适用场景

  • NetApp三项功能
  • 带有 CDI(容器化数据导入器)的 OpenShift 虚拟化

问题解答

此行为是由于 OpenShift Virtualization/CDI 中的PVC 克隆逻辑造成的:
•VM 是从模板创建的,该模板使用最初使用 ontap-san-economy 驱动程序创建的 DataVolume 或 PVC。
•即使新的 PVC 指定不使用 onta-san 驱动程序的存储类,克隆操作也会引用原始卷的数据源(DataVolume)——它仍然保留来自 ontap-san-economy 的元数据。
•Trident 通过尊重原始卷的后端来处理克隆,从而将克隆的 PVC 放置在后端(ontap-san-economy)下,尽管指定了 StorageClass。
