188.8.131.52. Monitoring drive health
Self-Monitoring, Analysis, and Reporting Technology (SMART) is built into most modern disk drives. It provides access to drive diagnostic and error information and failure prediction.
Fedora provides smartd for SMART disk monitoring. The configuration file /etc/ smartd.conf is configured by the Anaconda installer to monitor each drive present in the system and to report only imminent (within 24 hours) drive failure to the root email address:
/dev/hda -H -m root
/dev/hdb -H -m root
/dev/hdc -H -m root
(I've left out the many comment lines that are in this file.)
It is a good idea to change the email address to the same alias used for your RAID error reports:
/dev/hda -H -m raid-alert
/dev/hdb -H -m raid-alert
/dev/hdc -H -m raid-alert
If you add additional drives to the system, be sure to add additional entries to this file.
