Since I just went through this very exercise, some feedback.
OCFS v2 is not supported at this time for production use.
On my Opteron based systems I experienced crashes when I tried to
unmount ocfs v2 volumes from one of my nodes.
OCFS v2 is supposed to be a posix compliant FS and can host regular
files.
OCFS v1 support is not available for RHES4.
In the end I implemented OCR and CSS files as raw devices and it works
great.
If you want to implement shared ORACLE_HOME you are out of luck though.

I think your best bet is a network file system (ie. NFS) until OCFS v2
is stable. You could also check out RedHat GFS, I have zero experience
with that though.
