Hi all,<br
<br I'm about to
lose one very important vm. I shut down
this vm for maintenance and then I moved the four
disks to a new created lun. This vm has 2 snapshots.<br=
<br
After successful move, the vm refuses to start with
this message:<br

There is a lot of disks when doing a "lvs | grep

The disks which you want to copy should contain the entire volume chain=

Based on the log you mentioned, It looks like this image is

What if you try to deactivate this image and try to run the VM, will=20
it run?
I already tried to do what you suggest, but it is the same, and more=20
this disk is part of a volume groupe, so I can't boot the vm without it.
Is there some unknown command to recover this vm into ovirt?
Thank you in advance.
