Description
OST Pool Quotas feature gives an ability to limit user's(group's/project's) disk usage at OST pool.
Each Quota Pool(QP) duplicates content of OST pool. Thus QP could be tuned with standard lctl pool_new/add/remove/erase commands. All QPs are subset of a global pool that includes all OSTs and MDTs(DOM case).
DOM and MDT pools
From Quota Master point of view "data" MDTs are regular members together with OSTs. But until we haven't a mechanism to group MDTs in pools, Quota Pools support only OSTs.
