{{From|https://help.ubuntu.com/community/Smartmontools}} {{Languages|UbuntuHelp:Smartmontools}} This how to will help you to configure Smartmontools to do actions as shut down the computer or send an e-mail when the disk is going to fail. === Prerequisites === * A modern hard disk S.M.A.R.T. capable === Installation === First of all, we have to install Smartmontools package. Install the <code><nowiki>smartmontools</nowiki></code> package in the Synaptic Package Manager. See [[UbuntuHelp:SynapticHowto]]. To display all the SMART information for a disk, run <pre><nowiki> sudo smartctl -a /dev/hda </nowiki></pre> Now we have to edit some files. Open the file <code><nowiki>/etc/default/smartmontools</nowiki></code> with your favourite text editor, for example, vim: <code><nowiki>sudo vim /etc/default/smartmontools</nowiki></code> an uncomment the line <code><nowiki>start_smartd=yes</nowiki></code> Then, we are going to edit the daemon configuration. Again, use your favourite text editor to open the file <code><nowiki>/etc/smartd.conf</nowiki></code>. Comment out the line that contains <code><nowiki>DEVICESCAN</nowiki></code>, by adding # in the beginning of the line. Then, add this to the end of the file: <pre><nowiki>/dev/hda \ -H \ -l error -l selftest \ -s (O/../../5/11|L/../../5/13|C/../../5/15) \ -m ThisIsNotUsed -M exec /usr/local/bin/smartd.sh</nowiki></pre> You must replace <code><nowiki>/dev/hda</nowiki></code> with the name of the device which you'd like to be monitored. With this, the daemon will check the disk from time to time, and will execute <code><nowiki>/usr/local/bin/smartd.sh</nowiki></code> if any error is encountered. Now, we are going to make the script which is going to shut down the computer. Create a text file called <code><nowiki>smartd.sh</nowiki></code> in <code><nowiki>/usr/local/bin/</nowiki></code> (you could use the command <code><nowiki>sudo vim /usr/local/bin/smartd.sh</nowiki></code> to do so) and add the following to the file: <pre><nowiki>#!/bin/bash LOGFILE="/var/log/smartd.log" echo -e "$(date)\n$SMARTD_MESSAGE\n" >> "$LOGFILE" mail admin[at]alcalleop[dot]net < $LOGFILE sleep 40s shutdown -h now</nowiki></pre> This will send the log file by e-mail to admin[at]alcalleop[dot]net, wait 40 seconds and then will shut down the computer. You can customize the script to change what the computer will do in a case of disk error. For example, perhaps you do not want the computer to shut down. Now, it is time to start the daemon: <code><nowiki>sudo /etc/init.d/smartmontools start</nowiki></code> If you want to test all of this, add <code><nowiki>-M test</nowiki></code> after <code><nowiki>-M exec /usr/local/bin/smartd.sh</nowiki></code> and restart the daemon. This will force daemon to execute the script immediately. '''Now, every time the computer is turned on, the script will shut down the computer, so you will have to start the computer in recovery mode and remove <code><nowiki>-M test</nowiki></code> option of <code><nowiki>/etc/smartd.conf</nowiki></code> file.
