[Linux-cluster] Higher Grained Definition ofIP AddressAssignments

[Kit Gerrits]

In that case, might it be easier to simply use the host IP adresses and not
the cluster IP's?
(the application will need to handle up/down events itself)

I've spent the past year architecting an HA cluster with RHCS and it's
working wonderfully. I have not seen anything superior.

Due to a new customer-driven feature of our software, we need to add the
ability for a cluster service/resource group to have up to eight distinct
IPs on one particular network due to the software being made highly
available via RHCS performing its own load balancing. Placing the load
balancing elsewhere is not an option due to the nature of the product.

Regarding "OCF_RESKEY_," will google more on this and appreciate the tip.
Must work this out some way.

This is a resource agent script. What attributes a resource agent

There is no attribute interface. The agent will add the additional

address to the first interface that is in the same subnet.



You could edit the script and add a parameter interface yourself. Add

a new parameter into the XML at the beginning and access it in the

script with OCF_RESKEY_...



I don't understand what you are trying to do. If you are only handling

network interfaces as services, then rhcs is most likely the wrong

tool. If you would explain your goal we could probably suggest other

solutions.
