[Question] Proxmox Cluster and Quorum (lemmy.ml)

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 haven't tested this at all, it's just popped into my head, but, could you create a VM on one of the nodes and join that to the cluster?

If it does work, I wouldn't recommend it. But I'd be curious to see if that would work.

That leads to a chicken and egg situation. The Proxmox cluster can't turn on VM because the VM isn't on to be the third node in the cluster number :)
