Monitor Disk Health

Self-Monitoring, Analysis and Reporting Technology (SMART) is built into many ATA-3 and later ATA, IDE and SCSI-3 hard drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive failures, and to carry out different types of drive self-tests.

To enable

config set smartd service 
config setprop smartd status enabled
ln -s /etc/rc.d/init.d/e-smith-service /etc/rc.d/rc7.d/S40smartd

This will log warnings to /var/log/messages.

to send warning to admin. append the -m admin directive to DEVICESCAN in the config file

nano -w /etc/smartd.conf  
DEVICESCAN -a -m admin -I 190 -I 194

To manually check disks

View report

smartctl -a /dev/hdc

Generate report

smartctl -t short /dev/hdc (1 minute)
smartctl -t long /dev/hdc (1 hour)
