Lxc not starting, schnapps unusable, help pls!

since today I have bad situation here - my LXC container not starting, wanting going back in time with schnapps also no go:
root@turris:~# schnapps list
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1,
missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
    # | Type      | Date                      | Description
------+-----------+---------------------------+---------------------------------
ERROR: cannot find real path for '/mnt/.snapshots/@81': No such file or directory
   81 | single    |                           | 
ERROR: cannot find real path for '/mnt/.snapshots/@87': No such file or directory
   87 | single    |   

any ideas?
Thx

Hello,
please can you tell us, which services are you running inside your LXC container?

There can be two issues:

  1. broken filesystem
  2. corrupted eMMC

Please first re-reflash router with medkit if works then great! If it doesn’t (then) you would need to write email to tech.support(at)turris(dot)cz.

thx, btrfs not fixed from rescue shell, mekdit failed also, do you think its time for RMA?
