我有一个德班服务器（最新版本和所有安全更新已完成），3 年前我创建了一个超过 3 个磁盘的 RAID-5 mdadm。它仍然有效，但我现在从该工具中收到错误logwatch。今天才注意到，所以不知道它存在多久。此外，任何日志文件中都没有错误。我使用整个 RAID-5，lvm所以我不知道如何使用“中给出的解决方案”我的 RAID 1 在重新启动后总是将自身重命名为 /dev/md127 | Debian 10”。
我也跑了update-initramfs -u，但这似乎并不能解决问题。
mdadm: 无法打开 /dev/md0: 没有这样的文件或目录
所以我开始调查，以下是我发现的事情。

我应该怎么办？我可以在文件中更改md0为吗？我应该只将 的输出添加到该文件中吗？md127/etc/mdadm/mdadm.confmdadm -D --scan
