天上天下唯我独尊!!ブログのFreeBSDと自作PCのまとめ記事です.

CPUをQuad Core Q9650へ換装し、暫く様子を見ていました。
しかし、先週4機搭載しているうちの1つ、Seagate製のSATA 250GBのHDDが突然マウント出来なくなり、DMAエラーを出すようになりました。
DMAのモードをいろいろ変更しましたが、どうもタイミングの問題なのか、マウント出来る時と出来ない時があることが
分かりました。いろいろ試行錯誤しながら復旧を試みようとしましたが、この段階ではダメでした。


そんな状況でタイミング良く秋葉原のクレバリーからタイムセールのお知らせメールが来ました。メールを読むと2TBのWestern Digital製
のHDDが9350円!思わずポチしてしまいました。


先週の土曜日に2TBのHDDが到着したので、早速、Seagate製の250GBのHDDと入れ替えを行い、250GBのHDDをリムーバブルケースへ入れて起動。
増設したWestern Digital製2TBのハードディスクを認識させるため、/usr/sbin/sysinstall→Configure→FDISK→LABELでそれぞれ設定し、無事認識。
一方の250GBのHDDはと言うと、何事も無かったかのようにちゃんと認識しマウント出来ました。
何が悪かったのでしょうか?

250GBの方はSATAのコネクタをリムーバブルケースに接続を変えただけのことなんですが、一体何があったのでしょうね。
と、言うわけで250GBのHDD内に入っているデータをrsyncを使って2TBのHDDにコピーしました。
これにて一件落着。と、言いたいところですが原因不明というのがどうも気になります。



そこで、もう少し詳しく調査してみました。
まずは、お決まりのdmesg。

そして次に更にHDDの状況を詳しく知るためにsmartmontoolsを導入します。
smartmontoolsによりHDDの障害切分けを行います。

インストール自体は簡単です。
/usr/ports/sysutils/smartmontools よりインストールします。

設定はこちらのサイトが分かりやすいです。

で、smartctl -a /dev/ad18 > /home/20120519_smartmontools_ad18

SMART Error Log Version: 1
ATA Error Count: 12 (device log contains only the most recent five errors)
	CR = Command Register [HEX]

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 12 occurred at disk power-on lifetime: 16289 hours (678 days + 17 hours)
  When the command that caused the error occurred, the device was active or idle.

これを見てもやはりDMAによるエラーが出ています。その理由はデバイスがアクティブではなくアイドル状態になっていた為ということなんですが・・・。
もう少し時間を掛けて調査する必要があるようです。
