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 setprop smartd status enabled

And start, (smartd will start automatically on a reboot if enabled)

/etc/rc.d/init.d/smartd start

Errors are emailed admin if and when they are found.

To manually check disks

Generate report

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

View report

smartctl -a /dev/hdc
