[Pacemaker] Service automatically restart after IP moving

[CHAMLEY Stephane]

Ah, Thanx you  ! :)

But it is not working ... : (
I did this test configuration (see below) and then I made a shift in the resouce IP (crm resource migrate).
Yet the process "ntp" is always the old date..

use an order constraint.

http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/s-resource-ordering.html

"If the first resource is (re)started while the then resource is running, the then resource will be stopped and restarted."

So if an ip is stopped and started somewhere else, the 'then' resource should restart.  is that what you were looking for?
