Good morning together,
last week I did a configuration change on a 2.0.0 KEA server and adding more
subnets for DHCP addressing (as I did before). After adding new subnets after
the already configured subnets, everything was working fine. Then I added new
subnets before the already configured subnets in the config file and then the
DHCP server is ignoring the configured DHCP reservations fort he clients. So
the DHCP server was giving clients, which have a reservations in the config, a
new DHCP lease and a new IP address. I tested the configuration on a test
system and I was not recieving any error when I start the DHCP server, so there
was no configuration error and same result on the live system. The DHCP service
itself and the DHCP addressing is also working fine. Only the reservations were
not work anymore. I did some tests and I can reproduce that error on the test
system.
So my question are now, ist tehre a command for reordering the subnet
configuration or for re-reading/rebuilding the subnet configuration on the DHCP
server? Or does anyone have the same error?
The system is a Ubuntu 20 with KEA 2.0.0 in an HA setup. The configuration is
config file and the leases are saved on a MySQL database.
