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