Active/Passive mode _always_ comes with downtime at a failover. You cannot reduce it to zero, nor is pushing this optimization very senseful (but instead you can easily break your system with setting timeouts so low that nothing will ever work or respond after that). In this A/P mode it doesn't really matter to have 10 or 20 seconds downtime as it also depends on the hardware, drbd filesystem, used data, etc. If you want to experience "real" high availability without any downtime you'll have to go the Active/Active way and/or use Load Balancing.
