Re: df and du contradict

I've seen the same problem under FreeBSD too, with a dedicated webserver,
the hosting company mounted /bob (what's it for anyways, no clue), and it
has this:

raveni# df -h
Filesystem    Size   Used  Avail Capacity  Mounted on
/dev/da0s1a   388M    27M   330M     7%    /
/dev/da0s1f   6.6G   4.5G   1.6G    74%    /usr
/dev/da0s1e   775M    94M   619M    13%    /var
procfs        4.0K   4.0K     0B   100%    /proc
/dev/da1s1e    33G    15G    15G    50%    /www3
/dev/da2s1e   8.3G   7.0G   675M    91%    /www2
/dev/wd0s1e   9.3G   9.3G -753.5M   109%    /bob
raveni#

and when I do du -h -s /bob it just takes forever, I guess since /bob is
so large.
