Thats not an option, because only the base distro is free. To download
updates you have to buy a support contract.

That seems  a reasonable solution. I might try it...

My "personal" opinion, is that as oracle decided not to fix such a
serious bug, then OCFS2 is practically  unsable for EL5...So the
statement that "oracle has not dropped support for OCFS2"  is
relevant...to me...

I current have two productions clusters running Scientific Linux and
OCFS2. Both of them are running very well, and i'm very happy with the
OCFS2. But i can't just
wait for the bug to appear. I have to take precautions before the
filesystem starts to have problem.....
