我在 Linux 上的 AVAGO MegaRAID SAS 9361-8i 上幾分鐘內經歷了一系列奇怪的磁碟「故障」。在此期間，熱備用驅動器從未啟動。忽略一些不相關的 JBOD 驅動器（看起來不錯），定義的 DG 是 RAID6。當第三個磁碟發生故障時，DG 離線。由於磁碟一起故障的速度太快，我懷疑它們不是真正的問題。我想也許我可以嘗試恢復 DG。
我重新啟動了設備，現在磁碟被標記為“外部”：

請注意，我不知道為什麼它們被標記為“外國”；我沒有移動、新增或刪除任何磁碟。

當我嘗試導入時，它失敗並出現錯誤：

我想也許嘗試強制預覽的離線驅動器聯機，但是：

這三個都會發生這種情況。
有什麼辦法可以恢復這個嗎？另外，有誰聽過這種突然級聯的磁碟故障（沒有熱空間旋轉）？
