问题描述

借助高级磁盘分区( ADP )、物理磁盘在存储级别划分为少量分区、每个分区均被 RAID 和 HA 视为逻辑磁盘。聚合是从分区配置的、而不是从整个磁盘配置的。跨节点和聚合共享磁盘的能力有助于大大提高入门级配置(例如 12 个 HDD 和 24 个 HDD 的 NetApp FAS 系统以及全闪存 FAS (AFF) 系统上的存储效率。 

磁盘分区有两种类型:

数据分区方法有两种:

  • 根数据(RD): 将驱动器划分为一个根分区(P2)和一个数据分区(P1)
  • 根-数据-数据(RD2): 将驱动器划分为一个根分区(P3)和两个数据分区(P1、P2)

 

本文提供了多种识别分区的方法、包括系统中的备用磁盘。
