If volumeMounts are not added, there will be errors related to PVC. I just want to add a PVC mounted to /var/lib/clickhouse-keeper

 failed to get pvc by name acos/both-paths: persistentvolumeclaim "both-paths" not found
failed to get pvc by name acos/log-storage-path: persistentvolumeclaim "log-storage-path" not found

I have found the same operator error after POD annotations are dropped (by the operator itself):

• POD annotations are dropped with the reconcile of CHK STS  #1469
