When I run the command df -h on my new Ubuntu linux vServer I get the following:

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hdv1             466G   33G  434G   7% /
none                   16M     0   16M   0% /tmp

Running du -sh gives

# du -sh 
du: cannot access `./proc/13624/task/13624/fd/4': No such file or directory
du: cannot access `./proc/13624/task/13624/fdinfo/4': No such file or directory
du: cannot access `./proc/13624/fd/4': No such file or directory
du: cannot access `./proc/13624/fdinfo/4': No such file or directory
952M    .

The VPS should only have 5Gb of disk space but df reports 466Gb. How can I view the correct amount of disk space?
