You should use an opt out cluster. Set the cluster option
symmetrical=false. This will tell corosync not to place a resource
anywhere on the cluster, unless a location rule explicitly tell the
cluster where it should run.
Corosync will still monitor sql resources on www hosts and return rc 5
but this is expected and works.

I set the infinity for pgsql on all 3 sql nodes, but not! on the
www nodes. Why tries Pacemaker to start the Postgres SQL Server on
the www Node? In example?
Thank for your Help
greetings
Hauke

Hello Alexandre,
Why can't i set the infinity for the SQL servernodes to start the SQL
Daemon only on the sql-nodes? I thought that has to be all?
http://clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/s-resource-location.html
Greetings
Hauke
You are right.
The Page says score: Values of +/- |INFINITY| change "can" to "must".
I have set location loc_sql_srv_node1 res_pgsql inf: sql-node1. But not
to www-node1. So i am wondering.
Greetings
