node-maintenance does not live migrate VMs

[willifehler]

Hey there,

a have a Cluster with 26 nodes. On each node I have the same problem that:

ha-manager crm-command node-maintenance enable $(hostname -s)

does not migrate the VMs to different Hypervisors in my cluster. On a different Cluster this is working fine.

Is there any setting or logfile that I can check?

Regards - Willi

Hi!

You can query the logs of the HA CRM with journalctl -u pve-ha-crm, which needs to be run on the manager / master node. The same applies for any HA LRM, which can be queried on any node with journalctl -u pve-ha-lrm. Please post the output of the HA CRM when maintenance mode is enabled and the output of the HA LRMs on the nodes, where the services are migrated to.

On another node, how are the votes distributed over the cluster? A even numbered node count in a cluster can lead to split brain.

Also, are these VMs configured as HA and not limited only to this node via HA groups?
