I can only start my Web-Application after running all ip-resources so the first ip-resource is offline in the meantime.

I don´t know how can I configure resource sets in crmshell exactly. For my information a resource set is called if 2 or more resources are in relationship in a colocation - is it right?

crm configure colocation c_parallel inf: (resource1, resource2, resource3, resource4....)

But in my crm_mon resources all resources successively start
