I have three nodes in Proxmox VE 5.4. I would like to receive an email notification when one of the Ceph OSDs fails. Is there any way to set up this notification?
There would be the `ceph mgr module enable alerts` [0], not sure if it has been available in Ceph Luminous though. And UPGRADE, UPGRADE, UPGRADE!. If you have old openvz container (guessing), then migrate the whole PVE 5.4 into a VM.
