Hi, I recovered from this error by import my base-image in a new machine and make a restore of the backups.
But is it possible "by hand" to merge latest snapshot in to a base-image to get a new VM up and running with the old disk image?
Looking at your vdsm logs the snapshot should be intact, then it can be manually restored to the previous state. Please restore the images dirs, removing the "old" and the "orig" dirs you have. You need to change the engine db accordingly too. Later you can retry the merge. Regards.
I have tried with qemu-img but have no go with it.
Regards //Ricky

Hi Ricky,
from going over your logs, it seems like create snapshot failed, its logged clearly in both engine and vdsm logs [1]. did you try to delete this snapshot or was it a different one? if so, not sure its worth debugging.

Hi, The task did not finished but it broked my VM. What I have right now is a VM with a base-image and a snapshot that I need to merge together so I can import the disk in a new VM.
I have attached the logs and even the output from the tree-command.

I was trying to delete a snapshot from one of my VM and everything started fine.
The disk image is a thin provisioned 100GB disk with 8GB data. I just hade one snapshot and it was that one I started to delete. After more than two hours I look in the folder with that VMs disk images and found out that there was i new created file with a size of around 650GB and it was still growing.
