SMARTmail

This is a simple script that will collect results of SMART health checks (using smartctl) and send them as (formatted) emails to a given address (with just mail).

Guide

1. Download the scripts (mail.sh and format.py) to a directory of your choice. In my case it's /opt/smartmail - remember that path. Make sure to chmod execution privileges to mail.sh.
2. Configure the main script: set HERE variable to the aforementioned path (necessary in step 4), set MAIL to the address you wish to receive the reports on.
3. Select devices which you want to query: create a file disks.txt (obviously, in the same directory) and list devices in it, line by line. Do not use complete drive paths (i.e. don't include "/dev/")! State only the names of devices (e.g. ada0), one entry per line.
   (At this point you may want to test the script.)
4. Log in to your FreeNAS web interface and add a cron job with this script (Tasks -> Cron Jobs). Mine runs every 1st day of the month, after the long SMART self-test.

Voila, enjoy regular updates on the health status of your HDDs!
