additional remark:

With some tweaks I made my cluster start two resources (i.e. IP1 and IP2) at the same time. But it takes about 4 seconds to that the cluster starts the next resources (i.e. IP3 and IP4).

Did anybody see this behaviour before?

Why does my cluster do not start all "parallel" resources together?
