View source for HOWTO Setup S.M.A.R.T. hard-drive Monitoring

Typically, we use a 3Ware controller, with anywhere from 2 - 16 individual hard-drives attached.  Although we use 3Ware's '''tw_cli''' tool in both a daily cron-job and also in a Nagios monitor, it's also a good idea to get a daily logwatch-email stanza with drive-statistics and alerts.  Belts and suspenders, you know.

In addition to (passive) monitoring, we actively invoke Long Self-Tests on each drive.  These tests are scheduled to try to hit low-usage times, and also avoid our tape-backup times.

Install the (Gentoo) package:
 <font color=red>hostname</font> <font color=blue># </font>'''emerge -av smartmontools'''

Start the '''smartd''' monitoring daemon automatically in the default runlevel:
 <font color=red>hostname</font> <font color=blue># </font>'''rc-update add smartd default'''

Representative configuration file:
 <font color=red>hostname</font> <font color=blue># </font>'''emacs -nw /etc/smartd.conf'''
