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

| Ceph FS Library (libcephfs) |

+---------------------------------------------------+
| Ceph Storage Cluster Protocol (librados) |
+---------------------------------------------------+

| OSDs | | MDSs | | Monitors |
+---------------+ +---------------+ +---------------+
Using the Ceph Filesystem requires at least one :term:`Ceph Metadata Server` in
your Ceph Storage Cluster.

To run the Ceph Filesystem, you must have a running Ceph Storage Cluster with at
least one :term:`Ceph Metadata Server` running.

</td><td><h3>Step 2: Mount Ceph FS</h3>
Once you have a healthy Ceph Storage Cluster with at least
one Ceph Metadata Server, you may mount your Ceph Filesystem.
Ensure that you client has network connectivity and the proper
authentication keyring.
