Introduce a distributed node cache sync between ironic and inspector. See the HA Spec[1] for implementation details. [1] http://specs.openstack.org/openstack/ironic-inspector-specs/specs/HA_inspector.html#ha-singleton-periodic-task-decomposition
This step will most likely not be included; the instances are OK each running a local periodic task syncing the node-info records through the shared DB. Closing for now.
