驅動器出現故障，但 LSI MegaRAID 控制器未檢測到它

smartmontools 報告在 RAID1 配置中使用的驅動器上有越來越多的不可讀扇區。我認為 LSI MegaRAID 控制器還會檢查其磁碟驅動器的 SMART 狀態，因此應該將驅動器辨識為故障並將其標記為離線？

smartctl -d sat+megaraid,7 -a /dev/sda 的輸出：

請告知 RAID 控制器行為是否正常或某處是否存在配置錯誤。控制器應該處於出廠狀態，我只將四個物理磁碟配置為兩個 RAID1 卷。

無論如何，壞盤都會被更換。

更新：我了解到實際上有一種方法可以了解此類錯誤（見下文），但是我認為此類資訊將顯示在更突出的狀態資訊中，而不是隱藏在日誌文件中。

似乎 RAID 控制器沒有標記該磁碟，因為它仍然可以從該錯誤情況中恢復。

要查看 RAID 控制器日誌，請執行以下命令：

/opt/MegaRAID/MegaCli/MegaCli -AdpEventLog -GetLatest 1000 -f events.log -aALL

events.log 文件包含如下條目，表明磁碟存在問題：
