--- upgrade: - | The Nexenta Edge storage driver has been removed after completion of its deprecation period without a reliable 3rd Party CI system being supported. Customers using the Nexenta Edge driver should not upgrade Cinder without first migrating all volumes from their Nexenta backend to a supported storage backend. Failure to migrate volumes will result in no longer being able to access volumes back by the Nexenta Edge storage backend. other: - | The Nexenta Edge storage driver was marked unsupported in Stein due to 3rd Party CI not meeting Cinder's requirements. As a result the driver is removed starting from the Train release.
