Hi Konstantinos.

After having a look at the logs, it seems that the problem you have doesn't 
relate directly to oVirt's support to a single Gluster replica, but for some 
bug in that area. can you please  attach the hole log files so we can open a 
bug for this issue?

Thanks.

Subject: Re: [ovirt-users] Internal Engine Error while adding a new (distribute 
glusterfs) Storage Domain

The good news: there is an an option for this.
The bad news: Only replica 3 is supported. Other options are for 
development purposes.




[root@hv00 ~]# cat /etc/vdsm/vdsm.conf
...

[gluster]
# Only replica 3 is supported, this configuration is for development.
# Value is comma separated. For example, to allow replica 1 and
# replica 3, use 1,3.
allowed_replica_counts = 1,3
