I use cvsup in CVS mode maintain a local copy of the repository, and
then use cvs to update the local machines from that repository. My copy
of the cvs repository lived on the dead disk. I fired up mozilla on my
laptop to go shopping for a replacement disk ...

There's a hole in the bucket, dear Liza, there's a hole.
I was able to salvage all the data and scrounged up a couple of
replacement disks, and when I loaded the data onto the new disks it
became apparent that there are some severe performace problems in the
filesystem code, probably in the inode and/or block allocators.
Restoring 5 GB of data to the cyrus imap spool directory that was also
on that disk took about 6 hours ...
