Looking for Cheap and Easy Quorum

[mhammett]

Recommendations for a low-power and cheap device to put into my Proxmox cluster so that I can have a quorum? I quickly bought stuff last week to move my environment to new hardware. I have three R730s (actually, they sent me R730xds, so I think I got a good deal out of it); two will run PVE, while one runs PBS. The entire environment would fit just fine on one server, but I have a second for some splitting of critical services and restoring should there be a major failure.

However, I have two servers, which does not make a quorum. I'm looking for recommendations on what to get or do to resolve this. It'd be nice if PBS would install inside of PVE or if PBS could be that quorum, but I think that's a bit more work than I'm willing to do.

Im running a 3-node Cluster, 2 nodes as VM-Server and 1 node as PVE+PBS. Works great, just useless at the end.
In the beginning the idea was to run on the PVE/PBS node, a Triliead-VM that does ESXI-Backups.
But since we got completely rid of ESXI, the Trilead-VM doesnt run anymore either and the PVE/PBS node would be better suited as PBS only node.

Just to Convert the node to PBS only is hard afterwards xD
However i see no reason not to run the PBS node as Quorum.

Another Cluster is a 2-node Genoa Cluster, with a quorum device as VM on another Cluster.

But a quorum device is not something that if super important and needs 99,9999% uptime.
So a raspberry does it. Just setup uptime-kuma or something to monitor the raspberry.

Raspberries are pure crap, but a Quorum-Device is really nothing special, doesnt need any ressources or anything special. And you can remove the Quorum Device afterwards or replace it with something better with time. Just monitor it somehow, with pings or whatever.
