2.12.0 Release Update

  • Oleg has continued with landings and is testing more patches in master-next.
  • Any report out on any testing efforts with current master?
    • Cory: We have picked up our testing effort on master, but nothing serious found. Things are looking pretty good at the moment.

Upstream Lustre Client

  • We have had follow-on discussions to the recent events of being removed from staging and those conversations are going well.
  • Cory: Are we all satisfied with this approach of Neil hosting on GitHub?
    • Peter: If Neil is putting in the time, it makes sense for him to dictate some things around setup since he is part of the kernel circle.
    • James: The reason I support it is because I feel we can move much faster. The Intel branch moves slower and harder to work with for this purpose.
      • Peter: Yes, however, the priority on that branch is that we are always trying to keep it functional and working properly.
    • Andreas: The problem with this approach is that all the feature work will have to be redone on the GitHub branch. That is all of multi-rail, PFL, FLR, recent LFSCK improvements, etc... It is probably over 100K lines of code that will need to be reviewed again in this approach. It seems like resources are going to be a hurdle with that approach.
    • Andreas: Why not use the newer tree if we are not that far off?
    • James: It isn't worth the effort to do the rebase, we are not that far off and James/Neil believe velocity will be faster with this approach.
    • Andreas: One of the dangers of this approach is that if James/Neil/others spend a ton of time on the GitHub branch and it still takes a year or more to get into the kernel. You will then have to either spend a ton of time syncing back and forth or the GitHub branch becomes out of date and we are back into a similar position.

Ken Rawlings

  • Finalizing the old wiki migration remains a priority.
  • The next steps is to work on the guidelines page with Shawn Hall.
  • Cory: John Hammond maintains a patch status page. Is that page documented as a tool on lustre.org as part of the development process? If it is not, then we should remind people of this.
    • Ken: I will review the instructions and get it in there if it is missing.

Other Business
