As said I've added it in /etc/drbd.d/global_common.conf which is now

     $ cat global_common.conf
     global {
             usage-count no;
             disable-ip-verification;
      }
     common {
     handlers {
         fence-peer "/usr/lib/drbd/crm-fence-peer.sh";
         after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh";
       }
	     syncer { rate 500M; }
}

but no improvment.
