+=====================
+ Operating a Cluster
+=====================
+
+The ``ceph`` service provides functionality to **start**, **restart**, and
+**stop** your Ceph cluster. Each time you execute ``ceph`` processes, you
+must specify at least one option and one command. You may also specify a daemon
+type or a daemon instance. For most newer Debian/Ubuntu distributions, you may
+use the following syntax::
+
+ sudo service ceph [options] [commands] [daemons]
+
+For older distributions, you may wish to use the ``/etc/init.d/ceph`` path::
+
+ sudo /etc/init.d/ceph [options] [commands] [daemons]
+
+The ``ceph`` service options include:
+
++-----------------+----------+-------------------------------------------------+
+| Option | Shortcut | Description |
++=================+==========+=================================================+
+| ``--verbose`` | ``-v`` | Use verbose logging. |
++-----------------+----------+-------------------------------------------------+
+| ``--valgrind`` | ``N/A`` | (Developers only) Use `Valgrind`_ debugging. |
++-----------------+----------+-------------------------------------------------+
+| ``--allhosts`` | ``-a`` | Execute on all hosts in ``ceph.conf.`` |
+| | | Otherwise, it only executes on ``localhost``. |
++-----------------+----------+-------------------------------------------------+
+| ``--restart`` | ``N/A`` | Automatically restart daemon if it core dumps. |
++-----------------+----------+-------------------------------------------------+
+| ``--norestart`` | ``N/A`` | Don't restart a daemon if it core dumps. |
++-----------------+----------+-------------------------------------------------+
+| ``--conf`` | ``-c`` | Use an alternate configuration file. |
++-----------------+----------+-------------------------------------------------+
+
+The ``ceph`` service commands include:
+
++------------------+------------------------------------------------------------+
+| Command | Description |
++==================+============================================================+
+| ``start`` | Start the daemon(s). |
++------------------+------------------------------------------------------------+
+| ``stop`` | Stop the daemon(s). |
++------------------+------------------------------------------------------------+
+| ``forcestop`` | Force the daemon(s) to stop. Same as ``kill -9`` |
++------------------+------------------------------------------------------------+
+| ``killall`` | Kill all daemons of a particular type. |
++------------------+------------------------------------------------------------+
+| ``cleanlogs`` | Cleans out the log directory. |
++------------------+------------------------------------------------------------+
+| ``cleanalllogs`` | Cleans out **everything** in the log directory. |
++------------------+------------------------------------------------------------+
+
+For subsystem operations, the ``ceph`` service can target specific daemon types by
+adding a particular daemon type for the ``[daemons]`` option. Daemon types include:
+
+- ``mon``
+- ``osd``
+- ``mds``
+
+The ``ceph`` service's ``[daemons]`` setting may also target a specific instance::
+
+ sudo /etc/init.d/ceph -a start osd.0
+
+Where ``osd.0`` is the first OSD in the cluster.
+
+
+Starting a Cluster
+------------------
+
+To start your Ceph cluster, execute ``ceph`` with the ``start`` command.
+The usage may differ based upon your Linux distribution. For example, for most
+newer Debian/Ubuntu distributions, you may use the following syntax::
+
+ sudo service ceph start [options] [start|restart] [daemonType|daemonID]
+
+For older distributions, you may wish to use the ``/etc/init.d/ceph`` path::
+
+ sudo /etc/init.d/ceph [options] [start|restart] [daemonType|daemonID]
+
+The following examples illustrates a typical use case::
+
+ sudo service ceph -a start
+ sudo /etc/init.d/ceph -a start
+
+Once you execute with ``-a``, Ceph should begin operating. You may also specify
+a particular daemon instance to constrain the command to a single instance. For
+example::
+
+ sudo /etc/init.d/ceph start osd.0
+
+
+Stopping a Cluster
+------------------
+
+To stop your Ceph cluster, execute ``ceph`` with the ``stop`` command.
+The usage may differ based upon your Linux distribution. For example, for most
+newer Debian/Ubuntu distributions, you may use the following syntax::
+
+ sudo service ceph [options] stop [daemonType|daemonID]
+
+For example::
+
+ sudo service -a ceph stop
+
+For older distributions, you may wish to use the ``/etc/init.d/ceph`` path::
+
+ sudo /etc/init.d/ceph -a stop
+
+Ceph should shut down the operating processes.
