Verify the Ceph core services¶

Warning

This procedure is valid for MOSK clusters that use the MiraCeph custom resource (CR), which is available since MOSK 25.2 to replace the unsupported KaaSCephCluster resource. And MiraCeph will be automatically migrated to CephDeployment in MOSK 26.1. For details, see Deprecation Notes: KaaSCephCluster API on management clusters.

For the equivalent procedure with the unsupported KaaSCephCluster 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 deploy/rook-ceph-tools -- bash
ceph -s
