[DRBD-user] Heartbeat configuration for OCFS2 on DRBD

I have set up a replicated filesystem using OCFS2 on a DRBD device in  
Primary/Primary mode with a dedicated GBit interconnect. It seems to  
work like a charm.

Now comes heartbeat. What are best practices for setting this up in  
the Primary/Primary situation? In particular:

1) I want both nodes to come up as primary on boot How to ensure this?

2) Should I leave mounting to heartbeat?

3) Though a link failure is highly unlikely, I would like to avoid a  
split-brain scenario in case it does happen. Does heartbeat ensure this?

Any advice is much appreciated.
