nova support to enable extension of an attached volume
Currently a volume extension requires that a volume be in the available state. This requires an attached volume to be detached from a VM before the volume can be extended in size.
To address this Cinder will be adding changes to Notify nova when the volume is extended. Nova will be making the necessary changes to trigger a rescan of devices on the host.
