Tried to create a snapshot of the heat stack overcloud (from a new clean state).<br>
The snapshot is stuck IN PROGRESS (for over an hour). I cannot remove it.<br>
Perhaps this is not such a good/reliable method.<br>
I will revert to my CloneZilla bare metal imaging to restore back.<br>
<br>
Any other suggestions as to how to cope with a stack update failure without deleting and recreating the stack?<br>
<br>

Hi,<br>

I am testing expanding my stack by adding more compute nodes. The first update failed, leaving the overcloud stack in a failed state.<br>
Is it best practice to create a snapshot of the overcloud heat template before updating the stack?<br>
You could then roll back and try the update again.<br>
<br>
heat stack-snapshot overcloud<br>
heat stack-restore [snapshot-id]<br>
