Hi,
I am trying to revover btrfs filesystem after upgrade to ubuntu precise.
I have tried:
$ sudo fsck -r -V -t btrfs /dev/sdb8
fsck from util-linux 2.20.1
[/sbin/fsck.btrfs (1) -- /dev/sdb8] fsck.btrfs -r /dev/sdb8
root 5 inode 251945 errors 400
root 5 inode 251954 errors 400
found 11405721600 bytes used err is 1
total csum bytes: 10576496
total tree bytes: 557309952
total fs tree bytes: 517558272
btree space waste bytes: 149250982
file data blocks allocated: 25370923008
referenced 10748383232
Btrfs Btrfs v0.19
$ sudo btrfsck /dev/sdb8
root 5 inode 251945 errors 400
root 5 inode 251954 errors 400
found 11405721600 bytes used err is 1

Btrfs Btrfs v0.19
but nothing worked at all.
is there any other way how to fix it ?
I do not mind if some data are going to be lost. some guidance if exists I would much appreciate.
thank you,
kind regards,
M.
