中古 HDD の初期確認、3個目(2016年6月)

中古 HDD の初期確認。前回に続き、某ショップより3個目を入手しましたので、今回も備忘録です。

今回入手した中古 HDD も、前回と同じく Seagate Barracuda ES.2 1TB です。前回入手したものは S.M.A.R.T. エラーがある状態とのことで、かなり安い値段でしたが、今回の個体は、前回の値段+600円程度で入手できました。

まず、S.M.A.R.T. の確認です。

188 Command_Timeout がとんでもなく大きな値ですが、5 Reallocated_Sector_Ct が、1個目と2個目の半分ぐらいの値です。前回までの経験値からすると、十分に使えそうな感触です。

このあと、4台構成の RAIDZ に組み込みましたが、resilver と scrub でエラーが出ませんでしたので、十分に使えそうな感触です。


2018-10-23追記
とうとう限界に達したようなので、6個目の中古HDD を購入して、zpool replace しました。まだ、OSから認識できていますので、廃棄する前に smartctl のデータを採取しました。

SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 4 occurred at disk power-on lifetime: 38827 hours (1617 days + 19 hours)

このように、Reallocated_Sector_Ct が、しきい値 (THRESH) を下回り、FAILING_NOW という状態になりました。また、smartctl -t short や long を行っても、unknown failure になりました。貴重なデータと思います。
cron で週1回 smartctl -A のデータを収集していましたので、Reallocated_Sector_Ct の推移も貼っておきます。
