Hi Andreas,

	You are right and I am blind, the fail-over work now when the network 
failed, thank you very much !!

I just have to set now the "best" parameters for the ping monitor.

	With your help I just finish to migrate with the same "services" our 
test cluster from hearbeat(crm 1)/drbd (very easy to 
configure/migrate/manage/... used since more than 10 years, a bad news 
that this is obsolete) to corosync/pacemaker/drbd (Pffff..).

Best regards.

Francis
