Comment on Virtualizing my router - any experience to share? Pos/cons?
GameGod@lemmy.ca 1 day agoIf you just use 2 nodes, you will need a q-device to make quorum if you have one of the nodes down
I could just use VRRP / keepalived instead, no?
I should try Proxmox, thanks for the suggestion. I set up ZFS recently on my NAS and I regret not learning it earlier. I can see how the snapshotting would make managing VMs easier!

Proxmox uses a voting system to keep cluster integrity.
Check it out, it’s free and does a lot of things out of the box that take a lot of manual work otherwise. And the backup server is stellar. It does take a while to wrap your head around the whole way it does things, but it’s really powerful if you spend the time to deep dive it.

So 3+ hosts for clustering or 2 hosts and an qdevice to fake it

Yes. You can just get by with 2 devices but you need to set expected_votes=1 in the cluster config somewhere, don’t recall where, and I’ve encountered issues with stability with that solution, seems like it’ll get undone though I haven’t used it for years to say if that’s still the case.
The q-device will work on anything Linux that’s available when the second node is down. Not having the tie-breaker isn’t the end of the world, it just means you have to go in after you bring up the second node and start some things manually, and if you’re replacing nodes in a 2-node cluster, it’s much nicer to have the q-device.

Yeah, it’s /etc/pve/corosync.conf you can set quorum votes to 2 for a device. But it’s easy to get the file overwritten. Link
Or you can use pvecm expected 1 on both hosts or pvecm --votes 2 on one device.

Without a 3rd they can get confused if they loose contact but both nodes are up. Like both are in charge as one vote is enough
