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]}') bash
ceph -s
