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.
