It is created because you called "crm resource migrate" (which is a wrapper around crm_resource here). It is not "automatically created"; it's the way how the "migrate" command alters the configuration to enact the command you gave. You're telling pacemaker you want the resource moved away from a node. So that's what it does. > things but I did'nt find any solution. What should I do to prevent my > resource being automatically stopped ? Don't tell the cluster you want it to not be running on that node. It appears this is not what you actually want. If you'd explain what it is you're trying to achieve, maybe we can tell you how to do that?
