So what you're saying is something is mounted on to a directory that
had
data in it before the mount. How do I see the data being hidden
without
unmounting the point?
You can't. You must unmount. You should be able to do this from single user mode if the file system cannot be unmounted under multiuser mode (eg /usr, /var, etc.). Usually other mount points can be unmounted, but depends on what is running on the system at the time. Unmounting /home would require that you kick all users off for example, unmounting /var/www would require stopping apache, etc.
This is absolutely untested but it could work: mount / to /mnt and delete the data from there. Dig into mount(8) and test this somewhere outside the production area:
--bind Remount a subtree somewhere else (so that its contents are available in both places). See above.
But again, this is untested and nothing more but a wild guess.
