Linux small knowledge of hard disk health status detection

Smartctl

The virtual machine does not support this tool I mainly use it to view the health of this function, the other use of less, as mark after the use of the time to see it

(1) detection is turned on

/dev/sda2 is a device name, you can write the device name to be detected, n is the terminal number, I do not add-D megaraid,0 when the terminal prompt as follows

[Email protected] ~]# smartctl-i-D megaraid,0/dev/sda2 | grep device device Type:diskdevice supports SMART and is Disabled//view supported but off state

(2) Turn on smart

[Email protected] ~]# smartctl--smart=on--offlineauto=on--saveauto=on-d megaraid,0/dev/sda2

Detect if Open

[Email protected] ~]# Smartctl-i-D megaraid,0/dev/sda2|grep devicedevice Type:diskdevice supports SMART and is enabled//already enabled state

(3) View health status

[Email protected] ~]# smartctl-h-D megaraid,0/dev/sda2 | grep Smartsmart Health Status:ok

(4) Display device manufacturers and properties

Hdsentinel

This tool I installed a few times have problems, after the implementation of the information is very few, I think it is the problem of their own outfit, but repeatedly check nothing wrong, and then go directly to the official website to see, only to find that the Linux version does exist this problem, many systems or servers are not supported. But the version of Windows is still available. The author in reply to the Netizen said will continue to develop the Linux version, the latest version will be published on the official website, please look forward to.
