[Linux-cluster] Problems running service exclusivly

[Hansjörg Maurer]

Hi

I am trying to get the following config to work.

4 node cluster with
1 node providing a mysql service (only to nodes (bs1 and bs2) have the 
hardare to do so)
2 nodes providing a custom service (the same service on each node (bi1 
and bi2))
1 node fallback for both services

It is important, that on every node ony one service is running.
I created the following cluster configuration (RHEL4U1),
but the exclusice flag seems not to work.
I have created three priorisised restricted failoverdomains (one for 
eache services).
I assigned each service to one failoverdomain (with run exclusively on),
but if I start the rgmanger. als services are running on one node.
I can move them by hand to the right nodes, but this is nor persistent.

Here my cluster.conf

I would be glad, if someone could help me.

Greetings

Hansjörg
