SMART RAID1のすべてのドライブで短いオフラインテストが終了することはありません
私はここで奇妙な状況にあります。低トラフィックサーバーで約3年後、RAID1の2つのSamsungドライブのうちの1つが昨日故障しました。
Personalities : [raid1]
md0 : active raid1 sdb1[2](F) sda1[0]
732572608 blocks [2/1] [U_]
Smartdは何も報告していないので、smart属性を確認しましたが、sdbとsdaで異なる（失敗）唯一の疑わしい読み取りは次のとおりです。
sda:
191 G-Sense_Error_Rate 0x0022 252 252 000 Old_age Always - 0
sdb:
191 G-Sense_Error_Rate 0x0022 098 098 000 Old_age Always - 27650
サーバーラックのGセンスエラー？たぶんセンサーが故障していますか？
しかし、両方ドライブには別のファンキーな読み物があります：最新の短いオフラインテストは「中断（ホストリセット）」であり、新しいものを開始した場合、たとえばsmartctl --test=short /dev/sda、選択的セルフテストログは次のことを示しています。
SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS
1 0 0 Self_test_in_progress [90% left] (0-65535)
ただし、この短いテストは終了することはなく、数時間後でも状況は同じままです両方ドライブ。これはドライブのファームウェアのバグでしょうか？または、コントローラーに障害が発生していますか？
短いセルフテストを実行した両方のドライブの完全なダンプは次のとおりです。

ヒントをありがとう！
ここではコントローラーエラーが発生する可能性があります。時間をかけすぎる前に、すべてのケーブルを取り付け直すことをお勧めします。時間の経過とともに何かが緩み、問題を引き起こしている可能性があります。
また、smartdについて言及しました...セルフテストを実行しようとしているときにこれを無効にしましたか？これが手動テストに干渉している可能性があります。
Sdbが失敗したと見なされる理由についてdmesgに何かありましたか？どちらのドライブも正常性をPASSEDとして報告しているようであり、mdadmが実際にSMARTデータを使用してドライブの状態を判断しているとは思わない。
