舊平成廿年戊子葉月廿玖日辛未 (日・曇):smartmontoolsでHDDの状態を監視する。 // コピー・プログラミングは無くならない。

2008-09-28 舊平成廿年戊子葉月廿玖日辛未 (日・曇) [昔の今日]

smartmontoolsでHDDの状態を監視する。

本當なら夏が始まる前に行つておけば良かつたのだが、今更乍らにKURO-BOX/PROでS.M.A.R.T.でHDDの監視を行ふ事にした。參考にしたのは以下の頁。

Debianではaptitudeで簡單に入つた。

# /usr/bin/aptitude install smartmontools
Reading package lists... Done
Building dependency tree
Reading state information... Done
(中略)
Not starting S.M.A.R.T. daemon smartd, disabled via /etc/default/smartmontools (warning).
(後略)

取敢へずHDDの情報を取得してみた。

# /usr/sbin/smartctl -a /dev/sda

其れから/etc/default/smartmontoolsを編輯してデーモンを起動した。

# /etc/init.d/smartmontools start

色々解説を讀んでみて取敢へず以下の樣に設定してデーモンを再起動した。

/etc/smartd.confはDEVICESANを無効にして/dev/sda用の設定を追加した。後root宛の電子郵便は携帶に送信する樣にPostfixを設定した。
