Introduction

Welcome to the Cinder 2023.2 (Bobcat) midcycle summary page!

We conduct 2 midcycles between the OpenStack development cycle (6 months) that acts as a checkpoint for the following:

• Revisiting/following up the topics discussed at PTG
• Discuss topics that were missed during PTG due to author's unavailability or lack of time or any other reason
• Status of work items based on the milestone

There could be more reasons but the above highlighted are the major ones.

For 2023.2 (Bobcat), the Midcycle will happen at:

1. R-18: 31st May, 2023 (Wednesday) 1400-1600 UTC
2. R-6: 23rd August, 2023 (Wednesday) 1400-1600 UTC

We held our second mid cycle of the 2023.2 (Bobcat) development Cycle on 23rd August (R-6 week) between 1400-1600 UTC.

We had a good and productive session mainly focusing on the gate issues we have been noticing recently. We also combined it with the festival of XS reviews.

• Discuss about the broken TGT job
  • We had a problem while running TGT job on Ubuntu Jammy (22.04) environment
  • We decided to discuss about removing the job in 2023.1 PTG
    • https://opendev.org/openstack/cinder-tempest-plugin/src/branch/master/.zuul.yaml#L11-L13
  • #action: We will send a mail to the ML asking if anyone is interesting in keeping the TGT job around and maintaining it. If there are no responses, we will remove the job.

• Upstream job issues
  • We have seen different kind of failures recently in our upstream CI jobs related to:
    • Timeout
    • OOM
  • Currently proposed solution s to run tempest tests with less concurrency
    • Concurrency 3: https://review.opendev.org/c/openstack/cinder-tempest-plugin/+/887377
    • Concurrency 4: https://review.opendev.org/c/openstack/cinder-tempest-plugin/+/891782
  • Other ways to reduce memory consumption from cinder perspective
    • Backup
      • Reduce maximum backup concurrency (currently 15 is default)
      • Reduce chunk size for backups
    • Reduce number of processes for cinder API
    • Reduce memory consumption in MySQL
      • https://github.com/openstack/cinder/blob/ddcf394ae277692d7cab2e03b4b6ae67ba7f1cc3/.zuul.yaml#L176-L178
  • #action: Followup on all the memory enhancements

• Cinder question on the 2024 User Survey
  • Discuss about what changes we should be making to our survey questions
  • Updating the list of supported backends is a good update
    • https://docs.google.com/spreadsheets/d/1YZu7bJ4k_nog4ByrX1KNkjkFHJsIu6c9DM6gGO9R4QU/edit?usp=sharing
  • #action: Brian to update the list of drivers based on support matrix

After that we had a session for Festival of XS reviews where we reviewed os-brick patches for the upcoming release and also discussed other potential import changes.

The list of patches is in the etherpad.
