[cobalt-users] Q. on Disk Usage of individual users

[bert_catsburg <bert_catsburg@xxxxxxxxxx>]

Hello experts,

Browsing through KB and this list, I couldnot find this question
I am having:

We have several sites set up on our RAQ2+.
For the sake of the example, the site is called: www.mysite.com
Users are called: Joe and Jim.

If we make Joe the siteadmin, then all files are owned by Joe and are
in the group 'site<number>'.

Now it happens that we check Disk Usage for the users and we see
that the siteadmin has 5 Mb,  Joe has 2 Mb and Jim has 1 Mb.
All users do not have email usage in /var/spool/mail.

Questions are:
- The 5Mb, how is this calculated? 
  Is this the usage in /home/sites/siteX/web which is owned
  by Joe?
- Where can I find the 2 Mb Joe owns?
  (And where the 1 Mb Jim owns?)
- How does Disk Usage utility make the distinction between
  files for the site-admin and files for Joe?

Thanks for your help,

Bert Catsburg
