适用场景

Element 软件

  • 所有版本  

ESX

  • ESXi 5.5
  • ESXi 6.0
  • ESXi 6.5

VMFS

  • VMFS 5.
  • (使用 VMFS 6 的 ESXi 6.5 会自动运行此命令,无法取消映射) 

(可选)适用于 vCenter 的 Element 插件( VCP )

  • VCP 4.3
  • VCP 4.2.3
  • VCP 4.1
  • VCP 4.0

问题描述

取消映射是一种 ESXi 基元,它允许 ESXi 主机通知存储阵列已从精简配置的 VMFS 数据存储库中移动或删除文件或 VM 。  这样, Element 就可以正确释放未使用的块空间并回收容量。   

如果 vCenter 报告的已用数据少于 Element 使用的数据,则取消映射非常有用。
