Yesterday, I modified the /etc/fstab file in order to mount my usb thumb driver atomaticly. dev is sba1 and the mount point is /mnt/usb. I cannot remember what other parameters had been used, as I got something emegene to do.
I just use "halt -n" comman to shutdown the PC.
Today, I found that it cannot boot into the system.
when it checking root filesystem:
fsck.ext3:ABEL=/:
The superblock could not be read or does not describled a coorect ext2 file system. If the device is valid and it realy contains an ext2 filesystem (and not swap or ufs or something else)then the superblock is corrupt and u might try running e2fsck with an alternate superblock .
e2fsck -b 8193
NO SUCH FILE OR DIRECTORY WHILE TRYING TO OPEN ABLE=/
System info:
readhat AS 3.0
root(0,1)
kernel /boot/Vmlinuz-2.4.21-4.EL ro root=LABEEL=/
initrd /boot/initrd-2.4.21-4-EL.img
P.S. Just a LINUX os is installed in this pc.
Help...what should I do now??? don;t want to format the hardisk and reinstall the whole system.
