Many/most clustered systems need to specify anti-affinity for new storage. Imagine a MySQL cluster where all volumes end up on the same external storage device. May leverage concept in https://github.com/container-storage-interface/spec/issues/7

Alternatively, if a Container needs to access multiple Volumes then they must be created in such a way that they can both be mounted by the same node at the same time. See https://github.com/container-storage-interface/spec/issues/43
