By default, the Ceph Distributed File System puts file metadata in the pool "metadata", and file contents in the pool "data". RBD images, by default, are stored in the pool "rbd". This means you can empty/remove the pools "metadata" and "data" without affecting RBD. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
