[ovirt-users] help: renamed master volume

Im pretty new to ovirt. Trying to upgrade an old install from 4.1 to 4.3 on the way, I browsed into the Storage area, in one of the nodes. Noticed under the "Volume groups", area that the volumes were named after some loong ID string. Saw there was a "rename" button. figured it would be just like renaming a VM. thigns would just get auto adjusted. but after I renamed to something in english, the cluster is freaking out, "cant find master domain: u'spUUID=xxxxxxx, msdUUID=xxxxxxx' " and under Storage: Storage DOmains, the Data(Master) is down. How can I recover from this ASAP? :-(
