[ClusterLabs] pacemaker systemd resource

[Хиль Эдуард]

Hi Klaus! Thank you for your attention, but isn’t work. I have added Type=simple and there is no changes. I think problem not in service. As we can see from logs, the service is starting (Jul 21 15:53:42 node2.local dummy[9330]: hello world 1) but for the some reason pacemaker isn’t see it (Jul 21 15:53:42 node2.local pacemaker-controld[1813]:  error: Result of stop operation for dummy.service on node2.local: Timed Out ) and he draws his conclusions for 2 seconds (from 15:53:41 to 15:53:42) and i have no idea what to do :(
