适用场景

  • ONTAP 9
  • FlexGroup
  • 卷移动
  • FlexClone

问题描述

  • qos statistics volume latency showNetwork 列中观察到高延迟,表示ONTAP网络处理存在延迟
  • 卷移动后的成分卷不会出现高延迟、而是应在同一节点上的其他成分卷上出现高延迟。  
  • 高延迟会 在卷移动 完成后立即开始
  • 仅将FlexGroup作为FlexClone父级是不够的。所需条件如下:
    • FlexGroup FlexClone父级
    • 父节点在该节点上的成分卷大于或等于2个
    • 克隆成分卷也位于该节点上、并且尚未拆分。如果克隆成分卷/配置文件已拆分或移动到另一个节点、则不会出现此问题。如果存在多个克隆、则此操作会适用场景所有克隆。
