Hm, I thought heartbeat was doing that on make install these days.
Perhaps only in the CVS version.

Ah sorry about that. I assumed you already had it set, but yes it is
necessary. The reason is that we want to give ipfail the controls over
whether to failover. Without the nice_failback behavior, hearbeat would
immediately failback the resources because for all it's concerned, the
node is still alive (we can communicate.) ipfail alters this
assumption, and induces failovers because of network failures.

No problem, glad it works.
