适用于

  • NetApp Trident CSI 驱动程序
  • 通过 Trident 使用 NetApp SAN 存储的 Kubernetes/OpenShift 集群

问题

客户可能会在通过 Trident 连接到 NetApp SAN 存储的 Linux 主机上观察到以下内核消息和多路径事件,特别是在计划的自动化作业(例如,合规性扫描)期间:

日志输出示例:

[Wed Jul 1 01:00:09 2026] sd 5:0:3:7: Power-on or device reset occurred [Wed Jul 1 01:00:09 2026] sd 5:0:3:7: LUN assignments on this target have changed. The Linux SCSI layer does not automatically remap LUN assignments. [Wed Jul 1 01:00:48 2026] sd 12:0:3:4: LUN assignments on this target have changed. [Wed Jul 1 01:00:50 2026] sd 12:0:2:1: LUN assignments on this target have changed.

报告的症状:

  • 计划时间内的主机 I/O 超时、路径故障转移或 LUN 离线事件
  • 多路径错误,例如no_path_retry queue|fail|#
  • 发生时间与夜间或计划的 Kubernetes PVC 配置/取消配置(例如合规性作业)相吻合
  • 未对存储端的 LUN 映射进行手动更改
