I have found that the "peer holds all free leases" is a catch-all that can also mean "it did not match the allow members of ... or some other restriction on the dhcp range".

Hi,

I have a pair of failover dhcp servers (4.2.4) which work fine for a long time.

Now I added some subnets (same config like the old working one) and in that

subnets I get on both servers:

Apr  2 12:44:52 dns1 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:52 dns1 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:56 dns1 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:56 dns1 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:52 dns2 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:52 dns2 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:56 dns2 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

Apr  2 12:44:56 dns2 dhcpd: DHCPDISCOVER from 3c:97:0e:b8:6d:40 via 172.21.166.1: peer holds all free leases

But the pool seems to be well balanced:

Apr  2 12:43:56 dns1 dhcpd: balancing pool 8019f8880 172.21.166.0/24  total 250  free 125  backup 125  lts 0  max-own (+/-)25

Apr  2 12:43:56 dns1 dhcpd: balanced pool 8019f8880 172.21.166.0/24  total 250  free 125  backup 125  lts 0  max-misbal 38

Apr  2 12:43:56 dns2 dhcpd: balancing pool 8019ef880 172.21.166.0/24  total 250  free 125  backup 125  lts 0  max-own (+/-)25

Apr  2 12:43:56 dns2 dhcpd: balanced pool 8019ef880 172.21.166.0/24  total 250  free 125  backup 125  lts 0  max-misbal 38

Does anyone have an idea what could be the reason for that?

Thanks,

Chris
