> Affects Versions: 2.4.0

> Even if a service or component is set to auto start but is in maintenance
> mode, it should not auto start. Components in maintenance mode (because
> host/service is in maintenance mode) should not be enabled for auto start.
> Current implementation:
> In the current implementation we have both enabledComponents and
> disabledComponents. To determine if a specified component is enabled for
> recovery, an inclusive and exclusive test against enabledComponents and
> disabledComponents is used. There is no support for excluding a component in
> maintenance since that state is not available to the agent.
> To determine if a component marked for auto start is in maintenance state,
> it's maintenance state has to be queried from the server, which makes it
> cumbersome and agent managed.
> New design:
> 1. Components to be enabled for auto start must be explicitly specified as
> comma separated values in the enabledComponents section of the recovery
> configuration.
> 2. During agent registration, the server will determine if each of the
> components marked for auto start is in maintenance mode or not and filter the
> list before sending the list (enabledComponents) in the recovery
> configuration to the agent.
