Hello NFS hackers,

I'm running into a problem with NFS stale file handles... I seem to get
them even after just stopping and restarting NFS services on our file
server.

The server is running RedHat 7.2 and kernel 2.4.7-10 (no SMP support).
Clients include some RedHat 7.1 through 7.3 machines, and Solaris 2.6
through 8 machines.

My first suspect is the fairly ancient kernel.  Are there known issues
with kernels from that era?  I'd like to upgrade kernels but am kind of
stuck -- this is a Dell server, we like being able to monitor the
hardware, and last I heard they didn't support OpenManage on newer
kernels.

If there aren't problems with these kernels and there is a possible
work-around ... am I doing something wrong?  My /etc/exports contains only

	/export *(rw,sync,wdelay,no_subtree_check)

I'm not exporting anything else (especially subdirectories), but clients
may mount subdirectories (for example /export/home as /home).  I set
no_subtree_check in the hopes that it would eliminate any state from the
file handles.

Thanks in advance for any info,

	-Joel
