Thanks for the documentation pointer about RHHI.
I was able to successfully setup all three Nodes. I had to edit the final gdeploy File, as the Installer reserves 20GB per arbiter volume and I don't have that much space available for this POC.

The problem now is that I don't see the third node i.e. in the Storage / Volumes / Bricks view, and I get warning messages every few seconds into the /var/log/ovirt-engine/engine.log like:

2018-02-13 15:40:26,188+01 WARN  [org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesListReturn] (DefaultQuartzScheduler3) [5a8c68e2] Could not add brick 'ovirtpoc03-storage:/gluster_bricks/engine/engine' to volume '2e7a0ac3-3a74-40ba-81ff-d45b2b35aace' - server uuid '0a100f2f-a9ee-4711-b997-b674ee61f539' not found in cluster 'cab4ba5c-10ba-11e8-aed5-00163e6a7af9'
2018-02-13 15:40:26,193+01 WARN  [org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesListReturn] (DefaultQuartzScheduler3) [5a8c68e2] Could not add brick 'ovirtpoc03-storage:/gluster_bricks/vmstore/vmstore' to volume '5a356223-8774-4944-9a95-3962a3c657e4' - server uuid '0a100f2f-a9ee-4711-b997-b674ee61f539' not found in cluster 'cab4ba5c-10ba-11e8-aed5-00163e6a7af9'

Of course I cannot add the third node as normal oVirt Host as it is slow, has only minimal amount of RAM and the CPU (AMD) is different than that one of the two "real" Hypervisors (Intel).

Is there a way to add the third Node only for gluster management, not as Hypervisor? Or is there any other method to at least quieten the log?
