ocfs2

I have the following setup:

Two servers with DRBD running dual primary with OCFS2
Heartbeat with two virtual ips, one for each server
Round robin DNS to load balance NFS across the two vIPs

Shutting down Server1 for a period of time, cause Server2 to take over the vIP for failover. However, when Server1 returns - it takes over the designated vIP as soon as heartbeat gets connection again - even though the DRBD is running sync (and thus not up to date)

How can I configure heartbeat to perform failback as soon as Server1 again is in sync with Server2 ? (And not before)

Why do I see a large performance hit with DRBD?

I see a much larger performance hit with DRBD than their user manual says I should get. I'm using DRBD 8.3.7 (Fedora 13 RPMs).
