Introduction

This page contains a summary of the subjects covered during the Cinder project sessions at the Project Team Gathering for the Xena development cycle, held virtually April 19-23, 2021. The Cinder project team met from Tuesday 20 April to Friday 23 April, for 3 hours each day (1300-1600 UTC), with Friday's sessions stretching to 4 hours.

The Cinder Team at the Xena (Virtual) PTG, April 2021.


This document aims to give a summary of each session. More context is available on the cinder PTG etherpad:

Greetings and some Cinder project business

Business in no particular order:

  • The final release from stable/train for all deliverables is 12 May 2021, so check for any critical bugs that should be backported and get those moving along right away.
  • We need to do a release from the rbd-iscsi-client to verify that all the tooling is working. Want to do this before any critical bug is discovered that will require a release. The patch formatting rbd-iscsi-client as an OpenStack project still needs reviews: https://review.opendev.org/c/openstack/rbd-iscsi-client/+/774748/
  • There's a patch up placing cinder-specific dates on the OpenStack release schedule. The only notable change from the usual dates is to move the spec freeze to 2 weeks after the R-18 midcycle. (One week didn't give people enough time to revise and resubmit, which required a bunch of spec freeze exceptions. Hopefully we can avoid that this time.) Please check over the dates and leave comments if you see any problems: https://review.opendev.org/c/openstack/releases/+/786951
  • The two midcycles at weeks R-18 and R-9 have been working well, so let's do that again. Format will be 2 hours. I propose holding them in the place of the cinder weekly meeting that week; that way, everyone should be able to attend for at least the one hour they have set aside for the cinder meeting. Time would probably be 1300-1500 UTC. Please check for conflicts:
    • R-18 midcycle: 2 June
    • R-9 midcycle: 4 August
  • Some quick links to be aware of
    • general info on cinder project: tiny.cc/cinder-info
    • cinder group info: tiny.cc/cinder-groups
  • We've got someone interested in helping with documentation. I've asked her to start by reviewing release notes on patches for clarity, grammar, etc. These are user-facing documents so it's helpful to get them correct.
  • We didn't schedule time for a Wallaby Release Cycle Retrospective, so maybe we can do that during happy hour today.
