is it necessary to induce resource relocation by killing apache? I would use 'crm migrate resAPACHE' on the active node (for example). You must not forget to finish with 'crm unmigrate resAPACHE' at some point in your examples, otherwise 'resAPACHE' would not return to your formerly active node in any case ;) It is possible I think, but I am not that far yet. BTW: why do you use 'lsb:httpd' instead of 'ocf:heartbeat:apache' ? The pacemaker resource agent is much more reliable in a cluster structure. Killing 'resAPACHE' using the ocf agent produces migration-threshold (infinity) and fail-count (+1) scores which surely can be used to move the resource to another node. I, too, am still learning how that is achieved.
