The servers will balance the pool(s) between them. It's actually fun (for personal preference values of "fun") to tail the logs on both servers after starting the slave and watch dhcpd communicate.
So they "only" balance the pool and no 1:1 assignment from IP:Host-MAC-address.
Sorry, I had to re-read your original posting ...
The best way to set this up is to have a minimal dhcp.conf on both servers that contains global definitions and the failover section, and then includes another config file that contains everything else - the shared-network block with pools, groups etc. This second config file is the same for both servers and you need to keep it in sync.
Do you know if you have to do anything special in the case where the primary server has been down for a while and is then brought back up? That is, does the backup automatically re-sync the database with the new leases that have been given out, or does it not have to?
