15.2.9 ------ * MGR: progress module can now be turned on/off, using the commands: ``ceph progress on`` and ``ceph progress off``. * New bluestore_rocksdb_options_annex config parameter. Complements bluestore_rocksdb_options and allows setting rocksdb options without repeating the existing defaults. 15.2.8 ------ * $pid expansion in config paths like `admin_socket` will now properly expand to the daemon pid for commands like `ceph-mds` or `ceph-osd`. Previously only `ceph-fuse`/`rbd-nbd` expanded `$pid` with the actual daemon pid. * 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.
