问题描述

磁盘出现故障后、即使池0具有备用磁盘、磁盘重建也不会启动：

Fri Aug 19 06:06:27 JST [Nodename-01: config_thread: callhome.fdsk.fault:error]: Call home for FILESYSTEM DISK FAILED Shelf 1, Bay 9, Model [X341_TA14E900A10], S/N [XXXXXXXXXXXX] Fri Aug 19 06:06:27 JST [Nodename-01: config_thread: raid.rg.recons.missing:notice]: RAID group /aggr01/plex4/rg0 is missing 1 disk(s).

Pool1 spare disks (empty)

Pool0 spare disks

配置同步镜像后、目标磁盘位于aggr01的Plex4中、Plex4从池0生成：
