How do I read my hard disk temperature using smartool (smartctl command) under FreeBSD operating system?
smartd is a daemon that monitors the Self-Monitoring, Analysis and Reporting Technology (SMART) system 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.
You need to use the smartctl command to Control and Monitor Utility for SMART Disks.
FreeBSD Install smartctl / smartd
Use FreeBSD ports system as follows:
# cd /usr/ports/sysutils/smartmontools
# make install clean
OR use binary package system:
# pkg install smartmontools
Make sure smartd start at boot time. Type the following command as root user:
echo 'smartd_enable="YES"' >> /etc/rc.conf
echo ‘smartd_enable="YES"’ >> /etc/rc.conf
Make sure your hard disk support SMART monitoring, enter:
# smartctl -i /dev/ad0
# smartctl -i /dev/ada1
