VM crashed and its disk partitions seem to be unallocated.

[powersupport]

Recently we performed an upgrade on our proxmox cluster and we faced an outage. we have 4 node clusters, after completed the upgrade in 3 rd node, we tried to reboot node 3, but what happened is the whole cluster, which means all nodes went rebooted. We suffered a lot due to the downtime, it lasted around 15 minutes after that nodes went up.

Upon checking we were able to see that a VM is crashed and its disk partitions seem to be unallocated. May I know the root cause of the issue?

Thank you,
