Hi,

on the list was a discussion about resource capacity limits. Yan Gao also 
implemented it.

As far as I understood the discussion the solution is to attach nodes and 
resources capacity limits. Resources are distributed on the nodes of a cluster 
according to its capacatiy needs. They would be migrated or shutdown if the 
capacity limits on the node are not met.

My question is: Can the capacity figures of the resources be made dynamically?

So i.e. for every monitor operation the CRM updates the capacity usage figures 
of the resource. So the cluster could react dynamically oin the actual 
capacity of a resource.

Greetings,

Michael.
