系统开机即进入救援模式，报错如下：

Generating "/run/initramfs/rdsosreport.txt"

Entering emergency mode. Exit the shell to continue.

Tupe "journalctl" to view sustem 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.

通过journalctl -n 30 查看系统日志如图：

解决方法：

umount /dev/sda3 //如果没有进入救援模式，需要先umount,然后修复
xfs_repair -v -L /dev/sda3
reboot
