2.9 Release Status/Update

  • The number of blockers is slightly up from last week, however, some are just interop issues due to recent landings.
  • The largest item to close out on is SSK development. There have been a number of suggestions for implementation change made by Intel security experts. Those changes have been made and are queued up for testing and landing.
  • Anything else to report from the community?
    • No word of any other focused 2.9 testing by the community due to other priorities.

2.10 Release Update

  • Once we branch when reaching code freeze for 2.9, we can begin looking at 2.10 landings.
  • There is a feature test plan template that cased be used for feature development in the 2.10 cycle.

Upstream Lustre Client

  • The 4.9 release is going to be a 2.7 client equivalent. There was ~120 patch delta between 2.6 to 2.7.
  • After the next merge window James is looking to try out 2.8 patches. James has had a rough look at ~1/4 of the code and there are ~40 patches thus far that will be needed.
  • Will the kernel go to 4.10 numbering after 4.9?
    • James: I believe that it will.


  • The Mediawiki upgrade is occurring.
  • We are getting close on the old wiki migration.
  • There are about 70 old architecture documents and there is uncertainty about how to handle them. The current plan is to preserve them as static pages.
    • Peter - I would be concerned about having stale references on the architecture page, but agree that we should keep it available. Perhaps the creation of a historical architecture documents area would be appropriate to retain the documents, but with a warning that data may be stale.
      • All present agree.

Other Business

  • Sarp: organizational changes in OpenSFS
    • We are now officially operating under a new set of bylaws and a new board composition.
    • The new board consists only of Lustre users (no vendors).
    • Sarp has accepted a role on the board and, therefore, is stepping away from the LWG co-chair role.
    • Dustin Leverman of ORNL will be taking on the co-char role as Sarp’s replacement.
    • A “save the date” announcement will be coming soon for LUG. The event will be hosted by Indiana University this year. More details to come in the announcement.
    • A reminder that the OpenSFS board meetings are open to the public and anyone can attend that is interested.

Next meeting will be on 2016-10-19
