适用于

  • NetApp Trident(CSI 驱动程序)
  • NetApp ONTAP 9.17.1P2
  • OpenShift 4.19.x / Kubernetes 1.32.x
  • Rubrik 备份与 Trident 管理的 PVC 集成

问题

mas-masprd-core 命名空间的 Rubrik 备份在 Trident 管理的 PVC 上失败。多个 Trident 节点 Pod 处于 CrashLoopBackOff 状态,Pod 日志显示就绪探测失败:

Readiness probe failed: HTTP probe failed with status code: 503

示例 pod 状态:

trident-node-linux-5jr6f 0/2 CrashLoopBackOff ...trident-node-linux-69lhc 0/2 CrashLoopBackOff ......

此外,在相关卷上观察到许多快照的挂起和成功删除操作。由于这些 Trident pod 故障,Rubrik 无法完成备份。
