Hi Adam,

The arbiter holds only metadata for gluster to be able to resolve any potential 
split brains. It can run on another host (not in the 2 replicas)  and the only 
requirements are:
1. Low network lattency - you don't want to put it in Chona, unless your 
replica servers are also there :)
With remote arbiter - the lattency will affect you only when 1 of the replicas 
is down.
2. Fast storage that can easily create the files' inodes. I would preffer a SSD 
, but even high speed rotational disks are OK

In other words, you should create gluster bricks like this one:
server1:/gluster_bricks/myvolume/brick1
server2:/gluster_bricks/myvolume/brick1
arbiter:/gluster_bricks/myvolume/arbiter_brick

In this case, if a node dies - the other node + arbiter will have quorum and 
will serve any I/O for oVirt.
The arbiter_brick does not require much space, as only metadata will be written.

Actually with hyperconverged setup you have 2 clusters on the same nodes - 
storage (gluster) & oVirt (virtualization).

Best Regards,
