Hi,
On my server I have 2 disk. One where I have proxmox system(and some free space) and second with LXC container. While I was adding another partition to my system disk LXC crushed. After some digging I came to conclusion(don't know if good one) that my system rebooted and mounted partition wasn't set up in /etc/fstab file to mount automatically after system start. So I fixed that and mounted new partition. I've changed also "rootfs" in .conf file and checked file permissions and after that I still got error that system cant find my image:

Thx for any help.
 
Shoudn't rootfs point to a storage instead of a path? So something like "rootfs: YourStorageID:vm-100-disk-0.raw"?

I've changed to rootfs: archive:100/vm-100-disk-0.raw,size=3500G, but there was another error:
unable to parse directory volume name 'vm-100-disk-0.raw'

Thx to chatGPT I figured it out. I've changed Path/Target in /etc/pve/storage.cfg and it's working now.

Thx for Your time.
