I have a DHCP HA setup on two gateway devices. I also have a script that simulates clients requesting IPs from these servers. I want to test out the behavior of these gateways in partner-down state, that is when one of the servers is down, I manually set 'my state' as partner-down in the dhcpd lease file of the other server.
According to ISC DHCP logic, when a device is in partner-down state, it should be able to consume all backup leases and allocate them if clients request for IPs. However, the lone peer is not able to consume the backup leases, and is only assigning free leases to the clients that come in. This results in the backup leases not being used at all. I have validated that 'partner-down' is being set correctly in the lease file, and also made sure that the other peer is actually down and unable to assign leases.
Has anyone faced this error before? Is it due to a code logic error in the isc-dhcp code or could it be something else?
