+Ceph daemon control
+===================
+
+Starting and stopping daemons
+-----------------------------
+
+You can stop, start, or restart a daemon with:
+
+.. prompt:: bash #
+
+   ceph orch daemon stop <name>
+   ceph orch daemon start <name>
+   ceph orch daemon restart <name>
+
+You can also do the same for all daemons for a service with:   
+
+.. prompt:: bash #
+
+   ceph orch stop <name>
+   ceph orch start <name>
+   ceph orch restart <name>
+
+
+Redeploying or reconfiguring a daemon
+-------------------------------------
+
+The container for a daemon can be stopped, recreated, and restarted with
+the ``redeploy`` command:
+
+.. prompt:: bash #
+
+   ceph orch daemon redeploy <name> [--image <image>]
+
+A container image name can optionally be provided to force a
+particular image to be used (instead of the image specified by the
+``container_image`` config value).
+
+If only the ceph configuration needs to be regenerated, you can also
+issue a ``reconfig`` command, which will rewrite the ``ceph.conf``
+file but will not trigger a restart of the daemon.
+
+.. prompt:: bash #
+
+   ceph orch daemon reconfig <name>
