.The Ceph File System (CephFS) and Metadata Server (MDS)
The Ceph File System (CephFS) and Ceph Metadata Server (MDS) have been added as Technology Preview features.
The Ceph File System is a POSIX-compliant file system that uses the Ceph Storage Cluster to store its data. CephFS can be mounted with a kernel driver or as a file system in user space (FUSE).
The Ceph Metadata Server manages metadata related to files stored on the Ceph File System. The MDS daemon (`ceph-mds`) also coordinates access to the shared cluster.
In addition, the CephFS repair utilities are now supported.
