KubePodNotReady 警报以及在 OpenShift ADP 备份 Pod 中出现 context deadline exceeded 错误,使用 NetApp Trident
适用于
- NetApp AFF / ONTAP 系统(ONTAP 9.x,集群模式)
- Red Hat OpenShift 带 ADP(应用程序数据保护)操作员
- NetApp Trident CSI 驱动程序
问题
- 由 OpenShift ADP operator 创建的备份 pod 无法达到 Ready 状态,并触发 KubePodNotReadyalerts。虽然 PVC 和 PV 绑定成功,但 pod 事件显示:
Warning FailedAttachVolumeAttachVolume.Attach failed for volume "pvc-<uuid>": rpc error: code=DeadlineExceeded desc=context deadline exceeded
- Trident 日志反复报告与快照删除相关的错误:
Could not delete the snapshot... snapshot <name> has not expired or is locked
snapshot ... is busy
GRPC error: snapshot backing volume ... is busy
