Lowering the quorum permanently on a cluster?

[lyricnz]

Hi. I have a proxmox cluster of two nodes, but one of them is my "dev" server and spends most of it's time powered off. How can I make the "prod" server come up properly (say after a power failure)? Right now I have to login to it via ssh and run "pvecm expected 1" which is a bit of a pain when the machine hosts my router and DHCP server, so access is a pain.

This seems to be the same as https://forum.proxmox.com/threads/cluster-and-quorum.7786/#post-59335

The commands in that post are out-of-date, so are probably now:

systemctl stop pve-cluster

/usr/bin/pmxcfs -l

nano /etc/pve/corosync.conf

Will try it once everyone is off the internet (one of the proxmox nodes hosts my opnsense and pi-hole).

You could run something like a Raspbery Pi as a qdevice acting as a third voter.

Applied the change (to make the "prod" node get 2 votes), and now it boots and starts up fine, with or without the "dev" node.

You can assign more votes to the primary node in the /etc/pve/corosync.conf file and updating the line:

quorum_votes: 1

to

quorum_votes: 2

and then incrementing the number in line:

config_version: 7

to show that theres been a change to the config
