[Linux-HA] Fw: Streamline Highly Availability and Load Balancing

[Denis Anthony Dowling/Twn/TUV]

Hi

I am trying to configure HA and LB as described in the "Streamline Highly 
Availability and Load Balancing" example provided on UltrMonkey's website. 
However, both servers start the resources described in the haresources 
file. Both enable the VIP as a secondary address on the ethernet card and 
populate the ipvs table with the real servers. It's as if they are failing 
to communicate with each other and assume that the other is unavailable. 
Following are the config files for both machines. 

I am using the configuration described in UltraMonkey 3 with Red Hat 
Enterprise 3.0 Update 4.

Thanks
Denis
