When using the '-L' option in lvextend, you must enter the NEW size of the LV. In your command, you say you want to extend to LV to 500 MB. However, according to your lvdisplay, that LV is already at 4504 MB. Therefore, your command did not work.

If you want to extend the LV to 5000 MB, do:

# lvextend -L 5000 /dev/vgapp01/app1
