Doc Type: Enhancement
Doc Text:
.Ceph File System (CephFS) now provides a configuration option for MDS called `mds_join_fs` With this release, when failing over metadata server (MDS) daemons, the cluster’s monitors prefer standby daemons with `mds_join_fs` equal to the file system name with the failed `rank`. If no standby exists with `mds_join_fs` equal to the file system `name`, it chooses an unqualified standby for the replacement, or any other available standby, as a last resort. See the link:{cephfs-guide}#file-system-affinity_fs[_File system affinity_] section in the _{storage-product} File System Guide_ for more information.
