在TrueNAS/FreeBSD上定位故障硬盘槽位

刚做好一个NAS，利用TrueNAS做的，结果一直报da5有故障

Aug 21 23:51:30 truenas 1 2021-08-21T23:51:30.506395-07:00 truenas.local smartd 1421 - - Device: /dev/da5 [SAT], 624 Currently unreadable (pending) sectors

这里分享一下查找故障硬盘的方法。

1、对SN

如果NAS可以关机，那么可以通过SN，来一块一块硬盘对应。这是最有效的方法，也是最安全的方法。在web页面的硬盘里，找到故障硬盘的SN

2、通过工具去确认槽位.

TrueNAS集成了绝大部分的磁盘控制器管理软件

如：sas2ircu、sas3ircu、hptraidconf、storcli。

因为我这里用的是SAS2008的直通卡，所以使用sas2ircu。

1、查看磁盘控制器列表

2、查看磁盘控制器的硬盘

太长了，用grep吧

通过上述输出可以看到硬盘SN：Z1ZBG0SR对应的槽位是
Enclosure # : 1，Slot # : 7

那么可以先将此硬盘下线，在背板拔除此硬盘即可。
