<p>Hi All,</p>
<p>I have a shared storage on drbd/LVM with a VM on it. Originally it used 400GB space.</p>
<p>After a kernel problem I made a vzdump --suspend backup about the disk image, which seemed fine, succesfully created, its size around 380GB.</p>
<p>When I try to restore this image to make a backup/recovery, I am not able to restore, I got the following message.</p>
<p>Anyway, vgdisplay shows there are enough space and 400GB space already allocated for the image.</p>
<p>Do you have idea, how to restore the image and how to recover? There are some things on the image I need.</p>
<p>Any help are appreciate!</p>
<p>Thanks, István</p>
