You won't be able to remount it read-write until fsck is run against
it.  You're best off unmounting it completely (if possible), running
fsck against it, and remounting it.  Rebooting should also fix it,
assuming a valid entry in /etc/fstab.

I'm not aware of any known bugs that would have caused the corruption. 
You haven't seen any i/o errors from the disk, have you?
