smartd is a utility to check on the Self-Monitoring, Analysis and Reporting Technology or S.M.A.R.T. of a physical storage device like a hard drive or solid state drive.

1. Configure /usr/local/etc/smartd.conf

   DEFAULT -a -d scsi -m me@example.com -s S/../.././03
   /dev/da0
   /dev/da1
   /dev/da2
   /dev/da3
   /dev/da4
   /dev/da5
   DEFAULT -a -d scsi -m me@example.com -s S/../.././04
   /dev/da6
   /dev/da7
   /dev/da8
   /dev/da9
   DEFAULT -a -d scsi -m me@example.com -s S/../.././05
   /dev/da10
   /dev/da11
   /dev/da12
   /dev/da13
   DEFAULT -a -d scsi -m me@example.com -s S/../.././06
   /dev/da14
   /dev/da15
   /dev/da16
   /dev/da17
   DEFAULT -a -d scsi -m me@example.com -s S/../.././07
   /dev/da18
   /dev/da19
   /dev/da20
   /dev/da21
   

   The DEFAULT statements allow you to set default settings for the disks defined below. The porperties will remain the same until the next DEFAULT statement is defined.

   • The -a monitors all SMART properties.
   • -d identifies the device type (mine are all SATA).
   • -m denotes where you want failure emails sent.
   • -s sets a REGEX for how and when you want the test performed.
     • S is a short test. L is a long test.
     • The when statement is month/day-of-week/day/hour all represented in two-digit format.

2. Enable the service to start and start it

   sysrc smartd_enable=YES -f /etc/rc.conf.local
   service smartd start
   

That's it!
