You should have run fsck at this point, and _then_ remounted it
read/write. As you discovered, mounting a filesystem read/write when
errors are present is not good.

In your situation, I would boot from the rescue floppy, and manually
fsck your partition(s). You could also mount them after fsck'ing, and
poke around to see if everything's where it ought to be; alternatively,
you could just reboot and cross your fingers.
You really shouldn't run fsck on a mounted filesystem, which of course
is problematic in the case of the root filesystem.
