Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Previously, when merging a snapshot to a base RAW volume, the RAW volume was not refreshed. This meant that merging a snapshot that was extended to a RAW base volume when the virtual machine was not running on the SPM would fail. This update ensures that the VDSM refreshes the base volume as needed.	Story Points:	---
