A Domain Administrator is created and assigned a quota of 1000MBs and
the ability to create 10 end users. The Domain Administrator now has
the
ability to create 10 users whose total, combined quotas are
"constrained" to 1000MBs. The end users quotas are not in addition to
the Domain Admins quota but rather constrained by it.
I think Ricardo's point is that you are correct up until the
last sentence. You would end up with:
DA 1000 MB
User1 100 MB
User2 100 MB
(...)
User10 100 MB
Now if all ten users have maxed out their quota what prevents the DA
from uploading files? Nothing. Unix only tracks quotas on a per-user
basis. Group quotas only apply to files "group owned" by the group, not
to files owned by members of the group. Hence the effective maximum disk
space that is theoretically able to be used is 2000 MB.
Put another way the following scenario is not possible with CPX:
DA 200 MB
User1 100 MB
User2 100 MB
(...)
User10 100 MB
CPX prevents you from creating users that would exceed the DA's quota,
however, at one point it would do so without any sort of indication or
error message, and simply return to the previous "edit user" screen. I
haven't tried lately so I don't know if that's fixed.
