Option 2 I have the same setup and requirements as you so here is what I am doing - assign the "master" node 2 votes and expect a total of 3. In this case you always have quorum. You can do this by: - follow the guidelines in ProxMox wiki how to edit the corosync configuration (stop the services, etc.) - edit the configuration - bump the configuration version - restart the services Of course this is not supported and you should be careful with the VM ids on both nodes but for homelab it works perfectly.
