proxmox reboot whole cluster

[itvietnam]

Hi,

I have 10 node named from node1 to node10.

1. I have shutdown node9 for maintenance.
2. Then i removed node2 by pvecm delnode node2
3. Later i turn on node9 back and whole system shutdown (reboot random). It seems something fence all nodes.

May i know how to turn on node9 back to the system without fencing happen?

My guest: this problem caused by step 2 by deleting node2 out of system. Hence corosync update and node9 does not update this new config.

Fencing takes place only in case of lost Quorum - check the syslogs about the period when the restarts took place from all nodes to figure out what exactly has happened.
