Hi,

I just want to let you know that the problem is solved. Thanks to "crm_mon
-f". ;)
The error was the usage of the pingd RA. This RA worked very unreliable and
is marked as deprecated though (
http://comments.gmane.org/gmane.linux.highavailability.user/32290).
So after changing the RA to ocf:pacemaker:ping the pingd attribute was set
as expected and the location contraints are working as planned.

Here are the contraints for everybody who wants to implement an assimilable
behaviour:
primitive resPing ocf:pacemaker:ping \
        params host_list="standard-gateway node1 node2" multiplier="1000" \
        op monitor interval="5" timeout="60" \
        op start interval="0" timeout="60" \
        op stop interval="0" timeout="20"
location locDRBD0Node1 msDRBD0 \
        rule $id="locDRBD0Node1-rule" $role="Master" inf: #uname eq node1
location locDRBD0PingErr msDRBD0 \
        rule $id="locDRBD0PingErr-rule" $role="Master" -inf: not_defined
pingd or pingd number:lte 1000
location locDRBD1Node2 msDRBD1 \
        rule $id="locDRBD1Node2-rule" $role="Master" inf: #uname eq node2
location locDRBD1PingErr msDRBD1 \
        rule $id="locDRBD1PingErr-rule" $role="Master" -inf: not_defined
pingd or pingd number:lte 1000
location locIP0Node1 resIP0 \
        rule $id="locIP0Node1-rule" inf: #uname eq node1
location locIP0PingErr resIP0 \
        rule $id="locIP0PingErr-rule" -inf: not_defined pingd or pingd
number:lte 1000
location locIP1Node2 resIP1 \
        rule $id="locIP1Node2-rule" inf: #uname eq node2
location locIP1PingErr resIP1 \
        rule $id="locIP1PingErr-rule" -inf: not_defined pingd or pingd
number:lte 1000

"crm_mon -f" output:
... many resources
Migration summary:
* Node node1:  pingd=3000
* Node node2:  pingd=3000
