Linux 查看硬盘通电时间

文章目录

今天买了台9刀的便宜(垃圾)独服,通上电,想看看硬盘用了多久。就顺手记录一下 Linux 下查看硬盘通电时间的操作吧,其实也比较简单。

查看硬盘通电时间

Ubuntu / Debian:

apt install smartmontools
smartctl -A /dev/sda

CentOS:

yum install smartmontools
smartctl -A /dev/sda

其中 /dev/sda 是硬盘编号,第一块一般是 /dev/sda,如果有多块硬盘,第二块就是 /dev/sdb,以此类推。

报告说明

一般我们会看到如下的输出:

root@185a140b120c93:~# smartctl -A /dev/sda
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.13.11-041311-generic] (local build)

其中的“9”,“Power_On_Hours_and_Msec”,就是硬盘通电时间,可以看到我这块硬盘已经通电 21343h+10m+10.810s,算下来有两年半了,真是垃圾。
