ずいぶん前の出来事だけれど、 Hitachi Deskstar 7K1000.D がエラーを吐いて使えなくなったので
その時のS.M.A.R.T.の結果を記録しておく

こんなメールでRAIDのアレイから外したことを通知されました

This is an automatically generated mail message from mdadm

A Fail event had been detected on md device /dev/md1.

It could be related to component device /dev/sdc.

Faithfully yours, etc.

P.S. The /proc/mdstat file currently contains the following:

Personalities : [raid1]
md1 : active raid1 sdd[1] sdc[0](F)
      976762448 blocks super 1.0 [2/1] [_U]

md0 : active raid1 sdb[2] sda[0]
      2930266448 blocks super 1.0 [2/2] [UU]

unused devices: <none>

とりあえずRAIDは手元にあった古いディスクに差し替えて
問題のHDDのS.M.A.R.T.を確認してみたらこんな感じでした

OS側からエラーだからといって外されるのにS.M.A.R.T.では検出されないのね…
