适用场景

问题描述

  • 两个运行ONTAP >= 9.12.1的不同集群报告的可用聚合大小不同。
  • 这两个聚合的配置完全相同(相同的RAID级别、相同的驱动器数量、相同的驱动器/分区大小等)
  • 聚合大小短于30 TB。
  • 差异约为5%:

cluster1::*> aggr show -fields size,diskcount  -root false
aggregate               diskcount size  
----------------------- --------- -------
aggr_data01             22      26.64TB

 

cluster2::> aggr show -fields size,diskcount  -root false
aggregate               diskcount size   
----------------------- --------- -------
aggr_data02        22        28.12TB

注意: 此示例来自MetroCluster、默认情况下、此WAFL会在隐藏的Snapshot预留之上预留5%的聚合Snapshot预留。

  • 聚合较小的集群已升级到>=9.12.1。
  • 新安装的集群中的聚合较大、安装位置>=9.12.1。
