<!--
If multiple CSI drivers exist, a default VolumeSnapshotClass can be specified
for each of them.
-->
如果存在多个 CSI 驱动程序,可以为每个驱动程序指定一个默认的 VolumeSnapshotClass。
<!--
### VolumeSnapshotClass dependencies
When you create a VolumeSnapshot without specifying a VolumeSnapshotClass, Kubernetes
automatically selects a default VolumeSnapshotClass that has a CSI driver matching
the CSI driver of the PVC’s StorageClass.
This behavior allows multiple default VolumeSnapshotClass objects to coexist in a cluster, as long as
each one is associated with a unique CSI driver.
Always ensure that there is only one default VolumeSnapshotClass for each CSI driver. If
multiple default VolumeSnapshotClass objects are created using the same CSI driver,
a VolumeSnapshot creation will fail because Kubernetes cannot determine which one to use.
-->
### VolumeSnapshotClass 依赖关系
当你创建一个 VolumeSnapshot 且未指定 VolumeSnapshotClass 时,
Kubernetes 会自动选择一个默认的 VolumeSnapshotClass,
该类与 PVC 的 StorageClass 所使用的 CSI 驱动程序匹配。
这种行为允许多个默认的 VolumeSnapshotClass 对象在集群中共存,
只要每个默认类都与一个且唯一的 CSI 驱动程序关联。
始终确保每个 CSI 驱动程序只有一个默认的 VolumeSnapshotClass。
如果使用相同的 CSI 驱动程序创建了多个默认的 VolumeSnapshotClass 对象,
则创建 VolumeSnapshot 时会失败,因为 Kubernetes 无法确定使用哪个类。
