[NFS] Best solution for following problem...

Hi *

I'm looking for advice for best solution for following problem:

I have file server sharing files to diskless clients via NFS

I want  have setup, where pluging ext. USB HDD will be dynamically 
visible on clients as new <subdir> with HDD contents.
So if user plug USB HD on server, diskless clients should see plugged 
HDD contents in dynamically created <subdirectory> with name equal to HD 
label and HD contents inside it.

I already wrote udev script which auto creates subdir=<label> in NFS 
server shared dir, and automounts USB HD in this subdir.

Issue is that diskless clients don't see this subdir  unless  I issue on 
server

exportfs -ua
exportfs -a

Problem is that  above unexporting/exporting sequence issued on server 
brokes existing NFS shares between clients and server.

What is most elegant solution for such functional requirement ?

thx in advance

<changed mailing list address to correct one for linux-nfs>

Doesn't 'exportfs -r' work for you?
