适用场景

ONTAP 9
同一聚合中具有已分区和未分区驱动器的RAID组。

问题描述

配对节点处于备用磁盘不足状态：
- 配对节点：
  
  RAID group /aggr1_n1/plex0/rg1 (normal, block checksums)

- 本地节点有一个完整的可用备用磁盘：
  
  Pool0 spare disks

虽然本地上需要一个未分区的备用磁盘、但本地磁盘会自动分区：
- 配对节点：

具有未分区磁盘的聚合或RAID组在本地没有可用的备用驱动器、因此本地备用磁盘不足：

[LocalNode: config_thread: raid.rg.spares.low:error]: /aggr1_n2/plex0/rg2
