Hi there, <br>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. <br>
I've both services actives in both nodes. <br><br>[root@nproxy01 /]# crm status<br>============<br>Last updated: Wed Nov 16 10:02:32 2011<br>Stack: cman<br>Current DC: nproxy01 - partition with quorum<br>Version: 1.1.2-f059ec7ced7a86f18e5490b67ebf4a0b963bccfe<br>

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. <br><br></blockquote><div><br>With this parameter it's sufficient to do Load Balancing or againts it's necessary install ldirector? <br>
