Hi Devin,

thank you very much for your answer.

I know that the "construct" we are building is quite complicated.

The problem is, that the active network (10.20.10.x) is too small to
cover both locations (in real we only have a /26 subnet available) and
we can not change/move this (public) addresses to an other range.

In addition a NAT-translation over a router is not possible, the servers
have to be accessible directly via their public ip-address, that has to
be the cluster-ip.

So we have to deal with two different networks in the two locations
(10.20.11.x/10.20.12.x) and create an "overlay" for the current
ip-addresses :-(

The current status is, that I added a modified the
heartbeat-Route2-script that also allows the "metric" as parameter and
with this it works as expected.

But I am really fighting with the new corosync/pacemaker, for me the old
heartbeat (1) was much easier and gave me all functionality I needed. So
I make progress, but quite/too slow ...
