linux查看硬盘温度和使用情况
硬盘用在服务器上好几年了,加上用的时候还是一个用了好几年的旧硬盘,担心它会不会突然挂掉。
用百度搜索linux下查看硬盘温度和使用时间的,发现如下工具:
2007、2008年我配过两台台式机,都用的三星160GB 硬盘,到2015年6月17日,就是现在,用在linux服务器上,还非常优秀。
检测温度:
sudo hddtemp /dev/sda
WARNING: Drive /dev/sda doesn't appear in the database of supported drives
WARNING: But using a common value, it reports something.
WARNING: Note that the temperature shown could be wrong.
WARNING: See --help, --debug and --drivebase options.
WARNING: And don't forget you can add your drive to hddtemp.db
/dev/sda: SAMSUNG HD161HJ 36°C or °F
而另一台机器,用的西数黑盘和希捷,都是160GB的,温度达到50摄氏度左右。
另外,三星硬盘噪音还是比较大一点,那会儿的160GB硬盘噪音都那么样,噶扎噶扎的响,用在linux上就温柔多了。
主要是品相,我担心硬盘用的时间太长了,怕坏了,上周六拆开用湿毛巾擦了擦,竟然很新,比购买的二手希捷和西数硬盘漂亮多了。应该拍照留念好了。看看我的硬盘在服务器工作了4年左右的使用时间:

4万多小时了。
这个工具是linux上自带的。
还有一个工具叫hddtemp,需要自己安装,百度搜索可以找到安装方法,centos下需要下载安装,ubuntu上则可以apt-get。其它linux请自行学习。
使用的时候需要root权限:
