you execute ``ceph health`` or ``ceph -s`` on the command line and Ceph returns
a health status, the return of a status means that the monitors have a quorum.
If you don't have a monitor quorum or if there are errors with the monitor
-status, address the monitor issues first. Check your networks to ensure they
+status, `address the monitor issues first <../troubleshooting-mon>`_.
+Check your networks to ensure they
are running properly, because networks may have a significant impact on OSD
operation and performance.
Once the cluster is set to ``noout``, you can begin stopping the OSDs within the
failure domain that requires maintenance work. ::
- ceph osd stop osd.{num}
+ stop ceph-osd id={num}
.. note:: Placement groups within the OSDs you stop will become ``degraded``
while you are addressing issues with within the failure domain.
Once you have completed your maintenance, restart the OSDs. ::
- ceph osd start osd.{num}
+ start ceph-osd id={num}
Finally, you must unset the cluster from ``noout``. ::
