One is an offline node and the other is one with a number higher than the config option allows. Although we do have a concept of possible nodes N_POSSIBLE I do not think we do enforce that in any user interface and we only reject nodes outside of MAX_NODE. The possible nodes concept is more about optimizing for real HW so that we do not over shoot when the config allows a huge number of nodes while only handful of them are actually used (which is the majority of cases). -- Michal Hocko SUSE Labs
