[Ceph-announce] v14.2.12 Nautilus released

This is the 12th backport release in the Nautilus series. This release brings a number of bugfixes across all major components of Ceph. We recommend that all Nautilus users upgrade to this release. For a detailed release notes with links & changelog please refer to the official blog entry at https://ceph.io/releases/v14-2-12-nautilus-released Notable Changes --------------- * The `ceph df` command now lists the number of pgs in each pool. * Monitors now have a config option `mon_osd_warn_num_repaired`, 10 by default. If any OSD has repaired more than this many I/O errors in stored data a `OSD_TOO_MANY_REPAIRS` health warning is generated. In order to allow clearing of the warning, a new command `ceph tell osd.# clear_shards_repaired [count]` has been added. By default it will set the repair count to 0. If you wanted to be warned again if additional repairs are performed you can provide a value to the command and specify the value of `mon_osd_warn_num_repaired`. This command will be replaced in future releases by the health mute/unmute feature. * 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.
