Hi guys,
I am running btrfs v0.19 and have a problem after filling my drives,
attempting to delete the directory which had caused the drives to
become full, after which the machine locked and was reset. After which
basically, it wouldn't mount the drives.
An offline fsck revealed the "aborted" message after lots of "parent
transid verify failed on 2721514774528 wanted 39651 found 39649" type
messages.
My setup was 2x 1tb drives with mirroring (using btrfs). I don't
recall the command line options I used.
I installed the latest unstable tools from Chris Mason, and attempted
to use a newer SB, which all had the same result.
Also, I attempted to use btrfs_rescue.c, but this resulted in:
btrfs_rescue volumes /dev/sdb
ERROR: Cannot read block at 0x124c9c02000!
Also, I've now removed the second drive & re-used it.
btrfs-show
failed to read /dev/sr0

Btrfs v0.19-35-g1b444cd
I also get;
btrfs-debug-tree /dev/sdb
failed to read /dev/sr0
btrfs-debug-tree: volumes.c:1367: btrfs_read_sys_array: Assertion
`!(ret)' failed.
Aborted
Hopefully, there is something that could be saved, but it's not
critical for me (it was mainly backups of which I keep plenty else
where). It would be handy if it was recoverable.
I am able to make a dd copy of the whole drive and try any new fsck
type software that is around?
