Ocfs2 users - Jun 2006 - ocfs2 on coraid?

Anyone tried to use ocfs2 on a coraid?  So far I've found that I had  
to crank the heartbeat threshold up.  Anything else I should know about?

I'm running the ocfs2 version that comes with kernel 2.6.16.7 (is  
there something more recent I should use?) and ocfs2-tools and  
ocfs2console both v1.1.5 backported to debian stable.  Oh, and a  
coraid SR1520 with ~6T of space in a single volume. (ocfs2 will  
handle that, right?)

  Thanks,
