Hi Matt, Andrey,
CERN-BARC team was working on nested quota
implementation in Nova some 3 years back.But at that time, it was decided to
fix bugs in the existing quota driver rather than adding more features. After
that , the Cinder team implemented nested quota in Cinder and at the same time,
there was a plan to implement a quota library called Delimiter.

Unfortunately things have not progressed much.Actually,the
main hurdle is the delay in having a concrete decision in the approach that
needs to be adopted.While it is accepted that, there should be a common entity
for quota management of various services like Nova, Cinder, Neutron, it has not
been finalized whether that common entity should be a library or a separate
service itself.Both approaches are having its own pros and cons. But the main
point is that we need to take a concrete decision in the approach that needs to
be adopted, to make the things move forward.So IMHO it would be nice to have a
discussion on hierarchical quotas at the PTG.
best regards,
sajeesh
Thanks for the details.
I've posted hierarchical quotas as a discussion item in the Arch WG
session at the PTG:
