Hi, Sorry for my bad English:( Ovirt could not import my VM and disks from original storge-domain. It is an NFS share on a server. Then I create an another NFS share on same storage and attached to ovirt as new storgae domain. At this step I've created a new VM on new storage-domain with same disks. (three think provisioned, 100GB, 60GB and 13TB disks). It was necessary, because ovirt cant import my original disks and VM from the re-attached storage domain. Finally I renamed my old disks from old storage domain to new on new storgae domain (it was possible because are there on same file system on nfs server) At this moment only two virtual disk working fine. The 100 and 60GB disks does working fine, but the 13TB is not. It has a snapshot. Or not? Is it a snapshot or not?
My problem is inside VM I see the content as raw disk. I thing Ovirt don't want to use it as a snapshotted image. Or what ? Thank you.
