First off, when you ask for help, don't do:

> Followup-To: poster

It gets people mad when inews refuses to place the article into
the newsgroup "poster".  They may not take the time to go back
and fix it.  

If you would prefer an email response, specify so at the end of your
posting and most people will adhere to it (unless they think it is
a subject that many people would be interested in).

1. What does ps -ef say (i.e. what processes are running)?
2. Do you have any other file systems mounted on top of /usr?
3. Are you sure that you are not in /usr

I don't think fuser is *guaranteed* to find every process on the file 
system (it does do a pretty good job though).  I seem to recall some
situations where fuser didn't find processes on the file system.
