[CentOS] can't create large LVM, even though pvscan shows enough space left

I'm trying to create a 500GB lv volume on a 500GB physical volume, but can't:

[root at francois-pc ~]# pvscan
  PV /dev/sdd                  VG freenas      lvm2 [500.00 GB / 500.00 GB free]
  PV /dev/sdc                  VG thecus       lvm2 [1010.00 GB /
910.00 GB free]
  PV /dev/mapper/ddf1_RAIDp2   VG VolGroup00   lvm2 [931.25 GB / 0    free]
  Total: 3 [2.38 TB] / in use: 3 [2.38 TB] / in no VG: 0 [0   ]
[root at francois-pc ~]# lvcreate -L 500gig -n 500G freenas
  Insufficient free extents (127999) in volume group freenas: 128000 required

Even dropping the size a bit, I get this:

[root at francois-pc ~]# lvcreate -L 500gig -n 450G freenas
  Insufficient free extents (127999) in volume group freenas: 128000 required



How do I actually create a 500GB volume?
