Doc Text:
Feature: Volume affinity in OpenShift Reason: Cloud providers typically use multiple zones/regions for their virtual machines and storage offerings. A virtual machine in one zone/region can only mount storage from the same zone/region in which it resides. OpenShift pods that use cloud storage must be scheduled onto virtual machines in the same zone/region for their associated storage; otherwise, the pods will fail to run. Result: Pods are scheduled to the same zone/region as their associated storage. Note, if you are not using the default scheduler configuration, you need to ensure that the NoVolumeZoneConflict scheduler predicate is enabled in your scheduler configuration file in order for volume affinity to function correctly.
