An administrator can mark a specific `StorageClass` as default by adding the

When a default `StorageClass` exists in a cluster and a user creates a
`PersistentVolumeClaim` with `storageClassName` unspecified, the
`DefaultStorageClass` admission controller automatically adds the
`storageClassName` field pointing to the default storage class.

在[多可用区](/zh-cn/docs/setup/best-practices/multiple-zones/)集群中，Pod 可以被分散到某个区域的多个可用区。
单可用区存储后端应该被制备到 Pod 被调度到的可用区。
这可以通过设置[卷绑定模式](/zh-cn/docs/concepts/storage/storage-classes/#volume-binding-mode)来实现。
