================
-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:
+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]
-* Adding the ``--force`` flag to the ``enter`` command allows the user to bypass
- warnings (but not alerts).
-* Adding the ``--yes-i-really-mean-it`` flag to the ``enter`` command bypasses
- all safety checks and makes an attempt to force the host into maintenance
- mode.
-* Adding the ``--force`` and ``--offline`` flags to the ``exit`` command cause
- cephadm to mark hosts that are in maintenance mode and offline as no longer
- in maintenance mode. Note that if the host comes online, the Ceph daemons on
- the host will remain in the stopped state. The ``--force`` and ``--offline``
- flags of the ``exit`` command are meant to be run on hosts that are in
- maintenance mode and that are permanently offline prior to the removal of
- those hosts from cephadm management by running the ``ceph orch host rm``
- command.

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