适用于

  • NetApp Trident CSI(Kubernetes/OpenShift 环境)
  • Trident 版本 25.06.1 及更高版本
  • ONTAP 存储后端
  • Kasten 备份集成
  • 使用具有不同回收策略的多个存储类的环境

问题

将 Trident 从版本 23.04.0 升级到 25.06.2 后,尝试将 PVC(持久卷声明)从源卷克隆到具有不同存储类的目标卷失败。这会影响工作流,例如使用不同存储类(例如,针对不同的回收策略)创建临时卷的 Kasten 备份。

日志输出示例:

Warning ProvisioningFailed 20s (x12 over 5m48s) csi.trident.netapp.io_trident-controller-xxxx failed to provision volume with StorageClass "<StorageClass name>": rpc error: code=Unknown desc=clone volume pvc-xxx from source volume pvc-yyy with different storage classes is not allowed.
