Hi,=20
Sorry for my bad English:(=20
Ovirt could not import my VM and disks from original storge-domain. It is a=
n NFS share on a server.=20
Then I create an another NFS share on same storage and attached to ovirt as=
new storgae domain.=20
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, bec=
ause ovirt cant import my original disks and VM from the re-attached storag=
e domain.=20
Finally I renamed my old disks from old storage domain to new on new storga=
e domain (it was possible because are there on same file system on nfs serv=
er)=20
At this moment only two virtual disk working fine. The 100 and 60GB disks d=
oes working fine, but the 13TB is not. It has a snapshot. Or not? Is it a s=
napshot or not?=20
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 ?=20
Thank you.=20

Hi Tibor,
Can you please explain this part: " After this I just wondered, I will ma=
ke
a
new VM with same disk and I will copy the images (really just rename)
fro=

original to recreated."
What were the exact steps you took?
Thanks
