Partition of 189GB gives with df 19 GB.

[Pascal Huisman <pascal@deception.nl>]

I made a partition on a new disk, sda1 with size of approx. 189 Gig.

But when I use df the size reported back, is 20 GB.

What I did which led to this is: 
With partimage I  copied  a image  from a different hdd (size 20GB) to a
bigger disk with a partition size of 189 GB.

After bootup it complained a bit and I was able to fix it with fsck
manually.
Everything seems to be alright, but I can't get past the 20 GB barrier
somehow.

How can I fix this next problem?

Thx.

Pascal.
