[Pacemaker] Pacemaker Active-Active Load Balancing Issue

[IVAN GARCIA]

Hi there,
I'm configuring a cluster active-active for web proxy (SQUID), the proxy
will be 4 nodes but now I only have 2 nodes, I've configured Virtual-IP
with resource OCF:heartbeat:IPaddr2 and Squid in LSB resource mode, In
active pasive all works fine but in active-active mode I don't know,  why
the requests are not balanced?. All requests go to the first node.
I've both services actives in both nodes.

I've configured *clusterip_hash="sourceip"  *according to the documentation
that

Now we must tell the ClusterIP how to decide witch requests are processed
> by witch hosts. To do this we must specify the clusterip_hash parameter.

With this parameter it's sufficient to do Load Balancing or againts it's
necessary install ldirector?

Thanks in advance.
