Ubuntu 12.04 服务器软件 RAID1-故障备用-智能输出通过-困惑

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:

这是 parted l 的内容,您可以看到我的分区

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:

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)。
