Dear all, Anyone using CloudStack with Ceph RBD as primary storage? I am using CloudStack 4.2.0 with KVM hypervisors and Ceph latest stable version of dumpling.
Based on what I see, when Ceph cluster is in degraded state (not active+clean), for example due to one node is down and in recovering process, it might affect CloudStack operations. For example: - Stopped VM cannot be started, because it says cannot find suitable storage pool. - Disconnected host cannot be reconnected easily, even after restarting agent and libvirt on agent side, and restarting management server on the server side. Need to keep on trying and suddenly it will be connected/up by itself. Once Ceph has recovered and back to active+clean state, then CloudStack operations will be back to normal. Host agents will be up, and VMs can be started. Anyone seeing similar behaviour? Looking forward to your reply, thank you. Cheers.
