Exactly that one. Sadly, I got no clue how big is your snapshot(s). Maybe even with those extra Gigs, it's still too much to merge it. If you have any other VMs there, try to move their disks away in order to release more space. Otherwise, you will have to find another brick to extend the volume. How many snapshots do you see in oVirt ? Maybe you have more than one snapshot.
