partimage partition size

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,

I created a 20GB partition:

Model: SAMSUNG HD502HJ (scsi)
Disk /dev/sdb: 500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      32.3kB  20.0GB  20.0GB  primary  ext2
 2      20.0GB  40.0GB  20.0GB  primary  ext2

Then I restored with partimage a partition to /dev/sdb2 that was 
originally 13GB.

Now df shows that /dev/sdb2 is only 13GB:

debian:/var/cache/apt/archives# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb2             13456580   7654296   5118720  60% /
tmpfs                  1033084         0   1033084   0% /lib/init/rw
udev                     10240       824      9416   9% /dev
tmpfs                  1033084         0   1033084   0% /dev/shm
/dev/sdb1             19228276   3808488  14443040  21% /sdb1

How do I get that pack to 20GB?
