Proxmox 6.2 cluster HA Vms don't migrate if node fails

[pnc1001]

Hello,


I have installed and configured a three node cluster with Ceph file system.

All seems working fine, We can migrate VM from one node to another nodes.

Now, I have done another test, we've roughly unplugged but power cables from server's cpu. The vms are not migrating to the another node.

When I plug ac power cords again, after a few seconds the vms starts on the another or same node. I have also configured watchdog from software level. When I stop the service, VM migrated to another node but restarted.

Can you please help me how to migrate VM without rebooted if node down in cluster?

Regards,
Paresh Chauhan

This thread is probably meant for the PVE forum (I moved it from the one for the mail gateway)

if a node is fenced all guests running there need to be freshly started on a new node (the node does not have the guests ram)

read the reference documentation of HA:
https://pve.proxmox.com/pve-docs/chapter-ha-manager.html

I hope this helps!
