Title: fstab error on booting
Post by: koshakis on September 05, 2009, 10:05:06 AM

...  startup, I'm getting the following error:

fsck.ext2: Bad magic number in superblock
is corrupt and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

No idea how to fix this.
There is one SATA hard drive and run SME 7.4

Any suggestions how to fix this

Looks like a problem in the file system.

I'm not familiar with the command e2fsck and search on google shows some thing about not running it on

mounted filesystems , please wait for some one more experienced with the command to help....

does the boot stop and ask you for a password?

do you have a backup?

ok..

assuming you have a standard SME setup with lvm, give root passwod and run the suggested command using /dev/mapper/main-root as device; you could be requested to say 'yes' many times

at the end of the process, reboot and check your data..
