中古 HDD の初期確認、5個目(2017年4月)

これまで4個の中古 HDD を購入しましたが、先日、2個目 (2015年10月購入) が壊れてしまったため、交換用に5個目を購入しました。

いつもの初期確認、まずは S.M.A.R.T. の値です。

なんと、稼働時間は 635 時間 (約26日) でした。ただ、HDD のラベルに書いてある Date Code: が 09421 で、製造年月は2009年4月ということになります。8年間、ほとんど眠っていたわけです。

4台で RAIDZ 構成を組んでまして、このあと zpool replace で、無事に故障ディスクを置き換えて、冗長性回復できました。この状態で2年ぐらい安定してくれるといいな。
