We have slightly different problems but are both limited by the nature
of foremans dhcp-proxy.
If you create static leases using omshell then I believe the data will
be replicated to a failover dhcp server.
Forman will create new hosts using omshell.
The comment about DNS is only because foreman can cleanly interact with
DNS remotely.

You are completely wrong.
What we like to have is a second DHCP with a proxy where is talked to
using OMAPI by foreman so we have a replication about the static leases.
DHCP itself is unable to sync them this way and for Failover we need
to have 2 writes to 2 DHCP servers which are in clutser mode.
DNS is not involved here.

A standalone DHCP server without lots of extra software installed.
I do not want to install the whole forman-proxy on the DHCP or DNS
servers
As an asidethe isc_dhcp proxy does not parse correctly formatted
dhcpd.conffiles(I just filed a bug report).
Looking at omapi I could be convinced that it is impossible to get
thecurrent dhcp config informationremotely.

What do you mean by a standalone DHCP server ? The proxy handles
that when you installed the proxy on the DHCP server.
This goes about a second DHCP server that knows the same static
leases as the proxy knows for failover whent the primary, with
proxy, fails.

I have wondered about the same problem.
Since foreman needs to read and write the leases and config
files it means that you cannot have a remote standalone DHCP
server.

Hi,
I was wondering if someone has a workaround for DHCP
sync with failover.
As foreman writes to the leases file directly this is an
issue for syncing.
Can't we write to a config file we include to the
dhcpd.conf and
reload dhcp when the proxy did something to dhcp ?
Ideas are welcome.
Cheers,
Matt
