Description

OST (or MDT) pool feature enables users to group OSTs together to make object placement more flexible which is a very useful mechanism for system management. However the pool support of quota is not completed now which limits the use of it. Luckily current quota framework is really powerful and flexible which makes it possible to add new extension.

We believe that pool support of quota will be helpful for a lot of use cases, so we are trying to complete it. With the help from the community, we've made some progress. The full patch will be a big one which involves quite a lot of components of Lustre. Any advice or feedback about the implementation will be really helpful.
