HDD「ンッーカッチャコンカッチャコンカッチャコン ンッーカッチャコンカッチャコンカッチャコン」

ファイルサーバから表題のような、いやーな音が聞こえてきた。

恐る恐るzpool statusをしてみると…

凄く・・・ご臨終です・・・・。

8/19ってことは、実家帰省のさなか延々カッコンカッコンしてたのか…。RAID-Z1なのでガクブルもの。てか、ホットスペアを自動で使ってくれないのね。何でだろう?

取りあえず、手動でお亡くなりになったHDDとスペアを置き換える。

まず、死んだHDDをプールから切り離す。

replaceコマンドの応答がなかなか(十数秒)返ってこず、少し焦ったw 3TBのHDD買ってこないとだな…。

それにしても、自分はSeagateとの相性がすこぶるよろしくない。HDDは去年の6/20に買ったものなので、1年ちょいでお亡くなりという事に。昔使ってた鯖でも、Seagate製が1年足らずで死んだんだよなぁ。RMAで動作品に交換出来ると思うが、さっさと売って新HDD費用の足しにしよう……。

(2014/8/25 1:18追記)

10TBのプールを10時間ほどでリビルド完了。

死んだHDDを切り離す。

ada0がケース内のどのHDDなのか特定するには、HDDの型番とシリアル番号が分かればいいので、通常はcamcontrol identify ada0すればOK。 ただし今回はada0の情報が全く表示されなかったため、生きている同型のHDDを1つずつidentifyし、死んだ玉を消去法で探し当てた。
