1 - Summary
This guide will show how to install smartmontools in Mythbuntu. Smartmontools
can run tests to monitor the SMART of hard disks. This has been tested in
Mythbuntu 12.04.
2 - Dependencies
Install the apt-file package.
# sudo apt-get install apt-file
[sudo] password for user:
Install the msmtp package. Msmtp is an SMTP client used to send email. We will
use it to send email notifications.
# sudo apt-get install msmtp
[sudo] password for user:
It's helpful to know what type of hard disks the computer has. You can find
this out by typing the following.
# sudo parted -l | grep Disk
[sudo] password for user:
Disk /dev/sda: 4000GB
Disk /dev/sdb: 2000GB
In this case there are two hard drives which are RAID arrays. Get more
information about the RAID arrays by typing the following.
# dmesg | grep -e '\[sda]\|\[sdb]' | uniq

The sda and sdb disks are on a 3ware 9500S-8 controller card which is a SATA
RAID card meaning that there are multiple hard disks connected to it in a RAID
configuration.
# dmesg | grep -i 3ware | uniq
[ 3.002563] 3ware 9000 Storage Controller device driver for Linux v2.26.02.014.

The tw_cli software from 3ware has to be installed in order to get information
about the hard disks. Add the following software repository.
# 3Ware
deb http://jonas.genannt.name/debian lenny restricted
# sudo vi /etc/apt/sources.list
[sudo] password for user:
# su - root
Password:
# wget -O - http://jonas.genannt.name/debian/jonas_genannt.pub | apt-key add -
# logout
# sudo apt-get update
[sudo] password for user:
# apt-cache search 3ware
3ware-3dm2-binary - 3ware 3DM 2 Disk Management Utility
3ware-cli-binary - Command Line Interface for 3Ware Controllers
# sudo apt-get install 3ware-cli-binary
[sudo] password for user:
Get more information about the hard disks attached to the 3ware controller by
typing the following. Since the hard disks are identical we will get the model
number of just one of them.
# sudo tw_cli
[sudo] password for user:

Now, with the model of the hard drives find out if they are ATA, SCSI or SAT.
Since some hard disks are attached to a 3ware SATA RAID controller, there is
also software from 3ware to view information via a website interface. Install
the 3dm2 package.
# apt-cache search 3ware
3ware-3dm2-binary - 3ware 3DM 2 Disk Management Utility
3ware-cli-binary - Command Line Interface for 3Ware Controllers
# sudo apt-get install 3ware-3dm2-binary
[sudo] password for user:
Enable the 3dm2 service so that it will start when the system starts up.
# sudo update-rc.d 3dm2 enable
[sudo] password for user:
The 3dm2 service has already been started as part of the installation process.
# pgrep 3dm2
6372
6373
6374
Modify the configuration file for 3dm2. The default password for the
Administrator user is 3ware.
RemoteAccess 1
# sudo cp /etc/3dm2/3dm2.conf /etc/3dm2/3dm2.conf.example
[sudo] password for user:
# sudo vi /etc/3dm2/3dm2.conf
[sudo] password for user:
# sudo service 3dm2 restart
[sudo] password for user:
3 - Smartmontools installation
Install the smartmontools package.
# sudo apt-get install smartmontools
[sudo] password for user:
4 - Service configuration
Find where the smartmontools daemon was installed to.
# apt-file update
# apt-file list smartmontools | awk '{print $2}' | grep sbin
/usr/sbin/smartctl
/usr/sbin/smartd
/usr/sbin/update-smart-drivedb
Edit the default options file to have the following.
smartd_opts="-p /var/run/smartd.pid -q never"
# sudo vi /etc/default/smartmontools
[sudo] password for user:
Enable the smartmontools service so that it will start when the system
starts up.
start_smartd=yes
# sudo vi /etc/default/smartmontools
[sudo] password for user:
Find where the configuration file should be put.
# grep smartd.conf /etc/init.d/smartd
config=/etc/smartd.conf
echo -n "Reloading smartd configuration: "
SMARTD_CONFIG=/etc/smartd.conf
echo -n "Reloading smartd configuration: "
# strings /usr/sbin/smartd | grep smartd.conf
/etc/smartd.conf
You can create your own configuration file. Here is a simple example. This
will disable Autosave and will schedule a short self-test between 8-9 PM every
night and send warnings or errors to the email address provided. Scheduled
tests are run after the default scheduled device polling, which by default
is every thirty minutes after the smartd service is started.

Reboot your computer. Log in like normal and check to see that the
smartmontools service is running. That's it, now you have smartmontools
running in Mythbuntu.
