I assume you want to un-exportfs some filesystem but still have NFS service for other filesystems in the same machine.
Otherwise you can use nfs script in init.d directory to stop nfs service in stead of un-exportfs.

However, I notice that "exportfs -u" will always cause the client to encounter a "Stale NFS file handle" problem, but without "exportfs -u", I can not umount the filesystem!
