Use Smartmontools tool to detect Linux hard disk status – installation and basic application

Smartmontools is an open source disk detection and control tool. I happened to come into contact with a server today and wanted to check the power-on time of the hard disk of this server. This tool was used, so I recorded the installation and simple application of this tool. Come on, after all, my brain doesn’t work very well as I get older. Users who have a little trouble will find it useful when selecting a server to check the hard disk health status and related parameters.

First, Smartmontools installation

1. CentOS

yum install smartmontools -y

2. Debian

apt-get install smartmontools -y

Select the corresponding system to perform script installation. According to the introduction, there is also a WIN version, but WIN is generally less commonly used, because there are still many detection software for WIN systems. Snail has basically never used a WIN server, so I won't look for it.

Second, simple application of Smartmontools

1. List the hard drives connected to the system

2. Display information about a specific hard drive

3. Check the hard disk health status

smartctl -s on -a /dev/sda

The return result is PASSED which means normal.

4. Check the hard drive power-on time

smartctl -A /dev/sda

To summarize, the above is the basic application of Smartmontools hard disk detection tool. Snail (laozuo.org) will record so much here and update it later if it is useful.
