Heh.  The filesystem was a 2.0 TB LUN on an EMC CX300 SAN.  RAID, redundant
connections, the whole nine yards.  Looks like we either hit a bug in
the HBA driver or tripped some kind of Linux 2.4.5-esque filesystem
damage.  It won't even fsck.

Somehow, after you stare at man pages long enough, you start to think
you know what's there.  For me, at least, I only *think* I know.

I've often found that asking questions on a mailing list is a great
way to set this straight!  Thanks for the tip Paul.  Funny how it was
staring me in the face this whole time!
