Linux command – smartd

指令 #smartctl – https://benjr.tw/95984 是透過硬碟本身所提供的 S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology )技術 ,他可以根據檢測屬性的結果來決定該顆硬碟的使用是否快故障.但手動的總是不方便,我們可以使用 smartd (Daemon) 自動執行.

測試環境為 Ubuntu14.04

啟用 smartd, 並設定檢查間隔時間為 interval=1800 秒

root@ubuntu:~# nano /etc/default/smartmontools
start_smartd=yes
smartd_opts="--interval=1800"

剛剛設定 smartd 服務是否啟動與間隔時間,詳細的測試項目須參考這一檔案.

root@ubuntu:~# nano /etc/smartd.conf
DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner

參數說明如下:

• -d TYPE
  1. ata – the device type is ATA.
  2. scsi – the device type is SCSI.
  3. 3ware,N – the device consists of one or more ATA disks connected to a 3ware RAID controller.
  4. removable – the device or its media is removable. This indicates to smartd that it should continue
• -n POWERMODE
  1. never – smartd will poll (check) the device regardless of its power mode.
  2. sleep – check the device unless it is in SLEEP mode.
  3. standby – check the device unless it is in SLEEP or STANDBY mode.
  4. idle – check the device unless it is in SLEEP, STANDBY or IDLE mode.
• -m : specifies an email address to send test reports to.
• -M : specifies the desired type of delivery for an email report.
  1. once: sends only one warning email for each type of disk problem detected.
  2. daily: sends additional warning reminder emails, once per day, for each type of disk problem detected.
  3. diminishing: sends additional warning reminder emails, after a one-day interval, then a two-day interval, then a four-day interval, and so on for each type of disk problem detected.
  4. test: sends a single test email immediately upon smartd startup.
  5. exec PATH: runs the executable PATH instead of the default mail command.
