I'm looking at this, but I have no brighter idea than just running du
on it, which is taking a very long time.  So if any other roots have a
better idea to figure out what's going on and/or fix it, feel free to
kill my du process (running as root) and delete /tmp/userstore-du on
hemlock.  (I'm also not quite sure what I'd do if I did figure out the
culprit, since I don't want to delete users' data without their
permission unless it's clearly useless.)

It looks like a huge volume, so it makes sense that it would take some time to complete.

Are quotas enabled on the volume? That might give you a quick snapshot of who the biggest user is.

You could try running the du in a subdirectory, which might give you some more ideas about big directories. (You can try: du -k | sort -rn).

I'm not a root, so I can't help in the problem analysis except by writing here. :)
