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).

Using CephFS
|
|
|
|
|
============
|
|
|
|
|
|
2013-05-31 03:28:22 +00:00
|
|
|
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.

|
Once you have a healthy Ceph Storage Cluster with at least
|
2014-08-18 15:57:25 +00:00
|
|
|
one Ceph Metadata Server, you may create and mount your Ceph Filesystem.
|
2013-05-17 22:56:59 +00:00
|
|
|
Ensure that you client has network connectivity and the proper
|
|
|
|
|
authentication keyring.
