First of all you must use fencing for a dual-primary setup ... as you
have no fencing configured in Pacemaker I conclude (please correct me if
I'm wrong) that you also skip this part in DRBD config.

Then please share the result of "drbdadm dump all" and "cat /proc/drbd"
when your cluster is up. You said you see a "fresh" resync ... you mean
a full resync? Please also provide kernel logs for this.

Regards,
Andreas
