Introduction

Welcome to the Cinder 2024.1 (Caracal) 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 2024.2 (Caracal), the Midcycle will happen at:

1. R-17: 6th December, 2023 (Wednesday) 1400-1600 UTC
2. R-7: 14th February, 2023 (Wednesday) 1400-1600 UTC

We held our first mid cycle of the 2024.1 (Caracal) development Cycle on 6th December (R-17 week) between 1400-1600 UTC.

• Retiring cinderlib
  • Etherpad: https://etherpad.opendev.org/p/cinderlib-retirement
  • Major consumers of Cinderlib are Ember-CSI and oVirt
    • They are happy with old releases of cinderlib and don't require new development work into it
  • We will not transition to 2024.1 (Caracal) development
  • We will not accept any new patches in cinderlib
  • We will support the last 3 stable releases i.e. 2023.2, 2023.1 and Zed (approximately 18 months)
  • EM branches will transition to Unmantained (Victoria -> Yoga)
  • #action: rosmaita to follow up on work associated with the deprecation
• Rework of JovianDSS Driver
  • Patch: https://review.opendev.org/c/openstack/cinder/+/889284
  • Refactoring of an old driver
  • #action: Review the patch

• NFS online extend
  • Blueprint: https://blueprints.launchpad.net/cinder/+spec/extend-volume-completion-action
  • Patches in order of dependency
    • https://review.opendev.org/c/openstack/cinder/+/873557
      • Add the os-extend-volume-completion volume action
    • https://review.opendev.org/c/openstack/python-cinderclient/+/873558
      • Support the new volume action in python-cinderclient
    • https://review.opendev.org/c/openstack/nova/+/873560
      • Make Nova use the new volume action when handling "volume-extended" events
    • https://review.opendev.org/c/openstack/cinder/+/891602]
      • Make the new feature available for volume drivers
    • https://review.opendev.org/c/openstack/cinder/+/873686
      • Add support in the NFS driver
    • https://review.opendev.org/c/openstack/cinder/+/873889
      • Add support in the Netapp NFS driver
    • https://review.opendev.org/c/openstack/devstack-plugin-nfs/+/896196
      • Enable attached volume extend tests in devstack-plugin-nfs-tempest-full
  • Slides to explain the current workflow and the changes going to be made by the feature
    • https://github.com/kgube/cinder-2024.1-midcycle-1/blob/main/nfs_online_resize.pdf
  • #action: review the patches (at least ones that are blocking nova side reviews)

• acceptable usage of `__init__()` in os-brick
  • Patch: https://review.opendev.org/c/openstack/os-brick/+/887576
  • Eric's concern is that this code in __init__ shouldn't affect other brick connectors
    • by failing initialization of other connectors
    • by holding the initialization for too long (a heavy weight call to backend)
  • The above concerns shouldn't be an issue in this case
  • #action: document standards for working on os-brick connectors

• CI Monitoring
  • Etherpad: https://etherpad.opendev.org/p/cinder-caracal-ci-tracking
  • Lately we have been facing too many CI issues
  • There are also issues reported from Nova and Glace team for some cinder related failures
  • The actions to fix the CI have mostly been reactive so it would be better to monitor the CI proactively
  • Jon Bernard volunteered to actively monitor our CI and integrate it in weekly bug report status
  • cinder-tempest-plugin-cbak-s3 history has also been consistently failing
    • https://zuul.opendev.org/t/openstack/builds?job_name=cinder-tempest-plugin-cbak-s3
  • swap space increase patch to make gate stable
    • https://review.opendev.org/c/openstack/cinder-tempest-plugin/+/901672
  • #action rosmaita - get info from infra team about the nodepool nodes and what kind of control we have over configuration from the zuul side
  • #action whoami-rajat: check the blocker for concurrency effort - talk to Luigi as he was working on it some time ago
• Supporting AND operation on time comparison filters
• Several patches to the StorPool Cinder driver
