我的服务器位于 Hetzner，使用他们的 Ubuntu 14.04 部署映像，据我所知没有分区加密。机器使用 2 个板驱动器，并配置为软件 RAID。错误已经出现了一段时间。我没有足够的知识来查明我的 Ubuntu 14.04.5 这种邪恶行为的根源。当我运行时apt-get autoremove，控制台输出以下内容：
apt-get autoremove

我发现值得研究的是 grub-probe 尝试使用的驱动器 idgrub-probe: error: disk `mduuid/00db37a2ad5b8d86c2b04f8cadb67df3' not found.和 cryptsetup 打印：cryptsetup: WARNING: failed to detect canonical device of /dev/md/2让我研究 fstab、mtab 和 blkid。

我使用这台机器托管网站，想修复它而不是全新安装 16.04。如果无法修复，那么我别无选择，只能备份所有数据，重新安装并从头开始配置。
请帮忙。
