debian机器，开机遇到类似下面的错误
checking drive/dev/sda3: 92%(stage 4/5,25/85) fail
Flie system check falid
A log is being saved in /var/log/fsck/cherks if that location is writable.Please repair the file will now be started.
A maintenace shell will now be started Control-D will terminate this shew and resume system boot.

fsck died with exit status 4
这里描述的是磁盘检测错误，网上说是异常关机导致的。
然后尝试用下面命令执行，重启后系统正常了
先mount -no remount,ro /
再fsck.ext3 -y /dev/sda3
然后重启ok!
注意：网上说，不要直接执行fsck，这样会有危险，要在把设备unmount后执行。
