dhcpd in failover not reusing expired leases

[Robert Blayzor]

Providing a bit more info on this.... (sorry)

Primary .conf:

server-identifier 64.x.x.x;
server-name "foo";

failover peer "dhcp-failover" {
   primary;
   address x.x.x.x;
   port 520;
   peer address y.y.y.y;
   peer port 520;
   max-response-delay 30;
   max-unacked-updates 10;
   load balance max seconds 3;
   mclt 600;
   split 128;
}

include "/etc/dhcpd/include/common.conf";




Secondary .conf:

server-identifier y.y.y.y;
server-name "bar";

failover peer "dhcp-failover" {
   secondary;
   address y.y.y.y;
   port 520;
   peer address x.x.x.x;
   peer port 520;
   max-response-delay 30;
   max-unacked-updates 10;
   load balance max seconds 3;
}

include "/etc/dhcpd/include/common.conf";




and common is just our pool information, pretty basic:


subnet 64.x.x.x netmask 255.255.255.0 {
   option domain-name-servers x.x.x.x, y.y.y.y;
   option domain-name "foo.bar";
   option routers x.x.x.x;
   default-lease-time 7200;
   max-lease-time 7200;
   pool {
     deny dynamic bootp clients;
     failover peer "dhcp-failover";
     range 64.x.x.x 64.x.x.x;
   }
}
