Verify the Ceph core services¶

Warning

This procedure is valid for MOSK clusters that use the unsupported KaaSCephCluster custom resource (CR) instead of the MiraCeph CR that is available since MOSK 25.2 as a new Ceph configuration entrypoint.

For the equivalent procedure with the MiraCeph CR, refer to the following section:

Verify the Ceph core services

To confirm that all Ceph components including mon, mgr, osd, and rgw have joined your cluster properly, analyze the logs for each pod and verify the Ceph status:

kubectl -n rook-ceph exec -it $(kubectl -n rook-ceph get pod -l "app=rook-ceph-tools" -o jsonpath='{.items[0].metadata.name}') bash
ceph -s

Example of a positive system response:
