It works also with just two hosts but it's not that safe: a replica-2 GlusterFS
volume affected by a split-brain issue could be not self-healing while with replica-3 you
could rely on quorum enforcement just cause you are using an odd host number.
For oVirt 3.6 we are working on

I do not like the risk part! In that case will have to wait for a
third machine then.
So in future there will be something useful for me but i did not get
it - what exactly will be different between ovirt 3.5 with quoum
enforcment and ovirt 3.6 with Hyper Converged Gluster Support?
