smartmontools 报告 RAID1 配置中使用的驱动器上不可读扇区的数量不断增加。我认为 LSI MegaRAID 控制器也会检查其磁盘驱动器的 SMART 状态，因此应该将驱动器识别为故障并将其标记为脱机？
smartctl -d sat+megaraid,7 -a /dev/sda 的输出：

请告知 RAID 控制器行为是否正常或是否存在错误配置。控制器应处于出厂状态，我只将四个物理磁盘配置为两个 RAID1 卷。
无论如何，坏的磁盘都会被替换。
更新：我了解到实际上有一种方法可以了解此类错误（见下文），但是我认为此类信息将显示在更突出的状态信息中，而不是埋在日志文件中。
看来 RAID 控制器没有标记该磁盘，因为它仍然可以从该错误情况中恢复。
答案1
要查看 RAID 控制器日志，请运行以下命令：
/opt/MegaRAID/MegaCli/MegaCli -AdpEventLog -GetLatest 1000 -f events.log -aALL
events.log 文件包含如下条目，表明磁盘存在问题：
