 Description   

While the new quota architecture was developed with DNE in mind, some more work will still be required to support DNE once it is ready to land onto master (DNE was developed in a separate branch). This includes:

  • sharing the connection to MDT0 with FIDonOST
  • having one single connection between MDTs which can be used by both cross-MDT operations and quota acquire/release
  • change sanity-quota.sh to support DNE
  • add more test cases to exercise quota + DNE

Johann, can you try to come up with a rough sizing on this work? I'll need to know who to allocate for this and how long they will need to build these features. Thanks.
