If / etc/fstab is correct, you can simply type:
mount -n -o remount /
But if / etc/fstab is wrong, the device name and possibly the type must have to be given too: e.g.
mount -n -o remount -t extX /dev/sdaX /
Where,
extX is your filesystem type
/dev/sdaX is the partition you want to mount
To see all your available partitions just type ls /dev/[sh]d*.
