As per Cinder code, following parameters are not required to be passed in the request body of create volume API. * status * user_id * attach_status * project_id * source_replica If you pass these parameters, previously it was ignored but in the schema validation changes[1] we don't allow additionalProperties to be passed in the request body. If user passes additional parameters which are not as per API specs[2], then it will be rejected with 400 error. On patch[3], tempest tests: test_volume_snapshot_create_get_list_delete, test_volume_create_get_delete" are failing because of these unnecessary parameters. This patch removes these unnecessary parameters passed to the create Volume API.
