To be more specific: In my try first I do an exportfs -u of the export =
i=20
need to move and then i do an exportfs -f.
Client side the copy wait for a while and then gives some "Permission=20
denied" and exit.
Server side the problem, as already said is this one:

Jun  9 11:54:16 ubuntu-nodo1 lrmd: [692]: info: RA output:=20
(share-a-fs:stop:stderr) umount: /share-a: device is busy.#012=20
(In some cases useful info about processes that use#012         the=20
device is found by lsof(8) or fuser(1))
Jun  9 11:54:16 ubuntu-nodo1 lrmd: [692]: info: RA output:=20
(share-a-fs:stop:stderr)
Jun  9 11:54:16 ubuntu-nodo1 Filesystem[4065]: ERROR: Couldn't unmount=20
/share-a; trying cleanup with KILL
Jun  9 11:54:16 ubuntu-nodo1 Filesystem[4065]: INFO: No processes on=20
/share-a were signalled

As you can see the filesystem resource agent tries to unmount /share-a=20
but even if fuser or lsof does not give output, it still remains locked=
=20
(by nfsd, of course).

Have you got any other suggestion? Thanks a lot for your help.
