Mount Ceph FS using FUSE
=========================
Before mounting a Ceph File System in User Space (FUSE), ensure that the client
host has a copy of the Ceph configuration file and a keyring with CAPS for the
Ceph metadata server.
#. From your client host, copy the Ceph configuration file from the monitor host
to the ``/etc/ceph`` directory. ::
sudo mkdir -p /etc/ceph
sudo scp {user}@{server-machine}:/etc/ceph/ceph.conf /etc/ceph/ceph.conf
#. From your client host, copy the Ceph keyring from the monitor host to
to the ``/etc/ceph`` directory. ::
sudo scp {user}@{server-machine}:/etc/ceph/ceph.keyring /etc/ceph/ceph.keyring
#. Ensure that the Ceph configuration file and the keyring have appropriate
permissions set on your client machine (e.g., ``chmod 644``).
For additional details on ``cephx`` configuration, see
`CEPHX Config Reference`_.
To mount the Ceph file system as a FUSE, you may use the ``ceph-fuse`` command.
For example::
sudo mkdir /home/usernname/cephfs
sudo ceph-fuse -m 192.168.0.1:6789 /home/username/cephfs
If you have more than one filesystem, specify which one to mount using
the ``--client_mds_namespace`` command line argument, or add a
``client_mds_namespace`` setting to your ``ceph.conf``.
See `ceph-fuse`_ for additional details.
To automate mounting ceph-fuse, you may add an entry to the system fstab_.
Additionally, ``ceph-fuse@.service`` and ``ceph-fuse.target`` systemd units are
available. As usual, these unit files declare the default dependencies and
recommended execution context for ``ceph-fuse``. An example ceph-fuse mount on
``/mnt`` would be::
sudo systemctl start ceph-fuse@/mnt.service
A persistent mount point can be setup via::
sudo systemctl enable ceph-fuse@/mnt.service

.. _fstab: ./fstab
