Hi, I have created the dhcp failover in my local environment it worked
fine. I need to add few more line to config, so I stopped dhcpd services on
them and updated the configs, Now I started dhcpd on the appliances one
after the other, but it ran into issue dhcpd is not granting leaes now, In
the logs it is saying failover link start up time out. Does any one has any
idea on how to get out from this case.
Any help would be appreciated
Thanks

Post some actual log lines with the error.
Post the output of "head -15 /var/lib/dhcpd/dhcpd.leases" for each server.
What changes did you make?

Hi Bill
I just added one more new subnet with scope in the dhcpd.conf file and then
cross checked the file with syntax check command Ex: dhcpd -t -cf
dhcpd.conf
It doesn't not gave any syntax error then i restarted the dhcpd

Subject: DHCP client keep expired leases if client suspend
Message-ID:
<CALr0QzETvgeKo3+5vic47zj+J00NvT5jvkb2MK=znumwywb...@mail.gmail.com>
Content-Type: text/plain; charset="UTF-8"
Hello.
I have a problem with my Debian 10 Buster clients using the last
version of the ISC dhcp client (4.4.1).
Here the problematic scenario :
-> My DHCP server give a 8 hours lease to a client.
-> The client say that it will renew the lease in 4 hours.
-> One hour after the client suspend (not hibernate).
-> The next day (more 24 hour after) a wake the client by Wake-On-Lan.
Instead of request a new lease immediately with DHCPDISCOVER, the
client wait for three hours more before renewing the lease. So the
expired lease it kept during 3 hours. This is like the client use only
the "running elapsed times" and don't notice the time elapsed during
suspend.
But that's not completely true because the client make a DHCPDISCOVER
enstead of a DHCPREQUEST. So the client notice that the lease has
expired. But too late.
I don't know where report the bug :
-> Is this a ISC dhcp client problem ?
-> Or is there a systemd problem that does not signal the suspend to
the DHCP client ?
-> Or a network-manager problem ?
Thanks for any help !
Baptiste.

Thst is no guarantee. There are a few config errors that won't be picked up by
the parser.
