====================================
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.
