适用于

  • ONTAP 9
  • FlexGroup
  • 卷移动
  • FlexClone

问题

  • Network 列中观察到高延迟 qos statistics volume latency show,这表明 ONTAP 网络处理中存在延迟
  • 未从已执行 vol-move 的成员卷中观察到高延迟,而应在同一节点上的其他成员卷中观察到高延迟。  
  • 高延迟在 vol-move 完成后立即开始
  • 仅 FlexGroup 作为 FlexClone 父项是不够的。所需条件如下:
    • FlexGroup FlexClone 父级
    • 父级在该节点上具有 >= 2 个成分
    • 克隆成分也在该节点上,并且尚未拆分。如果克隆成分被拆分或移动到另一个节点,则不会发生此问题。如果有多个克隆,则适用于所有克隆。
