Wait until completing reboot as a Kubernetes level (not Ceph cluster level). 3. If there are other nodes to be rebooted, go to step 1. I should have explained this logic to you as well. I realized that above logic is wrong and I should wait coming back to HEALTH_OK. Unfortunately I doesn't understand the meaning of pg state well and there seem to be several states which mean "pg might be lost". https://docs.ceph.com/en/latest/rados/operations/pg-states/ Could you tell me that pg can become `recovery_unfoud` state in this case?
