Proxmox LXC error

[MaC@ToC]

Hi, I'm sorry,

Since yesterday I've had this error on a docker lxc that I don't understand:

root@proxmox:~# pct start 103 --debug

I think I understand that he can't put something together but I don't know how to look.

Could you help me?

Looks like a ext4 superblock error. You can search for mount an ext4 with other than the default superblock manually, then run fsck onto, umount and try to start lxc again regulary. Remaining question is why the ext4 superblock could be corrupted in image which is probably a follow up error of the underlying storage used for the lxc image itself.
