Hi Andreas,

thanks for your answer,

crm_simulate -s -L (node2 is offline - r_postfix is running on node1)

native_color: r_haproxy allocation score on node1: -INFINITY
native_color: r_haproxy allocation score on node2: -INFINITY

crm_simulate -s -L (both nodes are online - r_postfix is running on node1)

native_color: r_haproxy allocation score on node1: -INFINITY
native_color: r_haproxy allocation score on node2: 0

with 2 colocation and we see that colocation with score 100 is not setting

colocation cl_r_haproxy_not_on_r_postfix -inf: r_haproxy r_postfix
colocation cl_r_haproxy_on_r_postfix 100: r_haproxy r_postfix

I don´t understand because score on node2 is 0

Regards,

Wolfgang

-INF == never-ever ;-)

Hard to say without seeing the rest of your configuration, but you can
run "crm_simulate -s -L" to see all the scores taken into account.

Andreas
