Hello, I'm getting this error when trying to start a container or vm. I don't know what exactly happened, it was all working before.
Code: 
run_buffer: 314 Script exited with status 32

lxc_init: 798 Failed to run lxc.hook.pre-start for container "108"
__lxc_start: 1945 Failed to initialize container "108"
TASK ERROR: startup for container '108' failed

They are also missing in /dev/pve
Code: 
root@server1:~# ls /dev/pve/
data_meta0  data_meta1  root  swap
root@server1:~#

They show up in the local thin-lvm

But the usage of the local thin-lvm is at 0

You could check what lvdisplay and vgdisplay are reporting. Looks like there is a problem with your thin pool.
