I think (though I'm definitely not certain) that if your setup were correct, you'd have Primary/Unknown and Secondary/Unknown after pulling the ethernet cable. i.e. heartbeat would know which is the ``good'' node and migrate services to that one, but drbd wouldn't have a way to mirror the data. I don't have a similar setup to test my claims though, since I am not using the same interface both for the drbd data and the service itself. I have a separate crossover (so to speak) gigabit ethernet connection for drbd and heartbeat (in reality two bonded gigabit ethernet), along with a serial one and a separate interface for providing the actual service. ipfail/ping only uses the ``service'' interface to make decisions about who should run the service. Maybe someone else can help you with this one, either here or on the linux-ha mailing list. > > > My ha.cf: > > /logfile /var/log/ha-log > logfacility local0 > keepalive 2 > deadtime 30 > warntime 7 > initdead 120 > serial /dev/ttyS0 > baud 19200 > udpport 694 > bcast eth0 > auto_failback off > node OV-HA1 > node OV-HA2 > ping 192.168.0.254 > respawn hacluster /usr/lib/heartbeat/ipfail > apiauth ipfail gid=haclient uid=hacluster > deadping 15/ > > Thanks, > Matteo > > ------------------------------------------------------------------------ > > _______________________________________________ > drbd-user mailing list > drbd-user at lists.linbit.com > http://lists.linbit.com/mailman/listinfo/drbd-user >
