    Hi,
    I received various replies, from make sure you are
    using nfsv3 (which i am) to others pointing out a flaw
    on tru64 Unix v4.0(g). The latter goes like this::
    - I've found that they sometimes show negative numbers
    for drive space when a very large filesystem is NFS
    mounted. My guess is that v4 used an integer that
    wasn't large enough to account for that much disk
    space.

    - Looks like you are over a 32 bit limit.
    % bc
    bc initialized to scale=5
    obase=16
    5465179252
    145C00474
    1170211956
    45C00474

    Displaying the total blocks as Hex may give a clue:

       5465179252 145C00474
       1170211956 45C00474

    [ tru64 Unix hehehe.... ]
