smartmontools monitor storage device's health status-阿里云开发者社区

不管是SSD硬盘还是机械硬盘, 都有使用寿命.

大多数的硬盘是支持S.M.A.R.T的, 全称( Self-Monitoring, Analysis and Reporting Technology)

smartmontools这个工具可以用来读取硬盘的smart信息, 进行测试, 改变一些属性等.

操作系统自带的smartmontools版本较低, 所以建议去源站下载一个最新的, 可以支持更多的硬盘.

使用smartmontools可以提前知道哪些硬盘可能要坏了, 做好预先更换的准备. 像EMC的CX4存储就带这个功能, 能够提前侦测出硬盘是否可能会坏了, 提前用hot spare盘顶上去. 这样能提高卷组的可靠性, 减少数据丢失的风险, 在硬盘数量较多的卷组中尤为重要.

我们也能够利用smartmontools这个工具来提前对硬盘的使用情况进行告警.

安装 :

wget http://downloads.sourceforge.net/project/smartmontools/smartmontools/6.0/smartmontools-6.0.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fsmartmontools%2Ffiles%2Fsmartmontools%2F6.0%2F&ts=1354091701&use_mirror=jaist
tar -zxvf smartmontools-6.0.tar.gz
cd smartmontools-6.0
./configure --prefix=/opt/smartmontools-6.0
make
make install

使用 :

查询你的硬盘是否在对应的smartmontools版本库中 :

硬盘是接在RAID卡上的, 所以这里要加上设备, 后面有一个是PCI-E设备, 不需要加--device

以下是希捷的机械盘

SMART属性介绍 :

参见 : http://en.wikipedia.org/wiki/S.M.A.R.T.

这里有个表, 但不是每个硬盘厂商的都一样, 可能略有变化.

具体请看smartctl -A的输出.

例如 :

[root@db-172-16-3-150 smartmontools-6.0]# /opt/smartmontools-6.0/sbin/smartctl -A /dev/sdd
smartctl 6.0 2012-10-10 r3643 [x86_64-linux-2.6.18-274.el5] (local build)

以上是OCZ PCI-E RevoDrive3的输出, 所以要到OCZ厂商索取SMART的attribute信息表, 根据芯片不同, 也有不同的smart属性.

其他 :

smartd 可以用来调度硬盘检查计划.

配置文件的写法参考man smartd.conf
