Hello,
i don't know if it's the right place to post my problem.
yesterday my btrfs partition (/dev/sda4) worked very well but now i
can't mount my btrfs partition anymore.
it says : wrong fs type, bad option, bad superblock on /dev/sda4,
missing codepage ...
i know btrfs is still in developement, but i would try to recover a
file on this partition.
i tried many options of mount (-t btrfs -o recovery -o degraded...) but
it's always the same issue.
i tried many commands in order to recover my file, but nothing seems to
work :
