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:	---

 Verified with the following code:
------------------------------------------
vdsm-4.18.15.3-1.el7ev.x86_64
rhevm-3.6.10-0.1.el6


Verified with the following scenario:
------------------------------------------
1. Create a VM with 1gb preallocated disk in a block-based domain.
2. Create a snapshot.
3. Extend the disk to 2gb.
4. Start the VM.
5. Delete the snapshot.

* Tested on HSM and SPM host.

Moving to VERIFIED!
