Smartmontools is a free software package, available for multiple platforms, that can utilizes the S.M.A.R.T. attributes of a hard drive to enquire about its state. With smartmontools, a how to check failed disk in linux tech-savvy admin/user will be adequately warned and prepared for a hard drive failure and can make backups before the drive becomes critical.InstallationOn Debian or Ubuntu systems, smartmontools is available via the default repositories.sudo apt-get install smartmontoolsOn Fedora:sudo yum install smartmontoolsInstalling smartmontools package delivers two programs to your system: smartctl, which should be used interactively, and smartd, which, as the name suggests, is a daemon program designed to run in the background.SmartctlSmartctl requires root permissions

to run and so must be run by the root user or a user with sudo privileges. Smartctl monitors an entire hard drive (not partitions), hence when run, it should be given the required hard drive as the final argument. For this article, we use "/dev/sda" as the hard drive device file. Be sure to replace that with your hard drive's file.To get information about a drive, use the -i option.sudo smartctl -i /dev/sdaThe above image shows some information about the drive, and we can see, from the highlighted lines, that SMART support is both available and enabled for the drive. Excellent. However, if SMART support is available but not enabled, it can be turned on with the following command:sudo smartctl -s on /dev/sdaTo check the device's health, use the -H option:sudo smartctl -H /dev/sdaIf the output for the above isn't PASSED, the hard drive has either failed or it is predicting its impending doom. Backup your data immediately.To view the SMART capabilities of the drive, use the -c switch:sudo smartctl -c /dev/sdaFrom the above screenshot, the drive supports self-tests, and the time for short and extended self tests are estimated at 2 minutes and 95 minutes respectively. To run the short test, use the -t short switch, and correspondingly, the -t long option for the extended (and more thoroug

In today's article, we will show you https://www.maketecheasier.com/monitor-hard-disk-health-linux/ some Linux disk utilities to diagnose the health of your hard disk. Image by Scoobay S.M.A.R.T System Most modern ATA and SCSI hard disks have a Self-Monitoring, Analysis, and Reporting Technology (SMART) system. SMART hard disks internally monitor their own health and performance. The SMART tool assesses the condition of your hard disk based on: the throughput of the hard disk, the http://www.howtogeek.com/howto/37659/the-beginners-guide-to-linux-disk-utilities/ seek errors rate of the magnetic heads, and other attributes that your hard disk manufacturer built into their hard disk. Most implementations of SMART systems allow users to perform self-tests to monitor the performance and reliability of their hard disks. The simplest way to perform a SMART system test with Ubuntu is using the ‘Disk Utility' under the ‘System' > ‘Administration' menu. The disk utility lets you see the model, serial number, firmware, and the overall health assessment of the hard disk, as well as whether a SMART system is enabled on the hard disk. The ‘SMART data' button lets you see the SMART features of your hard disk. The ‘Run Self-test' button lets you initiate a short,extended, or a conveyance self-test on the hard disk. When you execute these tests, you'll see a progress meter, letting you see how far through the test is and what the estimated time of completion is. The ‘Attributed section' lets you see the errors and self-test information. File System Check There some other tools, beside the Disk Utility GUI, that we can use to diagnos

How can I test if my hard disk is http://serverfault.com/questions/150471/check-for-hard-disk-errors-signs-of-failure-on-centos-server going bad? I see few errors in /var/log/messages file.I/O errors in /var/log/messages indicates that something is wrong with the hard disk and it may be failing. You can check hard disk for errors using smartctl command, which is control and monitor utility for SMART disks under Linux / hard drive UNIX like operating systems. smartctl controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into many ATA-3 and later ATA, IDE and SCSI-3 hard drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive failures, and to carry out different types of drive self-tests.smartctl for serverssmartctl is a command line utility designed linux hard drive to perform SMART tasks such as printing the SMART self-test and error logs, enabling and disabling SMART automatic testing, and initiating device self-tests. First, make sure S.M.A.R.T. support is enabled in the BIOS. Next, run the following command to see if your hard disks support S.M.A.R.T technology or not: # smartctl -i /dev/sdb To enable SMART, run: # smartctl -s on -d ata /dev/sdb Sample outputs:smartctl version 5.33 [x86_64-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF ENABLE/DISABLE COMMANDS SECTION === SMART Enabled.Run overall-health self-assessment test, enter: # smartctl -d ata -H /dev/sdb Sample outputs:smartctl version 5.33 [x86_64-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSEDA sample output from failing hard disk:smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED Please note the following marginal Attributes: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 190 Airflow_Temperature_Cel 0x0022 044Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Server Fault Questions Tags Users Badges Unanswered Ask Question _ Server Fault is a question and answer site for system and network administrators.

I'd also recommend running BadBlocks. If you've got a RAID card, you might have to use the monitoring on that. share|improve this answer answered Jun 11 '10 at 15:26 Dentrasi 3,0921718 add a comme
