--- features: - | Adds power failure recovery to ironic. For nodes that ironic had put into maintenance mode due to power failure, ironic periodically checks their power state, and moves them out of maintenance mode when power state can be retrieved. The interval of this check is configured via ``[conductor]power_failure_recovery_interval`` configuration option, the default value is 300 (seconds). Set to 0 to disable this behavior. upgrade: - | Power failure recovery introduces a new configuration option ``[conductor]power_failure_recovery_interval``, which is enabled and set to 300 seconds by default. In case the default value is not suitable for the needs or scale of a deployment, please make adjustment or turn it off during upgrade. - | Power failure recovery does not apply to nodes that were in maintenance mode due to power failure before upgrade, they have to be manually moved out of maintenance mode.
