Open Stack

Well I just tested this....

Tried to create a snapshot of the heat stack overcloud (from a new clean 
state).
The snapshot is stuck IN PROGRESS (for over an hour). I cannot remove it.
Perhaps this is not such a good/reliable method.
I will revert to my CloneZilla bare metal imaging to restore back.

Any other suggestions as to how to cope with a stack update failure 
without deleting and recreating the stack?

Thanks

Charles
