How do you handle Proxmox clusters when you only have 1 or 2 servers?

I technically have 3 servers but I keep one offline because I don’t need it 24/7 most point wasting power on a server I don’t need.

I believe I read somewhere that you can force Proxmox it to a lower number but it isn’t recommended. Has anyone done this and if so have you run into any issues with this?

My main issue is I want my VM to start no matter what. For example I had a power outage. When the servers came back online instead of starting they waited for the quorum number to reach 3. (it will never reach 3 because the third server wasn’t turn on.) so they just waited forever until I got home and ran

    I would argue that the node shouldn’t be in the cluster if its availability doesn’t match the others. If you remove the part-time node, your pvecm concerns go away.

    Now, if you have a failure such that the other 2 nodes get restarted, you can manage the VM startups with delays. If one node completes booting 5 minutes before the other, then have the VMs wait 5 minutes or longer before auto-starting. That way, you’ll have your quorum when the VM starts.
