   I had difficulty accessing an NFS-mounted disk as superuser from 
   a host.
   Mandell suggested:
   
        The problem is that you have to export the file system with root 
        privileges.
        In /etc/exports on B, it should have a line like:
        /u02 -root=0 -access=A
   Thank you.
