<div>Also, you might have orphaned Ironic nodes, when node is
available, but still has instance_uuid assigned without actual
instance in Nova. These AFAIK would also not be scheduled to.
To fix it update the node resetting this field</div>

Did that as well, but since the system has been rebuilt, it is hard
to confirm. If we do it again, I'll double check all these. Thanks<br>

Assuming the stack is deleted and nova is showing no
servers, you likely have ironic nodes which are not in a
state which can be scheduled.<br>
<br>
Do an ironic node-list, you want Power State: Off,
Provisioning State: available, Maintenance: False<br>

Yes, we have that. First thing we checked. I assume
"available" is the most important part of that?
