        if (connection->fencing_policy >= FP_RESOURCE &&
            resource->role[NOW] != connection->peer_role[NOW]) {
                if (resource->role[NOW] == R_PRIMARY)
                        return OUTDATE_PEER_DISKS;
                if (connection->peer_role[NOW] != R_PRIMARY)           <--------- should be ¡°if (connection->peer_role[NOW] == R_PRIMARY)¡±
                        return OUTDATE_DISKS;
        }
        return OUTDATE_NOTHING;
