[LU-4017] Add project quota support feature

• Type: New Feature
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.10.0

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.

Yes. That is true at this point. We are scoping out what is required to extend this work further.

[James A Simmons]

Yes it appears this is not supported on any SLES systems as well. Project Quota appears to only be supported on RHEL systems with ldiskfs

[Bob Glossman (Inactive)]

Does support for this new feature only exist on el7 servers with ldiskfs?

[James A Simmons]

I just noticed with this work its no longer possible to have patchless kernels for lustre server side.
