NFS puzzle

[Gerald Combs]

In the exports(5) man page on one of my systems the "nohide" section says

    The  nohide  option  is  currently only effective on single host
    exports.  It does not work reliably with  netgroup,  subnet,  or
    wildcard exports.

You might try changing your exports to match a specific host or exporting
(and mounting) /mnt/iso/mdk91.1 explicitly.
