适用场景

适用于 Kubernetes/Openshift 的 Trident

问题描述

ontap-nas-economy 同一 SVM 上使用 Kubernetes 或 OpenShift 集群从两个 Trident 使用时,创建此 PV 的基础卷可能会从另一个集群导出,从而导致access denied创建的 Pod 出现 " " 错误。
 
例如, SVM 具有两个通过 ontap-nas-ecnomy 创建的卷,其中一个集群的导出为一个,另一个集群的导出为另一个:
trident_qtree_pool_trident_XGNOGQKASX, exported with policy ClusterA
trident_qtree_pool_trident_ZGKVFHAMCS, exported with policy ClusterB
 
Trident 为集群 A 创建的新 PV 会创建为一个 qtree ,并启用配额 trident_qtree_pool_trident_ZGKVFHAMCS ,并 ClusterA 具有自己的导出。
由于导出过程仅通过导出到的卷根导出 ClusterB ,因此会拒绝从集群 A 节点进行访问。
