# Linux启动进入急救模式
**报错如下**
```bash
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
```bash
journalctl -r
```
日志如下
```bash
# 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
```bash
ls -l /dev/mapper
```
3. xfs 修复
```bash
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
