Thanks Strahil

I made a new gluster volume using only gluster CLI. Mounted the old volume and the new volume. Copied my data from the old volume to the new domain. Set the volume options like the old domain via the CLI. Tried to make a new storage domain using the paths to the new servers. However, oVirt complained that there was already a domain there and that I needed to clean it first. . 

What to do ?

Thank You For Your Help !
