Yes in the end I rewrote the constrains as follows (with comments). <constraints> # CL_stonithset_node01 cannot run on wispoller1 <rsc_location id="node-1-dont-run" rsc="CL_stonithset_node01" node="wispoller1" score="-INFINITY"/> # CL_stonithset_node02 cannot run on wispoller2 <rsc_location id="node-2-dont-run" rsc="CL_stonithset_node02" node="wispoller2" score="-INFINITY"/> # CL_stonithset_node01 and CL_stonithset_node02 cannot run together <rsc_colocation id="stonith_not_same" rsc="CL_stonithset_node02" with-rsc="CL_stonithset_node01" score="-INFINITY"/> # resource group grp_1 has a preferred score of 100 on wispoller1 - which means if it is running the grp # should always failover to wispoller1 <rsc_location id="rsc_location_group_1" rsc="grp_1" node="wispoller1" score="100"/> </constraints> In addition I changed the options settings for the stonith resources and added clone-max to 1 for each resource. Also changed clone_node_max to clone-node-max on both as per literature - hopefully this is correct. clone-max is set to one because this is "How amny copies of the resource to start" in the cluster. For riloe there should only ever be one running and not on itself.
