2.12.0 Release Update

  • We are feature complete, so the focus is currently on test plans and execution to those test plans.
  • We are hoping that by end of the month we will have a good read on how we are tracking to final release.
  • We will be scrubbing the 2.12 Jira list soon to only include mandatory items. Non-features that are pushed out can still land if they become ready.
  • Any other updates on 2.12?
    • James: We are hoping to see last ARM bug finished: LU-10300

Upstream Lustre Client

  • Neil has completed the multi-rail port and we been running off of his testing tree.
  • We also pushed some fixes in the LND area. At this point multi-rail pretty much works. We are seeing one bug that isn’t being seen in our branch that we are investigating.
  • At this point, we have ported all bug fixes up to the 2.10.3 release.
  • James will push project quota and PFL stuff soon. Need to break up patches.
  • Cory: Are you doing any performance testing once multi-rail or other new features are pushed in?
    • James: We did some performance testing after the multi-rail changes and are seeing about a 20% performance boost overall.


  • We are formalizing the process of updating all the old HPDD links on the wiki.
  • We will be adding Peter and Andreas to those granted editing rights.
  • Peter: The Lustre wikipedia page is showing old CFS info on the right hand side.
    • Ken will look into it.
