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.
If you receive an email indicating problems, then you should manually run tests & view the report & take appropriate action (eg replace drive if necessary).
To manually check disks
Generate report
smartctl -t short /dev/sda (1 minute) smartctl -t long /dev/sda (1 hour) smartctl -t conveyance /dev/sda (5 minutes)
View report
smartctl -a /dev/sda
For additional information see:
