[Ocfs2-users] ocfs2 datavolume option and oracle

[jcollins at ip-acd.com]

I'm working with Ubuntu 8.04.1 LTS.  The kernel is 2.6.24 so it should 
have the memory leak correction.  However, that leaves the problem of it 
also having ocfs2 module version 1.3.3.  Which if I'm understanding 
things correctly means not supporting the datavolume mount option which 
is needed for Oracle RAC, right?
