[ClusterLabs] HA static route

[S0ke]

So I switched the resource to use the following:

<primitive class="ocf" id="p_src_eth0DEF" provider="heartbeat" type="Route">
<instance_attributes id="p_src_eth0DEF-instance_attributes">
<nvpair id="p_src_eth0DEF-instance_attributes-device" name="device" value="eth0"/>
<nvpair id="p_src_eth0DEF-instance_attributes-gateway" name="gateway" value="172.16.2.1"/>
<nvpair id="p_src_eth0DEF-instance_attributes-source" name="source" value="172.16.2.8"/>
<nvpair id="p_src_eth0DEF-instance_attributes-destination" name="destination" value="default"/>

When I do a failover from the master to slave. It seems to add a route of 0.0.0.0/0 but still fails to start the p_src_eth0DEF resource with the same error.
> stderr: RTNETLINK answers: File exists
> stderr: ERROR: p_src_eth0DEF Failed to add network route: to default dev eth0 via 172.16.2.1 src 172.16.2.8
> stderr: DEBUG: p_src_eth0DEF start returned 1

If I remove the 0.0.0.0/0 and manually add the route I want in everything is fine. I did also remove the default gateway from the ifcfg-eth0 file as it was using 172.16.2.1 as the default gw. Still no luck.

Am I using this correctly? Or does it need to be RouteUp?

So even if the default gateway is set in /etc/sysconfig/network-script/ifcfg-eth* that could cause it?

The question is why does the route exist already? I you want it to be
managed by Pacemaker then you need to remove it from any other startup
scripts that create that route.
