mdadm 上的失败事件

Question

我收到这个错误：

This is an automatically generated mail message from mdadm running on host.xx.xx

A Fail event had been detected on md device /dev/md2.

It could be related to component device /dev/sda2.

Faithfully yours, etc.

P.S. The /proc/mdstat file currently contains the following:

Personalities : [raid1]
md2 : active raid1 sdb2[1] sda2[2](F)
523200 blocks [2/1] [_U]

md4 : active raid1 sdb4[1]
1901261760 blocks [2/1] [_U]
bitmap: 5/15 pages [20KB], 65536KB chunk

md3 : active raid1 sdb3[1]
51198912 blocks [2/1] [_U]

未使用的设备：

然后我收到了另一封电子邮件：

Subject: FailedOpenDevice
Device: /dev/sda [SAT], unable to open device

我如何知道我拥有的 2 个磁盘中的一个是否有问题？

Answer 1

How can I know if I have a problem in one of the 2 disks I have?

FailedOpenDevice Device: /dev/sda [SAT], unable to open device

您的 /dev/sda 有问题。您在 mdstat 中看到 sda2[2](F)，(F) 表示该光盘 (/dev/sda2) 有故障。查看您的 dmesg 以了解更多错误。
