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
