The cinder.scheduler.weights.volume_number Module

Weighers that weigh hosts by volume number in backends:

1. Volume Number Weigher. Weigh hosts by their volume number.

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

Bases: cinder.scheduler.weights.BaseHostWeigher
