If I’m not wrong GlusterFS in oVirt requires 3 hosts.
Here’s the RHHI guide, it’s pretty much the same for oVirt:

Hi all
After screwing my infra with the update to 4.2 (probably a bad manipulation), i am
planning a rebuild of the entire infra. First i want to replace my NFS storage with a
glusterfs storage. All documentation tell me that i need 3 hosts.. but for the moment i
only have 2 but planning to had more later.
So does it make sense to start with 2 hosts and use glusterfs as the storage domain(lets
says with a replicate of two with all its limitations).
If it make sense,
1- what is the best way to do it.
2- how hard will it be to had the 3rd host when available and make it replica
2+arbiter.
Also in a setup where i have 3 hosts (replica 2+arbiter) does all the 3 hosts can run
users vm?
Thanks for your inputs.
Carl
