适用于

  • NetApp ONTAP(All Flash FAS、AFF-C800 及类似产品)
  • 适用于 Kubernetes 的 Trident CSI 驱动程序
  • 使用 NetApp 持久卷的 Kubernetes 集群

问题

依赖 NetApp 持久存储的 Kubernetes Pod 仍然处于异常状态(例如 TerminatingBackOff),并且在后端 NetApp 存储离线时(例如,由于控制器死机和 LUN 进入 nvfail 状态)无法正常删除或恢复。

日志输出/症状示例:

  • Pod 长时间保持 Terminating 状态。
  • 如果卷装载尝试反复失败,Pod 进入 BackOff
  • 群集事件显示卷卸载失败或无法访问存储。
  • 存储控制器日志指示 LUN 处于 nvfail 状态且后端服务离线。
