+====================================
+ Mount CephFS with the Kernel Driver
+====================================
+
+To mount the Ceph file system you may use the ``mount`` command if you know the
+monitor host IP address(es), or use the ``mount.ceph`` utility to resolve the 
+monitor host name(s) into IP address(es) for you. For example:: 
+
+	sudo mkdir /mnt/mycephfs
+	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs
+
+To mount the Ceph file system with ``cephx`` authentication enabled, the kernel
+must authenticate with the cluster. The default ``name=`` option is ``guest``.
+The mount.ceph helper will automatically attempt to find a secret key in the
+keyring.
+
+The secret can also be specified manually with the ``secret=`` option. ::
+
+	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secret=AQATSKdNGBnwLhAAnNDKnH65FmVKpXZJVasUeQ==
+
+The foregoing usage leaves the secret in the Bash history. A more secure
+approach reads the secret from a file. For example::
+
+	sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secretfile=/etc/ceph/admin.secret
+
+See `User Management`_ for details on cephx.
+	
+If you have more than one file system, specify which one to mount using
+the ``mds_namespace`` option, e.g. ``-o mds_namespace=myfs``.
+
+To unmount the Ceph file system, you may use the ``umount`` command. For example:: 
+
+	sudo umount /mnt/mycephfs
+
+.. tip:: Ensure that you are not within the file system directories before
+   executing this command.
+
+See `mount.ceph`_ for details.
