Okay, here I'll pick nits. I hope you're not sick of me yet.

1) I would LOVE to unmount the FS, but how? umount /dev/xxx ... device
no longer there. umount /media/xxx ... mount point no longer there.

2) I can't rectify the problems exactly because the FS is mounted
(according to xfs_repair [ustat]), yet not mounted (according to
/proc/mounts). .... unless rectifying the problem means reporting this
as a bug. :-)

3) "Shutting down filesystem" ... isn't this when the new device
should no longer be detected as mounted?

4) come to think of it, if XFS is shutting down, why isn't it
unmounting itself?

Anyway, sorry if I'm being annoying, but I'm really really convinced
this is wrong. :-)

Martin
