Overview

Package admin is a convenience layer to support the administration of CephFS volumes, subvolumes, etc.

Unlike the cephfs package this API does not map to APIs provided by ceph libraries themselves. This API is not yet stable and is subject to change.

This package only supports ceph "nautilus" and "octopus" at this time.
