A quick tip for you, since this bit you: you don't want to umount /. That will do things like remove your access to the very program you need to remount it rw: mount. So, that bit actually saved you. The option you needed was:

# mount -o remount,rw /

This will remount it rw in place. I have had to employ it in quite a few similar "misbehaving drive" situations.
