deprecations:
  - |
    The ``<volume-group-type>`` and ``<volume-type> [<volume-type>...]``
    positional arguments for the ``volume group create`` command have been
    deprecated in favour of option arguments. For example::

        openstack volume group create \
          --volume-group-type <volume-group-type>
          --volume-type <volume-type> [--volume-type <volume-type> ...]
