Ceph FS

The Ceph FS file system is a POSIX-compliant file system that uses a Ceph Storage Cluster to store its data. Ceph FS uses the same Ceph Storage Cluster system as Ceph Block Devices, Ceph Object Storage with its S3 and Swift APIs, or native bindings (librados).

Using Ceph FS requires at least one Ceph Metadata Server in your Ceph Storage Cluster.

Step 1: Metadata Server To run Ceph FS, you must have a running Ceph Storage Cluster with at least one Ceph Metadata Server running. Add/Remove MDS MDS Configuration Journaler Configuration Manpage ceph-mds
