And what if they both allocate the same disk block to another
file, simultaneously ?

A mount option isn't enough to achieve your goal.

It looks like you want GFS or OCFS. Info about GFS can be found at:

        http://www.opengfs.org/
        http://www.sistina.com/ (commercial GFS)

Dunno where Oracle's cluster fs is documented.
