Proxmox Corosync quorum votes change

[blinked]

Hi guys !

I have problem/question: now i have 8 nodes proxmox cluster but i wanna to have only 2 nodes online 6 nodes offline.

So if i change in
/etc/pve/corsync.conf
from
quorum_votes: 1
change to
quorum_votes: 2

on two nodes i will have quorum if only 2 nodes from 8 will be online?

It's this safe and possible to change quorum votes for nodes.

Hi,
the quorum_votes tells how much votes the node has. So if you have 8 nodes, you will need a total of 5 votes in order to have quorum.

I understand manual but is there possibility to change quorum votes for one node, so one node will have more votes than other nodes

Yes, you can edit the corosync config file. Follow the user guide carefully https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_corosync_configuration

THX, i will try to change numer of votes later.

@Chris do you think this is possible to do change number of votes per node to make 8 node cluster working with only two nodes online? Somebody tried this?

im trying to rebuild my homelab and i came upon an interesting question, maybe anyone has an idea:

i have lte's say 3 Nodes, 2 for testing and 1 primary for live VM's ... like mentiont above the move nodes i have the harder it is to chanke votes per node manual to achive certain behaviors. But what is if i set the votes of node 2 and 3 (testing Nodes) to 0 and the main node has 1 or 2 votes: so testing-nodes cant never achiev quorum and only the main node is "MAIN" ?
would this work?

Hi,

Why are you running this in cluster ?
If you want to mess with quorom, just use the 3 servers as standalone node.

Best regards,

Propably not. What do you want to achieve? You don't need a cluster for migration just setup the datacenter manager in a vm and you can migrate between the nodes if needed.
