我收到的消息/var/log/messages
似乎表明 /dev/sdc 有问题(除了最后两个之外):
$ sudo grep sdc /var/log/messages

但是,上面最后两行,还有:
$ cat /proc/mdstat

似乎表明 /dev/sdc 不再有问题。
那是对的吗?
答案1
不幸的是没有。
最好的办法是(如有必要)安装 smartmontools。使用它,您可以运行smartctl -a /dev/sdc
警告:忽略它可能会说“通过”,这仅意味着它已成功读取驱动器的 SMART 数据,但这并不意味着没问题。
您想要查看离线无法纠正的原始读取错误和重新分配的扇区。
驱动器可能会出现故障并处于故障边缘,但可以将其重新放入阵列中,但在这种情况下可能会再次出现故障。同样,即使是断电也可能导致阵列不稳定,因此可能没什么大不了的。让我们知道智能数据检查的进展如何。
