Duplicate assignments are not a problem as long as you ensure that the client is the same.
Duplicate assignments to different clients also won't be established if your standby server has access to an identical lease database at the moment your clustering software determines that the primary server has failed, kills the primary, and places the secondary in service. A sufficiently long lease duration should also be as good as a static lease, in that case. Because all the important details are in the database. You don't have to have any coordination in the DHCP software; you just in some cases, need to exclude the DHCPD daemon from simultaneously being active on multiple machines. -- -JH
