[ovirt-users] 2 Node oVirt Cluster

Hey there, I tried using oVirt for some time now and like to convert my main Proxmox Cluster (2 Nodes + RPI for Quorum) to oVirt. But I obvioulsy need three servers to do HA. Now I am asking myself: can't I just use the PI as an arbiter node for the Selfhosted-Engine on gluster? I tried running the playbook already, but it's always failing and even if the gluster deployment would go through, it would most likely fail aftwards, right? Before I waste too much energy and time into that, does anyone of you guys use a 2 node cluster? And no I can't add another node (energy + space + money)! Also I know with doing that I'm totally on my own etcetera Thanks!
