[ovirt-users] Two node configuration.

[Johan Bernhardsson]

No it is not safe to only use two nodes as you can end up with split brain.

 So two nodes and an arbiter node is needed. The arbiter doesn't need to be 
that fancy.

Also the installer if installed with gluster as hosted storage (storage for 
the engine) will complain if replica is less than 3.
