[ClusterLabs] Working with 2 VIPs

[Louis Chanouha]

Hello,
I'm not sure if this mailign is the proper place to send ma request, 
please tell me where i should send it if not :)

I have an use case that i can't run acutally with corosync + pacemaker.

I have two nodes, two VIP and two services (one dupplicated), in order 
to provide an active/active service (2 physical sites).
On a normal situation, one VIP is associated to one node via a prefered 
location, and the service is running one the two nodes (cloned).

On failing situation, i want that the working node takes the IP of the 
other host without migrating the service (listening on 0.0.0.0), so when :
  - the service is down - not working
  - the node is down (network or OS layer) - working

I can't find the proper way to conceptualize this problem with 
group/colocation/order notions of pacemaker. I would be happy in you 
give me some thoughs on appropriate options.


Thank you in advance for your help.
Sorry for my non-native English.

need it.
