Linux系统问题排查与解决指南

1. 根文件系统问题修复

当Linux系统启动时，可能会遇到根文件系统的问题，例如 /etc/fstab 中的拼写错误。尝试启动Linux时，可能会出现如下错误信息：

Initializing USB keyboard:                              [  OK  ]
Initializing USB mouse:                                 [  OK  ]
Checking root filesystem
LBEL=/:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
      e2fsck -b 8193 <device>
fsck.ext3: No such file or directory while trying to open LBEL=/
                                                        [FAILED]
