CentOS4.6 version of the system is very old, ext3 file system, file system is full, the deleted file does not release the space, it was useless to restart, use FSCK - y try to repair, the results cannot be launched, direct access to grub after boot, knock on the boot, appear error 8, the Kernel must be the loaded before booting.
Take the hard Disk to other machines, use Disk Genius to see, found that the partition in, only lost +/found directory, there are a lot of digital named subdirectory, again to find the file is still there,
The first time met FSCK addled the dish, head, how to deal with me
