我认为我的阵列上的某个硬盘出现了问题，我只是想排除故障。
它说有故障的备用电源，然后重新启动后它只是说已删除：

我运行了 smartctl -a /dev/sdb2 并且它说我通过了，但是与我的工作驱动器相比，RAW_VALUE 数字确实很高。
结果如下：

答案1
实际上，您似乎尚未成功进行任何自我测试：
SMART Self-test log structure revision number 1
No self-tests have been logged. [To run self-tests, use: smartctl -t]
尝试运行smartctl -t long /dev/sdb。

驱动器发生故障，但故障程度不足以触发“SMART 故障”，因为所有与错误相关的数字都高于其故障阈值。RAID 故障事件最可能的原因是无法纠正的读取错误（SMART 属性 187）。
