Hello,
I have the following bug
https://bugzilla.kernel.org/show_bug.cgi?id=178781 in btrfs check, is
there a way to recover my filesystem in clean state without formatting
or using btrsfck ? Of course, the point is no longer need the files
which are damaged.
So is there a way to recover a btrfs filesystem by deleting the
corrupted data instead of trying to restore it ?
