Hello everyone, thanks for a very productive PTG for the Gazpacho cycle. Below is a brief summary of the highlights. The raw etherpad notes are here [1] and both the summary and transcribed etherpad notes are captured in out wiki here [2]. # Retrospective We spent time discussing the good and not-so-good of the flamingo cycle. Unsurprisingly, code reviews continue to be our most significant opportunity for improvement. We reviewed what a core reviewer is and how to work towards becoming one, including the metrics that we use to determine eligibility and what we look for in a potential core reviewer. I encourage anyone interested in contributing the project to reach out, in addition to our guideline document on the review process, we're happy to answer questions and help guide folks through the process. # Festival of Reviews We are reworking our 'festival of reviews' meeting to better accommodate a larger set of potential patches. Previously it focused on very small patches that were easier to review, but feedback suggests that time spent as a team on larger reviews would yield a more desirable result. Last Friday we ran the modified format and it seemed to work quite well. # 3rd Party CI This cycle 3rd party CI is required for patches to be reviewed. In the flamingo cycle we saw some challenges with deploying and configuring the software factory setup required to operate a CI. We remain committed to helping vendors sort out any remaining problems, and want to avoid any further slipping on our requirements, as one-off exceptions do not scale. # Eventlet Removal There will be significant focus this cycle on the removal of eventlet from our codebase. Our goal is to have this work completed before M2. The remaining issues and technical challenges were discussed, including some struggles with our multi-backend and it's use of sqlalchemy. We learned that the oslo team is working on some code that may help with this effort. We may have finally found a use for the rally job, unfortunately it has been broken for some time, we will try to get this fixed and reporting useful results this cycle as well. # Driver Block Geometry An original patch to the RBD driver was proposed to make configuring block geometry an option for the operator. Upon inspection, we decided make this option available for all drivers. Discussion about exact location given out driver class model, we have a way forward. https://review.opendev.org/c/openstack/cinder/+/658283 # Per-Tenant SVM Creation Doug Goldstein showed up and blew our minds with a proof-of-concept feature he added to the NetApp driver. This change allows the driver to create per-tentant SVMs and map them to dynamically created backends. There will be some technical hurdles to overcome, but the idea in theory could work. Doug is going to work to propose a patch upstream and with the NetApp team to see if it can take shape. # OpenAPI Stephen has had patches up for openAPI compliance for far too long. We don't have any technical objections to the effort. Brian and I committed to working through the proposed patches at the very start of the cycle. Significant progress already, should be completed soon. # Reverting To Any Snapshot Currently you can only roll a volume back to the last available snapshot. We would like to be able to select any snapshot as a rollback target. Technical requirements were discussed, including the need for a spec. Hoping to see progress on this effort in this cycle. # Clone Across Pools We are interested in improving our implementation for cloning a volume across different pools. The code itself has some distinct shortcomings and Rajat identified several opportunities for improvement. Feedback on current usage was requested, we discussed volume caching as part of these improvements. A path forward was defined and spec should follow. # NFS Driver Feedback Fernando has been working on several improvements to the generic NFS driver and requested feedback. NetApp offered valuable suggestions, some improvements to our tempest testing patches are forthcoming, and a direction forward is understood. # Replication Feedback We solicited feedback on replication, its current usage, and the features it may require to see wider adoption. Questions and answers were discussed, hoping to see a spec capturing the most valuable changes in this cycle.
