Hi,

I have a btrfs partition on a usb external hard drive which doesn't
mount anymore. I tried doing a btrfs check on it, but it fails with the
error on the subject. The btrfs progs were compiled from git today. I
have a backup of this partition elsewhere, so I can restore from there
if all else fails.

The output of

sudo btrfs check --repair /dev/sdc1 > ~/log/btfs-repair-1.log 2>&1

was

parent transid verify failed on 7624175616 wanted 1431 found 1428
parent transid verify failed on 7624175616 wanted 1431 found 1428
