Hey Sahina,
Thanks very much.
I've taken a quick glance and it does mention I need a third host which
I don't have.
However, since I wrote, I removed everything. Had to force remove
hosts
however the gluster setup and data in it stayed (Or so I'm thinking).
I'll read the article more thoroughly however is there a specific
procedure for adding existing oVirt gluster volumes back into a cluster?
One additional question. Is the sequence below correct?
1) Create Data Center
2) Create Cluster within the DC
When you create the cluster - there's an Import cluster option, if I
remember correctly. This should discover the peers and volumes and add
it to the engine
Trying that now. On a side note, the autodiscovery box is hard to edit.
So in the meantime, trying to up the version to take advantage of some
new features and ensure Gluster 6 is fully supported. Not having luck
with the oVirt UI upgrade at the moment ( Not a self hosted engine.
It's on a separate VM. ):

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

3) Create a Domain within the Cluster
4) Add hosts to DC
5) Import Gluster Volume
4 & 5 not required if you change step 2 to import.
You are running into errors below because the engine sees the addition
of new hosts as gluster peer probing to a new cluster
Some issues. I create a DC, add a Cluster then add the Host to it.
Then
I try to add another the second node but it says It's already in a
cluster. There is no other cluster and the second host is not listed
anywhere.
So I try to remove the first host to restart from the beginning. It
says I can't remove the only host now till it's in maintenance.
Maintenance is grayed out. I wait a bit guessing there's background
processes running and can finally remove to readd.
When I try to redo the operation and get to the step of adding another
host, I get:
"Error while executing action: Server mdskvm-p02.nix.mds.xyz
<http://mdskvm-p02.nix.mds.xyz> is already
part of another cluster."
But I can clearly see it's not there via another oVirt UI window.
oVirt:
ovirt-engine-4.2.1.7-1.el7.centos.noarch
Hosts:
root@mdskvm-p01: ovirt-host-4.2.3-1.el7.x86_64
root@mdskvm-p02: ovirt-host-4.2.3-1.el7.x86_64
System prevents me from removing and restarting the process again
