Hi Tibor,
Can you please explain this part: "After this I just wondered, I will make
a new VM with same disk and I will copy the images (really just rename)
from original to recreated."
What were the exact steps you took?
Thanks

Hi,
Thank you for your reply.
So. I have a disk with snapshot. Or - really - I just think that is a
snapshot. It was attached originally to a VM (with other two disks, that is
not have snapshot) I did a detach-attach-storage procedure, but after
attach, - I don't know why - ovirt could not import the VM and disks from
this (ovirt said it is not possible). After this I just wondered, I will
make a new VM with same disk and I will copy the images (really just
rename) from original to recreated.
It was partial success because the VM can boot, but the disk, where there
is a snapshot I can't read the LVM table. I see just it seems to corrupt.
Now this disk in a very interested state: I can see the snapshot datas
from the vm as raw disk.
I think Ovirt don't know that is a snapshotted image and attach to VM as
raw disk.
So my really question, how can I add this disk image as good to ovirt?
Please help me, it is very important me.:(
Thanks in advance,
Have a nice day,
Tibor

Hi Tibor,
I am not sure I completely understand the scenario.
You have a VM with two disks and then you create a snapshot including the
two disks?
Before creating the snapshot, did the VM recognize the two disks?
