How can I find out who is on a filesystem when I can't umount it?

  First of all, about finding out what processes are using a filesystem -- the
best utility I've seen for doing that is "ofiles".  You can find out where to
get the source to "ofiles" by telnet'ing to quiche.cs.mcgill.ca (132.206.2.3
or 132.206.51.1) and logging in as "archie".  Type "help" once you get a
prompt to find out how to use archie.  If you don't want to do that, you can
just get the version of ofiles (you probably want "ofiles.new") available in
the comp.sources.unix archives.

  Second, no, you can't force the unmount of a filesystem while it's busy, at
least not on the systems with which I'm familiar (mostly 4.3BSD).  There is
great potential for lossage if you allow that.
