Well, for starters, du -sk suffers from some of the same problems - large numbers of nfs getattr calls (I'm not entirely sure that it does exactly the same thing, but it's got to count filesizes somehow).
The second is, we were looking for some flexibility in the system. The 'top level' is owned by the customer, but the lower levels by each of the departments. We need to aggregate the results of the du accordingly. Of course, du -sk /fs001/* followed by 'for i in `ls /fs001`; do du -sk /fs001/$i/*;done' would provide approximately similar results (until we reached the point of 'polluted' directories), but the problem is then you are running a du _twice_. We are talking approx 2.5 Tb of data, and so I'd rather avoid doing it that way.

It's not pessimism if there is a worse option, it's not paranoia when they are and it's not cynicism when you're right.
