I am sorry for the very late reply, but I don't login very often. If you are sill interested:
I have installed ocfs2 from debian reps. Look for configs in the next message.
Please keep in mind, that it is very important in which order services start up or shut down (for example drbd should shut down after ocfs2). I did some modifications in this regard.
