freenas raidファイルサーバーの問題を分析する最良の方法は何ですか？
freenas 9.2.1に問題があります。今日故障しました。 zfs jbod raid 2でファイルサーバーを実行します。問題の原因が正確に何であるかよくわかりません。システムが起動しますが、応答速度はかなり遅くなります。ログに完全に間違ったものが見つかりません。だから、エラー分析をどこから始めるべきか、どのように解決するのかわかりません。
問題は、システムがクラッシュして非常にゆっくり反応することです。 pyhonが死んだ後、freenasのWebインターフェースもクラッシュしました。
Freenasは、バックアップ用に追加のドライブ（2TB）が接続されているUSBスティックにインストールされます。残りの4つのドライブはzfs raidで実行されています。
ハードドライブにスマートエラーが表示されます。したがって、この状態でドライブを交換するのが最善の方法であるかどうかはわかりません。これらの問題をどのように解決できますか？それが問題の原因であることを願っています。

複数の顧客にDRDY ERRエラーが発生しました。認識された状況は、速度低下/パフォーマンスと高いRaw_Read_Error_Rate（非常に高い数値）です。
残念ながら、これらのエラーは通常深刻ではなく、ファイルのコピー速度は42〜100 MB / sと予想されますが、60〜90秒以内に2 GBのデータのみをコピーすると、速度が2 MB / s未満に低下し、失敗が発生します。実際、これはSATAコントローラの問題です。
ログを確認した後、ハードウェア障害に対して必要な措置を講じました。マザーボードを交換し、RAIDコントローラを交換し、もう一度既存のOTC HDDを工場認証ハードウェアに交換しました。適切なメンテナンスにより、すべてが完璧で素晴らしく迅速です。コストは高いが。
