Re: [Pacemaker] HA KVM over DRBD primary/secondary configuration

Hi Chris, No, you're definitely not missing anything. The 'pcs cluster cib' output isn't pretty. why there is an approach to build a new config-tool at all? Why not use the crmsh? Why it was dropped in the RHEL-build? Does it have some relevant disadvantages? -- To Answer please replace invalid with de ! Zum Antworten bitte invalid durch de ersetzen !

Re: [Pacemaker] Routing-Ressources on a 2-Node-Cluster
Hi, Because the nodes are located in different networks, each node needs it's own route-ressource, that is only valid if the node is passive and will be removed when this node goes active and gets the default route for the cluster-ip. I did not found any solution for this, so I'm going the other way. I added static routes with a high metric to each server: route add 1.2.3.4 via 10.20.11.1 metric 20 and route add 1.2.3.4 via 10.20.11.1 metric 20 When a server gets active, it will get the cluster-ip 10.20.10.70 and the default route to 10.20.10.1. In addition, the active node will get a new route via the cluster-ip with a lower metric, that overwrites the above static route: route add 1.2.3.4 via 10.20.10.1 metric 10 I tested this manually and it works as expected. There is just a small Problem: the heartbeat-route resource does not allow defining the metric :-( So should I change the /usr/lib/ocf/resource.d/heartbeat/Route, should I create a new start-script or is there any other solution?

Re: [Pacemaker] Routing-Ressources on a 2-Node-Cluster
Hi David, Why can't both your cluster nodes have 10.20.10.1 as their default route all the time? because the different locations have different networks, routers, IP-addresses etc. But to be always reachable from the outside, they need one common IP-address, that is valid on the active node. And only for the active node the 10.20.10.1 is the way to go out, the passive node does even not have any connectivity to the outside. There is just a little hole for getting updates and for the pingd-resource needed for the HA-functionality. This is done by a proxy and/or by routes and it is working as expected. Your configuration seems to have way too many moving parts and since you are making routing changes when the nodes become primary it is difficult Well, beside the servers that have to run on the active node, the only moving part is the cluster-ip, it's default route and an additional route. So I do not see too much complexity? Not 100% sure what you're trying to accomplish, but when a config is this complex it's usually not ideal. That might be correct, but this is not the problem I have. So any other hint what I should do to get the metric working for the route-resources?
