> On the cluster where some nodes are in the maintenance mode Add Service
> Wizard doesn't track this.
> So, user may select host in the maintenance mode to install some master
> component. And this component won't be installed (only record in the DB will
> be created for it).
> Another situation:
> there is some cluster where all nodes are in the maintenance mode. In this
> case ASW is almost useless. Because all new components won't be installed
> while it works.
> Maybe ASW should track hosts in the maintenance mode and warn user about
> adding components on them (Steps "Assign Masters", "Assign Slaves and
> Clients")? Or just don't allow to do this?
