 Maintenance Mode
 ================
 
-Place a host in and out of maintenance mode (stops all Ceph daemons on host):
+Putting a host into "maintenance mode" stops all Ceph daemons on the host. Run
+a command of the following form to put a host into maintenance mode or to take
+a host out of maintenance mode: 
 
 .. prompt:: bash #
 
    ceph orch host maintenance enter <hostname> [--force] [--yes-i-really-mean-it]
    ceph orch host maintenance exit <hostname> [--force] [--offline]
 
-The ``--force`` flag on the ``enter`` command allows the user to bypass warnings (but not alerts).
-The ``--yes-i-really-mean-it`` flag bypasses all safety checks and will attempt to force the
-host into maintenance mode no matter what. The ``--force`` and ``--offline`` flags to the ``exit`` command
-can be used to to have cephadm mark a host that is in maintenance mode and offline as no longer
-in maintenance mode. Note in this case if the host comes online, the Ceph daemons
-on the host will remain in the stopped state. The ``--force`` and ``--offline`` flags to the ``exit``
-command are intended to be run for hosts in maintenance mode that are permanently offline
-before removing the host entirely from cephadm management using the ``ceph orch host rm`` command.

-.. warning:: Using the --yes-i-really-mean-it flag to force the host to enter maintenance
-   mode can potentially cause loss of data availability, the mon quorum to break down due
-   to too few running monitors, mgr module commands (such as ``ceph orch . . .`` commands)
-   to be become unresponsive, and a number of other possible issues. Please only use this
-   flag if you're absolutely certain you know what you're doing.
