Hi,

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?

Michael.
