[ovirt-users] Disk move succeed but didn't move content

Hi, I've a fresh new install of ovirt 4.3 and tried to import an gluster vmstore. I managed to import via NFS the former data domain. The problem is that when I moved the disks of the vms to the new ISCSI data domain, I got a warning that sparse disk type will be converted to qcow2 disks, and after accepting, the disks were moved with no error. The problem is that the disks now figure as <1Gb size instead of the original size and thus, the vms fail to start. Is there any way to recover those disks? I have no backup of the vms :-( Regards
