This looks like an asymetric cluster (there's an option for
that, find it in the output of crm ra info pengine). In that
case you add positive location constraints for all nodes which
you want the resource to run on. You can specify several nodes
like this:

location ... 100: #uname eq node1 or #uname eq node2 ...

Thanks,
