-   Please note that at most one StorageClass can be marked as default. If two

-   请注意，最多只能有一个 StorageClass 能够被标记为默认。
-   如果它们中有两个或多个被标记为默认，Kubernetes 将忽略这个注解，
-   也就是它将表现为没有默认 StorageClass。
+   请注意，你可以将多个 `StorageClass` 标记为默认值。
+   如果存在多个被标记为默认的 `StorageClass`，对于未明确指定 `storageClassName`
+   的 `PersistentVolumeClaim`，将使用最近创建的默认 `StorageClass` 进行创建。
+   当带有指定 `volumeName` 的 `PersistentVolumeClaim` 被创建时，如果静态卷的
+   `storageClassName` 与 `PersistentVolumeClaim` 上的 `StorageClass` 不匹配，
+   则该 `PersistentVolumeClaim` 将保持在待处理状态。
