I am not sure I understand what this bug is about. Resource updates (updatest to the  in Essex are done through notifications and the capacity_notifier needs to be set in the notification_driver flag in the nova.conf as it is not used by default.

Folsom does not have this problem as the resource tracker has been implemented at that time and the tables are updated correctly on every action.

I will close it as not a bug.

Comment 3 Dan Yocum 2013-01-04 23:54:10 UTC
What's the correct value to set notification_driver to?  The default is nova.notifier.no_op_notifier.

Thanks

Comment 4 Nikola Dipanov 2013-01-05 13:49:29 UTC
The value of the notification_driver if you want the compute_nodes db table to be updated should be:

nova.notifier.capacity_notifier

This makes sense only in Essex - this does not exist in Folsom anymore as the updates are done automatically.
