It should not return anything which means the volume is not attached to any server although it shows in-use state. Therefore, it's safe to proceed with resetting the volume state to available.
$ docker exec -it galera-bundle-docker-0 mysql cinder -e "select * from volume_attachment where volume_id='<Volume_UUID>' \G;"
