I agree with the strategy Yuriy outlined. This has the added benefit
of mitigating potential future bugs related to callbacks in the task
manager since state "rollback" behavior will be implicitly built into
the task manager.
Details on the potential race condition with provision state change
Hi.
There is state rollback mechanism in ironic if conductor work thread can
not be started for change provision state via API. And looks like we need
the same for
cleaning [1].
This mechanism can not be clearly integrated with provision state
notifications,
in the start -> (end or error) scheme
