How to recover corrupted fstab file in Linux

How to recover /etc/fstab in Linux

Applies to:

            Enterprise Linux – Version: 5

Description:

            I have an error in my /etc/fstab file and when I restart the computer it directly went to the “Repair filesystem” prompt asking the root password. When I went to correct the errors in the /etc/fstab file it is giving the following error:

Unable to open swap file for "fstab" , recovery impossible.

Changes cannot be saved.

Solution:

Boot up from any LiveCD, mount / partition and edit /etc/fstab file.

OR

I restart the computer it directly went to the “Repair filesystem” prompt asking the root password, enter root password.

Before editing fstab mount / on rw mode.

# mount -w -o remount / # Write allowed

After that you should be able to fix the fstab, and restart the computer.
