・smartctl の出力についてまとめてみた - BitWalker
・Linux向けハードディスク監視/設定アプリケーションの紹介
最近暑くなってきてHDDの調子が気になったので調べてみた
あんまり参考にならない?なんて事も言われていますが
見ないより見た方がいいんじゃね?ってことで
インストール
# yum install smartmontools
まずS.M.A.R.T.に対応しているか調べましょう
(対応してないことなんて滅多にないと思うけど)
# smartctl -i /dev/sda

うちでは対応(Available)しているし、既に有効(Enabled)になってるみたいです
無効になってる場合は以下のコマンドで有効にできる
(ちなみにoffにすると無効になるけどなにかメリットはあるのかな?)
# smartctl -s on /dev/sda

で、とりあえず今結果を知りたいんだよって人は
# smartctl -H /dev/sda

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED
PASSEDなのでOKみたい、手動でテストを開始する場合には
(shortをlongにすると結構待たされるみたい、今回はとりあえずshortで)
# smartctl -t short /dev/sda

Testing has begun.
Please wait 1 minutes for test to complete.
Test will complete after Wed Jun 16 18:26:39 2010
Use smartctl -X to abort test.
1分待ってねって言われるので1分後に
# smartctl -l selftest /dev/sda

Completed without errorなので一応エラーは出てないみたいです
エラーログは以下のコマンドで見れます

Selective self-test flags (0x0):

If Selective self-test is pending on power-up, resume after 0 minute delay.
Pre-failがたくさん出てびっくりしたけどそういうものらしい
VALUEとWORSTがTHRESHを下回っていなければいいみたい
だけど1、5、196、197、198の項目は重要で
RAW_VALUEが0じゃない場合は結構やばいらしい
というわけで一応S.M.A.R.T.的には大丈夫って判断らしい
温度が39度ってのはもうちょっと冷やした方がいいのかなぁ
