适用场景

  • ONTAP 9
  • 存储效率
  • FlexGroup
  • FlexVol

问题解答

  • 否,由于 ONTAP 升级过程仅涉及根卷,因此无需进行此操作。
  • 即使已进行重复数据删除的卷和聚合没有足够的可用空间,也不会影响 ONTAP 更新,但更新效率可能会受到影响。

注:

  • 为确保重复数据删除功能正常运行,用户需要确认卷和聚合中是否存在足够的可用空间来存储重复数据删除元数据。重复数据删除元数据要求聚合中的可用空间量最低。
  • 此空间量相当于聚合中所有已进行重复数据删除的 FlexVol 卷或 FlexGroup 数据组成部分的总物理数据量的 3%。每个 FlexVol 卷或数据组成部分应具有总物理数据量的 4% 的可用空间,总计为 7%。
