1) You cannot remount / because other filesystems are mounted on it (I
surmise this because you don't mention /usr or /home).

2) / is readonly either because you provided no options at all, or
there are errors.

Here's what I would do:

1) unb0rk your /etc/fstab.  the "errors=remount-ro" needs to be there.

2) reboot.  pause lilo or grub and boot with "linux emergency" (replace
linux with the label of your default image)

3) enter the root passwd when prompted.

4) run "fsck /dev/sda2"

5) run "mount -n -w -o remount /dev/sda2 /"

6) type "exit"
