#3733 system-status: incorrect reporting of disk space
http://localhost:10000/right.cgi?open=system&open=status seems to display inaccurate values for disk space:
Local disk space 458.33 GB total, 33.24 GB used
Expected to see instead: ~10 GB disk space used.

I just saw - hooray for ext accounting its data structures :-/
The real issue here is that by default, ext filesystems reserve 5% of space for root, and Webmin counts that as used (because total - free = 33G). You can adjust this with the tunefs command though.
