Duplicate assignments to different clients also won't be established if you=

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.
