Cluster reboot after adding new node

[PaNggNaP]

Hi Folks,

Today I have added 5 new nodes to the existing cluster and found out the disk raid configuration on one of my servers have a problem and then I reconfigure the raid on that server.
After 1 hour after adding a new node, my whole cluster got rebooted and all the VMs inside rebooted as well.

Proxmox version: 6.4-15


Can you guys have any idea why the whole cluster got rebooted after adding new node?

Is it the common issue for Proxmox?

Hi @PaNggNaP without any logs is hard to help. Usually when nodes reboot its because you have problems with corosync, because of having high latency on the link -> which can lead to whole cluster reboots. Please send:

root@PMX8:~# journalctl -u corosync.service because you are using pve6 (please update, its EOL!) you might need to check it with a different command or by looking at cat /var/log/syslog | grep corosync

Please also post:

• /etc/pve/corosync.conf
• /etc/network/interfaces

Hi @jsterr thank you for your suggestion.

The log output files are attached.

Could you please check and advise what could be the possible cause triggering cluster reboot?

Appreciate your help!!
