The cinder.scheduler.weights.volume_number Module

class VolumeNumberWeigher

Bases: cinder.scheduler.weights.BaseHostWeigher

Weigher that weighs hosts by volume number in backends.

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.

weight_multiplier()

Override the weight multiplier.
