all nodes rebooted suddenly

[lcummings]

Anyone have any idea what would cause every node in my 17 node cluster to reboot? Were on version 4.2.2 After reading the logs i cant tell what started it the first log recorded for that day and time is VM114- Start. I want to figure this so i can prevent it from happening again .

Do you have HA enabled guests on each node? Could be network problems causing the nodes to not see a quorum part of the cluster anymore. If they have HA resources running they will fence (reset) themselves.

Were on version 4.2.2

Please do upgrade! Version 4 is EOL for quite a while now.

so i just found out from a coworker he found server 115 was trying to migrate and was failing because it was locked for backup. So he ran a qm unlock and that started a chain reaction an all the nodes started rebooting.
