最近偶的 Ubuntu 无法启动和现象：
***An error occured during the file system check
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.

UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)

Press enter for maintenance
(or type Control-D to continue):
输入 passwd 后进入 (Repair filesystem)#

运行fsck -y / （因为修复时会问是否修复，所以要加上-y参数。）
成功修复。
注意：在修复其它filesystem时要umount掉运行该命令。
