所以我遇到了这个麻烦，我相信我丢失了所有的数据..但是我发现了一个月前制作的旧 mdadm --examine --scan 文件和一个旧的 mdadm.conf....是否可以使用这两个项目来修复我损坏的阵列？？
我目前所做的是在链接中这里。
以下是我发现的旧 mdadm --examine..

我为每个驱动器执行的当前 mdadm --examine 现在显示不同的 UUID？
Array UUID : 1c0d0df7:d321d9aa:1c920da2:2baa5067
在尝试排除故障之前，我做的最后一件事是发出 apt-get update 和 upgrade，然后重新启动。
谢谢你们！
