Thanks for your advice. I'll keep in my mind. :)

It sounds bad. Is it possible to save the data or part of them?


> Are you sure that is the very first error message you hit?

My .bash_history doesn't show timestamp so I'm not really sure which
critical/error
message is exactly right after the first `btrfs check --repair`. I
tried to make log file
smaller and excerpted only btrfs messages before the first critical
message in the
attachment. I'm not so familiar with mailing list. Could you see `btrfs_.log`?

Is this patch safe for saving my btrfs? If it is, I can build btrfs-progs.
