Hi,
I am using ISC DHCP in primary and failover mode and I am getting issue
that clients are not getting leases and when I checked for the service logs
I see as
Primary Logs:
==========
Aug 17 17:15:48 dhcp1 dhcpd[12130]: balancing pool f6f5f0 192.168.56.0/24
total 50 free 0 backup 0 lts 0 max-own (+/-)0
Aug 17 17:15:48 dhcp1 dhcpd[12130]: balanced pool f6f5f0 192.168.56.0/24
total 50 free 0 backup 0 lts 0 max-misbal 0
Aug 17 17:15:48 dhcp1 dhcpd[12130]: peer peer-host: Got POOLREQ, answering
negatively! Peer may be out of leases or database inconsistent.
Failover Logs
==========
Aug 17 17:14:48 dhcp2 dhcpd[1902]: balancing pool bf05b0 192.168.56.0/24
total 50 free 50 backup 0 lts -25 max-own (+/-)5 (requesting peer
rebalance!)
Aug 17 17:14:48 dhcp2 dhcpd[1902]: balanced pool bf05b0 192.168.56.0/24
total 50 free 50 backup 0 lts -25 max-misbal 8
pool response: 0 leases
I tried searching the forums and many of them suggested that there might be
inconsistency between the configuration file and leases database, I cross
verified the configs they are good and regarding the leases file can we
manually do any operation to make them in sync ?
I tried checking the status of the primary and failover in the lease file
but they are in normal-normal,
cat dhcpd.leases | egrep "my state|partner state" | tail -2
my state normal at 2 2021/08/17 16:41:09;
partner state normal at 2 2021/08/17 17:01:17;
Has anyone faced a similar issue/Any suggestions of how to fix the issue,
Can we manually send requests for the DHCP service to do the pool balance
and sync the leases for that specific subnet ?
Any help/suggestion would be much appreciated
Thanks
Kraishak

What is pool utilization? In the log it shows total 50 free 0 backup 0.
What is the range you declared ?
Regards

Hi Abdul Khader,
I have declared as follows:
Configuration file from primary
=========================
failover peer "peer-host" {
primary;
address 192.168.56.156;
port 647;
peer address 192.168.56.178;
peer port 647;
max-response-delay 30;
max-unacked-updates 30;
load balance max seconds 3;
mclt 1800;
split 128;
}
subnet 192.168.56.0 netmask 255.255.255.0 {
pool {
failover peer "peer-host";
range 192.168.56.5 192.168.56.54;
}
option domain-name "test.com";
option routers 192.168.56.1;
option subnet-mask 255.255.255.0;
}
Configuration file from failover
======================
failover peer "peer-host" {
secondary;
address 192.168.56.178;
port 647;
peer address 192.168.56.156;
peer port 647;
max-response-delay 30;
max-unacked-updates 30;
load balance max seconds 3;
}
subnet 192.168.56.0 netmask 255.255.255.0 {
pool {
failover peer "peer-host";
range 192.168.56.5 192.168.56.54;
}
option domain-name "test.com";
option routers 192.168.56.1;
option subnet-mask 255.255.255.0;
}
On the primary log it shows as :* total 50 free 0 backup 0*
*Aug 17 17:15:48 dhcp1 dhcpd[12130]: peer peer-host: Got POOLREQ, answering
negatively! Peer may be out of leases or database inconsistent.*
but in the failover log it shows as
Aug 17 17:14:48 dhcp2 dhcpd[1902]: balancing pool bf05b0
192.168.56.0/24 *total
50 free 50 backup 0 lts -25 max-own (+/-)5 * (requesting peer
rebalance!)
Aug 17 17:14:48 dhcp2 dhcpd[1902]: balanced pool bf05b0 192.168.56.0/24 total
50 free 50 backup 0 lts -25 max-misbal 8
pool response: 0 leases
because of some reason the pool is not getting balanced between the primary
and failover
Also I have a problem in tracking my thread previously from
*http://isc-dhcp-users
<http://isc-dhcp-users>* link I used to track and reply but now it is not
working, and tried searching the other links I found this
*https://lists.isc.org/pipermail/dhcp-users/
<https://lists.isc.org/pipermail/dhcp-users/> *to track but I cannot see a
reply option in that web page
