Hi,
I don't know what happened, but I just logged into my system and
deleted some unused files in my home directory. Just some directories.
Suddenly everything on my system became read only. While rebooting I
think I saw messages like:
"BTRFS Error"
I booted into a live environment to restore my snapshots, then while
mounting the BTRFS root partition I got:
mount: /mnt: wrong fs type, bad option, bad superblock on
/dev/mapper/dm_crypt, missing codepage or helper program, or other
error.
Try to mount normally, then:
dmesg
btrfs check --readonly
Post the results.
You can then try:
mount -o ro,usebackuproot
