How to install Smartctl Utility On CentOS 7?

Posted by By Hostakers 3 Min Read

S.M.A.R.T. is a system in modern hard drives designed to report conditions that may indicate impending failure. smartmontools is a free software package that can monitor S.M.A.R.T. attributes and run hard drive self-tests. Although smartmontools runs on a number of platforms, I will only cover installing and configuring it on Linux.

Smartctl (Self-Monitoring, Analysis and Reporting Technology) is a command line utility or a tool in UNIX like operating system that perform SMART tasks such as printing the SMART self-test and error logs, enabling and disabling SMART automatic testing, and initiating device self-tests.

Installation of Smartcl.

# yum install smartmontools.

# systemctl start smartd ; systemctl enable smartd

Check Whether Smart Capability is enabled or not for the disk.

# smartctl -i /dev/sda

If above command fails, you may need to tell smartctl that what type of hard drive interface you are using:

# smartctl -a -d ata /dev/sdb // For SATA drive

Replace /dev/sda with your hard drive’s device file. The output of the command:

=== START OF INFORMATION SECTION ===  
Model Family:     SAMSUNG SpinPoint T133 series.
Device Model:     SAMSUNG HD300LJ  Serial Number:    S0D7J1UL303628.
Firmware Version: ZT100-12  User Capacity:    300,067,970,560 bytes.
Device is:        In smartctl database [for details use: -P show]
ATA Version is:   7  ATA 
Standard is:  ATA/ATAPI-7 T13 1532D revision 4a 
Local Time is:    Fri Jan  2 03:08:20 2009 EST.
SMART support is: Available - device has SMART capability.
SMART support is: Enabled

Enable Smart Capability for the disk

# smartctl -s on -o on -S on /dev/sda

Output of the command:

=== START OF ENABLE/DISABLE COMMANDS SECTION ===  
SMART Enabled.  
SMART Attribute Autosave Enabled.  
SMART Automatic Offline Testing Enabled every four hours.

Disable Smart Capability for the disk

# smartctl -s off /dev/sdb

Display Overall health of the Disk

# smartctl -H /dev/sdb

Output of the command:

=== START OF READ SMART DATA SECTION ===  
SMART overall-health self-assessment test result: PASSED

Let’s make sure that the drive supports self-tests.

# smartctl -c /dev/sda

Output of the command will be somewhat lengthy. Look for output similar to:

Short self-test routine 
recommended polling time:      (   2) minutes. 
Extended self-test routine 
recommended polling time:      ( 127) minutes.

Test Hard drive using long option.

# smartctl –test=long /dev/sdb

Test Hard drive using short option.

# smartctl –test=short /dev/sdb

You can run to check results.

# smartctl -l selftest /dev/sda

=== START OF READ SMART DATA SECTION === 
SMART Self-test log structure revision number 1 
Num  Test_Description Status Remaining  LifeTime(hours) 
LBA_of_first_error

Display Error logs of the disk

smartctl -l error /dev/sdb
