适用场景

  • ONTAP 9.7
  • ONTAP 9.8
  • SVM DR关系已断开

问题描述

  • 策略类型为 mirror-vault 的 SVM-DR 可能会丢失数据
  • SnapMirror 策略中的 Keep 值可在目标上保留更多快照

例如源上的 Snapshot 策略会保留 5 个每小时快照,而 SnapMirror 策略会在目标上保留 50 个每小时快照

  • SVM-DR断开后、已复制到目标的源 卷上的快照策略在目标卷上变为活动状态
  • 使用上面的示例,如果允许在目标上启动快照计划,则每小时快照将被删除,并且仅保留 5 个快照

注意: 只有在运行快照计划时,才会删除快照,而不是在运行 SnapMirror 中断时
