Best solution for following problem...

[warped]

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

The third synopsis shows how to unexported a currently exported directory. When using exportfs -ua, all entries listed in xtab are removed from the kernel export tables, and the file is cleared. This effectively shuts down all NFS activity.

(from exportfs( - Linux man page)

What about exportfs -r ?

Well,

Can explain why I overlook -r option.
It looks like thing which I'm looking for.
After some basic test all seems to be OK.
thx for Your replay.
So nice somebody trying to help.
All the best
