Not technically a CSI issue but filling it there so that it ends up in the shiftstack team bucket.
A recent pull request  triggered a bug that caused the in-tree cinder provisioner to fail with the following error:
PV Create API error: persistentvolumes "cinder-" is forbidden: error querying Cinder volume 931c49d9-f363-40b1-9e2c-d3c8a280281c: unable to initialize cinder client for region: RegionOne, err: cloud provider is not initialized: secret lister is not initialized occurred
This is consistently failing in-tree cinder operations as shown by the 4.8 periodic jobs , so giving this an urgent severity.
Verified as the job-history started to pass since the fix is merged (first pass observed on "2021-04-29 18:00:36 +0000 UTC"):
