[PVE-User] qmrestore problem with 1.9

Hi All,

I have a shared storage on drbd/LVM with a VM on it. Originally it used 400GB space.

After a kernel problem I made a vzdump --suspend backup about the disk image, which seemed fine, succesfully created, its size around 380GB.

When I try to restore this image to make a backup/recovery, I am not able to restore, I got the following message.

Anyway, vgdisplay shows there are enough space and 400GB space already allocated for the image.

Do you have idea, how to restore the image and how to recover? There are some things on the image I need.

Any help are appreciate!

Thanks, István
