No, on Unix you use only directories. It doesn't matter if, a directory is a
mount point for a fs.
For an developmentsystem i would create 2 fs with 3 GB and 4GB and mount it
on /oracle and /oracle/stage.

No, if it's possible create a seperate fs an mount it on /oracle

Before you mount the new fs (/oracle and /oracle/stage), rename the old one.
(mv /oracle /oracle.org) after this you can mount your new fs and copy (cp
-rp /oracle.org/* /oracle)
