使用Proxmox挂载虚拟机的E3服务器因为SSD硬盘掉盘导致多次启动崩溃，等到修复好硬盘问题发现Ubuntu虚拟机无法正常启动，开机显示如下错误

从报错内容看不出所以然来，但既然是因为掉盘导致的系统错误，那先尝试下修复系统盘，使用CD-LIVE进入系统

进入CD-LIVE系统后，查找相关系统盘并修复

Bash

❯ sudo fdisk -l                                                               ~

fsck是一个Linux修复磁盘工具，在修复过程会自行排查相关磁盘异常并提示是否修复，修复过程如图

修复之后可以顺利启动系统
