# Monitor SMART status, ATA Error Log, Self-test log, and track

-----------------

start service smartd on CentOS
systemctl enable smartd.service
systemctl start smartd.service
systemctl reload smartd.service
systemctl status smartd.service
check status is running
systemctl |grep smartd.service

ทำ Crontab เพื่อให้ smartd ค่อย monitor hard disk
# vim systemctlreload.sh
systemctl reload smartd
# chmod u+x systemctlreload.sh
# vim /etc/crontab
05 05 * * * root /root/systemctlreload.sh

ปรับแต่งการส่งเมลโดยให้ส่งเมลจาก Sender ที่เราต้องการ และปรับแต่ง Subject
vim /etc/smartmontools/smartd_warning.sh
----------------------------------------------------
# Format subject
export SMARTD_SUBJECT="ALERT: SMART error (${SMARTD_FAILTYPE-[SMARTD_FAILTYPE]}) detected on host: $hostname"

# Send mail, use platform mailer by default
  test -n "$SMARTD_MAILER" || SMARTD_MAILER=$os_mailer
  if [ -n "$dryrun" ]; then
    echo "exec '$SMARTD_MAILER' -s '$SMARTD_SUBJECT' -r "noreply@domain.com" $SMARTD_ADDRESS <$fullmessage
EOF"
  else
    exec "$SMARTD_MAILER" -s "$SMARTD_SUBJECT" -r "noreply@domain.com" $SMARTD_ADDRESS <$fullmessage
EOF
  fi
-----------------------------------------------------

หลังปรับ /etc/smartmontools/smartd_warning.sh ทดสอบสคริปด้วยคำสั่ง systemctl reload smartd.service แล้วรันคำสั่ง tail -f /var/log/maillog ดูว่าส่งเมลด้วย Sender ที่เราระบุไหม

vim /etc/smartmontools/smartd.conf
