Linuxマシンのハードディスクの温度を測る
Linuxマシンのハードディスクの温度を測る

- 2006.06.22 新規作成
- 2006.06.23 SMARTがoffになっているときの確認
１．はじめに
このドキュメントでは，ハードディスクの温度を調べて，ログを記録する手順を説明する． 最近のハードディスクには，S.M.A.R.T.という規格でハードディスクのステータスがわかる機能があるが，その中から温度情報を取得し，定期的にログファイルに書き出す仕組みについて説明する．
２．smartctlコマンドを使ってHDDの状態を調べる
[root@artemis shinnai]# locate smartctl
/usr/share/man/man8/smartctl.8.gz
/usr/sbin/smartctl
[root@artemis shinnai]#
|
[root@artemis shinnai]# df -h

/dev/hda6 18G 5.5G 12G 33% /

- デバイス名が，/dev/hdaということがわかる．
- -aオプションを使って，すべての情報を
[root@artemis shinnai]# /usr/sbin/smartctl -a /dev/hda
