Resources very quickly move on the slave node as expected. Then I return the binary on the master and restart the variator service. Now I make the same stuff with binary and service on slave node. The crm status command quickly shows me HA-variator   (lsb: variator):        Stopped. But it take to much time (for us) before recourses are switched on the master node (around 1 min).

Timeouts are all calculated locally. So it shouldn't be an issue (aside from trying to read the logs)
