Fixed In Version:	openstack-heat-8.0.2-2.el7ost	Doc Type:	Bug Fix
Doc Text:	Cause: Cinder requires an extra flag to force allowing a snapshot of a volume that is IN_USE. Heat did not pass that flag when doing "stack snapshot create". Consequence: Creating the snapshot failed if the stack contained any volumes that were in-use. Fix: The force flag is now passed to Cinder when creating the volume snapshot. Result: Stacks containing volumes that are in-use can now be snapshotted.	Story Points:	---

Description Thomas Hervé 2017-06-15 11:27:49 UTC

+++ This bug was initially created as a clone of Bug #1438137 +++

Description of problem:

I tried to create heat stack snapshot for the stack in which instance is
booted using cinder volume. It got failed because of cinder volume
IN_USE state. I don't see any option from heat to force the snapshot
creation. It looks like a bug.

Version-Release number of selected component (if applicable):
RHEL OSP 10

How reproducible:
Everytime

Steps to Reproduce:
1. Spawn an instance using stack which is boot from cinder volume
2. Tried to take the snapshot of the heat stack. It's getting failed because volume is IN_USE. 
3. We can use the cinder force option to take the snapshot of IN_USE volume but this option is not available with heat snapshot. 

Actual results:
Not able to take the snapshot of heat stack. 

Expected results:
We should be able to take the snapshot of heat stack.
