<p class="MsoNormal">I have a three-node hyper-converged oVirt
datacenter running; now I need to add my first storage domain.
I had prepped for this before installing oVirt by creating two
distributed Gluster volumes with 3x replicas (one for the
hosted engine, one for VM storage) –<o:p></o:p></p>

Do you have 2 bricks on each node for the engine volume?<br>

<p class="MsoNormal">Now I’d like to use the “vmdata” volume for
my storage domain. When in webadmin I select “New Domain” I
get a dialog that lets me select GlusterFS as the storage
type, but then requires a “Use host:” setting, and a path. Is
it possible for me to select one of my oVirt hosts (they all
have the ‘vmdata’ volume), and then use “localhost:/vmdata”
for the path? Or will this not work?</p>

Use host -> use any of the hosts.<br>
<meta charset="utf-8">
path -> <host1>:/data<br>
Enter mount options ->
backup-volfile-servers=<host2>:<host3><br>
<br>
<br>
In 3.6, I think the mount options are automatically appended with
backup-volfile-servers. But providing this info here will also work.
The bakup-volfile-servers help in accessing the gluster volume when
the host1 that was used to mount the volume goes down, and any of
the other hosts needs to remount the gluster volume<br>

<p class="MsoNormal">I know this isn’t officially supported yet,
but if I can get it to work somehow, that’d be great :) It’s
a non-production (PoC) setup, so the cost of failure should be
low... That said, I don’t want to trash my rig and have to
redo the whole thing all over ;)<o:p></o:p></p>
