my mainboard is MSI RS480 M2

CPU AMD 64 3000+
HDD Segate 20G IDE
Maxtor 160G SATA x 2
My mainboard have silicon image SATA Raid controller building.
Then I compile kernel 2.6.11 and enable data-mapper module.
And I create Maxtor 160G x 2 to raid 0 .
[root@ares ~]# dmraid -s
*** Active Set
name : sil_afaeafbgccbgb
size : 640339968
stride : 64
type : striped
status : ok
subsets: 0

[root@ares ~]# sfdisk --show-size /dev/mapper/sil_afaeafbgccbgb
320169984
[root@ares ~]# sfdisk --show-size /dev/mapper/sil_afaeafbgccbgb1
320167386
Every thing seem to be OK, but when I mount /dev/mapper/sil_afaeafbgccbgb1
and use command df.
[root@ares ~]# df

Why the system show a half size (160074724 ) of my raid array.
