适用场景

  • OpenShift/Kubbernetes
  • SAN/iSCSI PVs
  • NAS PWO PV
  • 三项功能

问题描述

如果使用PV的原始Pod在其节点上发生故障或被删除、并且Kubenetes尝试在其他某个节点上启动它、而该Pod使用基于RUP的PVC (例如使用iSCSI ontap-san 后端的PVC)、但同时使用NFS RwO类型PV、则替代Pod会发生以下错误:

Multi-Attach error for volume "pvc-<UUID>" Volume is already exclusively attached to one node and can't be attached to another

但是、一段时间后、剩下的唯一错误是:

Warning FailedMount <time_delay> kubelet MountVolume.MountDevice failed for volume "pvc-<UUID>" : rpc error: code = DeadlineExceeded desc = context deadline exceeded
