The cinder.scheduler.weights.capacity Module

Capacity Weigher. Weigh hosts by their available capacity.

The default is to spread volumes across all hosts evenly. If you prefer stacking, you can set the ‘capacity_weight_multiplier’ option to a negative number and the weighing has the opposite effect of the default.
