デバイス：/ dev / sda [SAT]、1現在読み取り不能（保留中）のセクター
RHELにソフトウェアRAID 1アレイがあります。このエラーが毎朝メールで送られてきます：デバイス：/ dev/sda [SAT]、1現在、読み取り不能（保留中）のセクター
Sda（またはsdb）でテストを実行すると、すべてが合格したように見えます。何か不足していますか？
mdstatはRAIDアレイに問題がないことを示しています。

あなたのSMART現在の保留セクターの値は1です。これは、ディスクに不良セクターがあり、ドライブファームウェアがそれを再割り当てできないが、再割り当てセクター数がゼロであるため、おそらくドライブが非常に健康でない環境で5年間稼働している場合でも回復可能-温度は最大72 C°です。
dd if=/dev/sda of=/dev/nullを使用してこの不良セクターを見つけてから、上書きしてセクターを再マッピングする必要があります。
