dhcpd: failover peer pool-name: address not available

[Glenn Satchell]

Are you running the same version of dhcpd on both systems? The failover 
protocol in 3.0.x and 3.1.x are not compatible. Maybe the server upgrade 
   enabled the default dhcpd or something similar?

In server/failover.c that message seems to only happen when failing to 
initiate the failover connection to the peer. So check the hostname 
resolves to the correct IP address, and that you can ping the other host.
