{{MessageBox|backgroundcolor = #faa|image =Warning.png|heading =WARNING|message = This is recommended only for advanced users, proceed with caution.}}Finding out a disk is bad after it crashes can often prove disastrous. To be warned of a failing disk is something we all would appreciate. This can be done via [http://smartmontools.sourceforge.net/ smartmontools]], a free software package that can monitor S.M.A.R.T. attributes and run hard drive self-tests. Basically, S.M.A.R.T. may give you enough of a warning that you can safely backup all your data before your hard drive dies. Obviously, nothing replaces regular backups, but it's absolutely better than knowing nothing!
First, Sendmail is off by default with Amahi installed. You will need to enable it, so do the following as '''root''' user('''NOTE:''' Skip if using Postfix):{{Code| service sendmail start chkconfig sendmail on}}
If you prefer to have alerts sent to an email address outside your HDA, try one of the following tutorials:
* [[Enable_Outgoing_Emails|Enable Outgoing Emails]]
This may already be installed in your system. If not, as '''root''' user do:
smartmontools comes with two programs; smartctl which is meant for interactive use and smartd which continuously monitors S.M.A.R.T.
You can do a quick test to see if it recognizes your drives (replace /dev/sda by the drive(s) present on your system):
To setup smartd to monitor your system automatically, edit the file ''/etc/smartd.conf'' (alternate location is ''/etc/smartmontools/smartd.conf''' ) and check for a line that begins with ''DEVICESCAN''. Comment it out by adding a ‘#’ to the beginning of the line something like this:{{Text|Text= #DEVICESCAN -H -m root -n standby,10,q}}
Add the following line to /etc/smartd.conf:
This an example from the config file:
Start the daemon with:
To restart after a rebootenable start on boot:{{Code| chkconfig smartd on}}
You can read local mail sent to root using [http://www.amahi.org/apps/webmin Webmin].
'''NOTE:''' You will receive a test email each day or so, one for each drive you identify to be monitored.
