+Adding a data pool to the MDS
+---------------------------------
+
+Before you can use a pool with CephFS you have to add it to the Metadata Servers.
+
+.. code-block:: bash
+
+    $ ceph mds add_data_pool cephfs_data_ssd
+    # Pool should now show up
+    $ ceph fs ls
+    .... data pools: [cephfs_data cephfs_data_ssd ]
+
+Make sure that your cephx keys allows the client to access this new pool.
