The :term:`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 :term:`Ceph Metadata Server` in your
|
|
|
|
|
Ceph Storage Cluster.

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

|
|
|
|
|
|
|
|
|
Once you have a healthy Ceph Storage Cluster with at least
|
|
|
|
|
one Ceph Metadata Server, you may mount your Ceph FS filesystem.
|
|
|
|
|
Ensure that you client has network connectivity and the proper
|
|
|
|
|
authentication keyring.
