适用于

  • ONTAP 9
  • FabricPool

问题描述

  • 聚合上所有卷的空间使用量与聚合的已用空间不匹配
  • 在节点上添加单个卷的已用空间时，其值远大于聚合上已用空间的总和
  • 示例：

以下使用数据是通过从 df-m 的输出中汇总所有卷的使用数据而获得的 

node1 - 1038520649 MB 或 1.0385 PB
node2 - 661991236 MB 或 661.9 TB
=====================================
总使用量 ~ 1.7PB（两个集群的所有卷合并）

而两个集群在聚合级别的总使用量如下所示
节点1 - 278 TB
节点2 - 130 TB
=====================================
总使用量 - 408 TB（来自两个集群的所有聚合组合）
