Yes, it depends of what you have put in 'net.inet.carp.preempt' if it's net.inet.carp.preempt=0 than the backap will become master and stays that way and if it's net.inet.carp.preempt=1 then the "real" master will take over the IP address from backup server when he gets in the OK state -- One cannot sell the earth upon which the people walk Tacunka Witco
