4 nodes

[mer0x39]

Hello, please suggest me which will be the best method to add 4th node in my proxmox homelab cluster ? It will be online only few days/week, It doesnt matter for me to be HA or any else, I only want to see in the same GUI, the rest of 3 servers are 24/7, but for any reason if one of them goes down and also the 4th node is down, I want the VMs to still work, it s possible without qdevice? If yes, how should corosync.conf look like? Thank you

You can mess with the expected votes parameter.

You could give the three 24*7-Nodes quorum_votes: 2 and leave the fourth one at the default value of "1".

Now you have 7 votes when all machines are up. If your fourth one is turned off and another one fails you are down to 7-1-2=4 which is above 50%.

Make sense, thank you!
