I used debugfs and it shows files hidden under mount points.  To get 
raid working I originally did a very minimal setup, all on /, to get 
raid working.  I forgot to delete the original /usr!

I can't umount /usr remotely anyway.  I guess as long as these files are 
being written to they are not doing any harm and can just sit there 
until I next take the machine down.
