Hi

I just transfered my .raw disk of my container to my new server on a ZFSpool and I cannot start the container, here is the output:

Any help appreciated :)

edit:

when I run a pct fsck 108

Code: 
fsck from util-linux 2.33.1
Possibly non-existent device?
fsck.ext2: No such file or directory while trying to open /dev/zvol/ZFSpool/vm-108-disk-0.raw
command 'fsck -a -l /dev/zvol/ZFSpool/vm-108-disk-0.raw' failed: exit code 8

He is trying to check in `/dev/zvol/ZFSpool/` but there is no folder here, the ZFSpool folder is mounted on `/ZFSpool` and not `/dev/zvol/ZFSpool/ `


Edit 2:

I created the folder zvol in /dev and then created a symblink :

Code: 
ln -s /ZFSpool/ /dev/zvol/ZFSpool

tried to launch the container again and got new error log :

Stop

Sound like there is a problem with the device link


Any idea how to regenerate it ?
