Greetings to anyone developing a new Cinder driver (or target driver), or anyone trying to get someone to develop such a driver,
This is a reminder that the deadline for merging a new backend driver or a new target driver to Cinder for the Ussuri release is the Ussuri-2 milestone on 13 February 2020 (23:59 UTC). New drivers must be (a) code complete including unit tests, (b) merged into the code repository, and (c) must have a 3rd Party CI running reliably. (The idea is that new drivers will be included in a release at the second milestone and thus be easily available for downstream testing, documentation feedback, etc.)
You can find more information about Cinder drivers here: https://docs.openstack.org/cinder/latest/drivers-all-about.html and you can ask questions in #openstack-cinder on IRC or here on the mailing list.
cheers, brian
