NFS and Mac OS X Server

[Lance Westerhoff]

Hi All-

So this is an annoying problem and I'm not sure how to address it.

I have a Mac OS X Server 10.4 box serving as my home directory server  
to a bunch of clean-install "Red Hat Enterprise Linux Client release  
5 (Tikanga)" clients. Using nfs, all of my users are mounted back to  
the OS X box for the home directories.  Most of the time, all is  
well. But occasionally, I have strange errors.  Here is one that is  
particularly annoying.  While sitting on one of the clients and I try  
to delete a directory....I receive the following error.  When I login  
to the server, I can delete the directory with no problem.  What's  
going on?  Thanks!

[user at rh_client ~]$ rm -rf directory/
rm: cannot remove directory `directory/': Device or resource busy
osx_server:~ user$ rm -rf directory/

SUCCESS!

Currently, the directories are statically mounted on the rh_client  
box using the following fstab:

[user at rh_client ~]$ grep osx_server  /etc/fstab
osx_server:/Users             /Network/Servers/osx_server/Users    
nfs     defaults        0 0

Thank you for any insights you can provide!
