I had two xfs filesystems and I first noticed that /data/Scratch was 
befallen from this bug. I did not care much about this (hence the
name :)) and I wanted to postpone the xfs_db surgery.

Unfortunately I forgot that "/" was also an XFS and it crashed 
yesterday. remounting ro helped a bit (so no process attempted to write 
on it. however, cp'ing from the ro-mounted xfs sometimes hung, 
unkillable), I setup a mini-root somewhere else and followed the
instructions in the FAQ. It did not go too well, lots of 
stuff was moved to lost+found, but every subsequent xfs_repair run 
found more and more errors. I decided to mkfs the partition and make use 
of my backups. my other "scratch" partition is still XFS but mounted ro 
and I'll try the xfsprogs fixes Nathan published on this one.

Oh, and I dd'ed the corrupt xfs-filesystem to a file, so I can play 
around with this one as well.

If anyone is interested, here are the typescripts from the horrible 
xfs_repair runs: http://nerdbynature.de/bits/2.6.18-rc2/log/

cheers,
Christian.
