Sometime we can misconfiguration when configurating the /etc/fstab, this is the way how to fix the fstab:
Enter the Root password of the OS and it the “Repair filesystem” prompt appear..
We need to delete or change the misconfiguration line inside the /etc/fstab, it’s readonly file.. we need to :
Repair filesystem # mount -w -o remount /
after remounting the “/” , now try to edit the /etc/fstab by using vi editor
Repair filesystem # vi /etc/fstab
Change the line you need and save the file with “:wq!“, and the reboot the system.
