Yes, per primitive, but does not take into account any usage (unless you tell him to do so). > If a node fails, will pacemaker redistribute the resources equally too, e.g. > m * N/(N-1) per node? If you have a 3-node cluster, and one node fails, the dead resources will be distributed equally between the remaining nodes (like said above). > > I don’t see any settings controlling this behavior in the documentation, but > perhaps, pacemaker tries to be “fair” by default. "Utilization" is a good keyword to search. Despite of that there's a German saying "Probieren geht über studieren", meaning "trying is preferrable over studying".
