smartctl

虚拟机不支持这个工具我主要是用它的查看健康状态这个功能，其它的用的少，算是mark以后用的时候再看吧

(1)检测是否开启

/dev/sda2是设备名，可以写需要检测的设备名称，N是终端编号，我在不加-d megaraid,0的时候终端提示如下

[root@rsync ~]# smartctl -i -d megaraid,0 /dev/sda2 | grep Device
Device type:          disk
Device supports SMART and is Disabled            //查看之后支持但是是关闭状态

(2)开启smart

[root@rsync ~]# smartctl --smart=on --offlineauto=on --saveauto=on -d megaraid,0 /dev/sda2

检测是否开启

[root@rsync ~]# smartctl -i -d megaraid,0 /dev/sda2|grep Device
Device type:          disk
Device supports SMART and is Enabled             //已经是enabled状态

(3)查看健康状态

[root@rsync ~]# smartctl -H -d megaraid,0 /dev/sda2 | grep SMART
SMART Health Status: OK

(4)显示设备厂商和属性

[root@rsync ~]# smartctl -A -d megaraid,0 /dev/sda2

(6)硬盘自测

这个工具我自己装了几遍都有问题，执行以后得到的信息很少，我以为是自己装的有问题，但是反复检查没什么毛病，然后直接去的官网看的，才发现linux版本确实存在这个问题，很多系统或者服务器都不支持。但是windows版本还是可以的。作者在回复网友说是会继续开发linux版本，有最新版本会在官网上发布的，敬请期待。
