Volume manage extension (os-volume-manage)
==========================================

Creates volumes by using existing storage instead of allocating new
storage.


Manage existing volume
~~~~~~~~~~~~~~~~~~~~~~

.. rest_method::  POST /v2/{tenant_id}/os-volume-manage

Creates a Block Storage volume by using existing storage rather than allocating new storage.

The caller must specify a reference to an existing storage volume
in the ref parameter in the request. Although each storage driver
might interpret this reference differently, the driver should
accept a reference structure that contains either a source-id
or source-name element, if possible.

The API chooses the size of the volume by rounding up the size of
the existing storage volume to the next gibibyte (GiB).
