Linux启动进入急救模式

报错如下

Generating "/run/initramfs/rdsosreport.txt"

Entering emergency mode. Exit the shell to continue.
Type "journalctl" to view system logs.
You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot after mounting them and attach it to a bug report.

问题分析

XFS(dm-0)有元数据损坏。

问题解决方案:

  1. 查看系统日志

    journalctl -r
    

    日志如下

    # 查看红色报错()内名称
    
    XFS (dm-0):******
    # 或如 vda1 类报错
    
  2. 使用()内名称查询对应映射区

    ls -l /dev/mapper
    
  3. xfs 修复

    xfs_repair -v -L /dev/dm-0
    
  4. 最后退出急救模式重启启动成功

完美解决
