Description Filip Balák 2022-04-13 14:57:07 UTC

Description of problem:
There is currently deployed only one MGR pod. There should be more MGR deployed across multiple nodes. Having MGR highly available is also recommended by ceph documentation: https://docs.ceph.com/en/latest/mgr/administrator/#high-availability and it would also make sense to keep 2 different MGR alerts that we have now: CephMgrIsAbsent and CephMgrIsMissingReplicas (if we have only one MGR then we don't need both alerts)

Version-Release number of selected component (if applicable):
OCP v4.10.z
ODF v4.10.0
ocs-osd-deployer v2.0.0
