http://www.farnell.com/datasheets/2162038.pdf page 4 shows Ids vs Vgs plot that conduction start well above 2.5V (listed as Vgs(th) in the datasheet), so the the voltage put out by the GPIO pin, which should be almost 3.3V, should be enough. Do you have a multimeter to measure the actual gate voltage?
