:-) I just finish similar configuration in active/active cluster

Debian 6.0
Active/Active Configuration with ocfs2 1.6
Samba (active/pasive node)
Virtualbox (Active/pasive node)
Dovecot/exim/Apache/DNS (Active/Active).

Up un running :-)

My client don't want use pacemaker, and I create some scripts for:

1, wait some time to sync drbd and try to mount ocfs2..
2, boot samba checking if the other node has the service
3, Virtualbox headless that check if the service are boot.

Regards!
