- Recovering from ceph-mon failure
-==================================
-
-Any single ceph-mon failure should not take down the entire monitor
-cluster as long as a majority of the nodes are available. If that
-is the case--the remaining nodes are able to form a quorum--the ``ceph
-health`` command will report any problems::
-
- $ ceph health
- HEALTH_WARN 1 mons down, quorum 0,2
-
-and::
-
- $ ceph health detail
- HEALTH_WARN 1 mons down, quorum 0,2
- mon.b (rank 1) addr 192.168.106.220:6790/0 is down (out of quorum)
-
-Generally speaking, simply restarting the affected node will repair things.
-
-If there are not enough monitors to form a quorum, the ``ceph``
-command will block trying to reach the cluster. In this situation,
-you need to get enough ``ceph-mon`` daemons running to form a quorum
-before doing anything else with the cluster.
-
-
-Replacing a monitor
-===================
-
-If, for some reason, a monitor data store becomes corrupt, the monitor
-can be recreated and allowed to rejoin the cluster, much like a normal
-monitor cluster expansion. See :ref:`adding-mon`.
