Re: corrupted btrfs volume: parent transid verify failed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Halp!  I was recently forced to power cycle my desktop PC, and upon
restart, the btrfs /home volume would no longer mount, citing the
error "BUG: scheduling while atomic: mount /5584/0x000000002".  I
retrieved the latest btrfs-progs git repositories from
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git
and http://git.darksatanic.net/repo/btrfs-progs-unstable.git -b
integration-20110805, but when running "sudo ./btrfsck -s 1
/dev/mapper/home" from either repo builds, I receive the error "parent
transid verify failed on 647363842048 wanted 210333 found 210302"
(repeated 3x).  I've also tried the flags -s 0, -s 1, and -s 2, all
with the same results.

I take care to complete a full dd copy of my disk every 2 weeks, but
my previous backup is nearly 2 weeks old and I've put in almost 2
weeks of effort on my masters thesis since then.  I'm quite desperate
to recover this volume.  Any help is appreciated, as I've exhausted
the existing suggestions from the mailing list posts to date.  I've
tried to ask in #btrfs, but suspect that they're all sleepy bearded
people :(

Regards,
