daemons using the ``mon_host_override`` config option or
32 ``--mon-host-override <ip>`` command-line switch. This generally should only
33 be used for debugging and only affects initial communication with Ceph's
