Procedure

1. Log in to a Controller node as the heat-admin user:

   $ nova list
   $ ssh heat-admin@192.168.0.25

2. Check the health of the cluster:

   $ sudo podman exec ceph-mon-<HOSTNAME> ceph health

   Copy to Clipboard Toggle word wrap

   If the cluster has no issues, the command reports back HEALTH_OK. This means the cluster is safe to use.

3. Log in to an overcloud node that runs the Ceph monitor service and check the status of all OSDs in the cluster:

   $ sudo podman exec ceph-mon-<HOSTNAME> ceph osd tree

4. Check the status of the Ceph Monitor quorum:

   $ sudo podman exec ceph-mon-<HOSTNAME> ceph quorum_status

   Copy to Clipboard Toggle word wrap

   This shows the monitors participating in the quorum and which one is the leader.

5. Verify that all Ceph OSDs are running:

   $ sudo podman exec ceph-mon-<HOSTNAME> ceph osd stat
