But I'm not sure how to make r3 start in that case. Perhaps something like this would do (or something similar): colocation no-r3 -inf: r3 r2 location no-r3-on-a r3 -inf: nodea location pref-r3 r3 50: nodeb > What attribute is set on Node A, that exactly tells me that the > resource is running ?

Normally, you use only RA created attributes, for instance by ping.
