PVE upgrade 6 to 7 issue

Jan 18, 2020

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 and fine, anyone knows such a scenario? what could be the reason for this issue?

What we did is,

1) upgraded Ceph nautilus to pacific
2Upgraded pve 6 to 7

could you post the journal of the third node and one of the other nodes that got rebooted, starting before and ending after the reboots (a few minutes in both directions should be enough).
