[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

If you are not using any HA feature and only put servers into the same cluster for ease of management.

You could use the same command but with a value of 1.

The reason quorum exist is to prevent any server to arbitrarily failover VMs when it believes the other node(s) is down and create a split brain situation.

But if that risk does not exist to begin with, so do the quorum.
