Trying Parted
I tried Parted first, as this is what the LVM-HOWTO[1] says to do, but I kept getting the following error, which lead me to google and to troubleshooters.com[2] ....

NOTE: I converted from ext3 to ext2 at this point to try and fix the Parted error
Trying Resize2fs
Running resize2fs with just the device shows the total blocks, so ...
root@1[~]# resize2fs /dev/hda1 resize2fs 1.38 (30-Jun-2005) The filesystem is already 19183610 blocks long. Nothing to do!
I can just take 10000000 blocks off ....
root@1[~]# resize2fs /dev/hda1 9183610 resize2fs 1.38 (30-Jun-2005) Please run 'e2fsck -f /dev/hda1' first.
Oh no !!!, Needs an FSCK first.
e2fsck First !
I ran e2fsck (-f for force checking even if the drive is marked clean)
root@1[~]# e2fsck -f /dev/hda1 e2fsck 1.38 (30-Jun-2005) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /: 26574/19202048 files (0.1% non-contiguous), 690651/19183610 blocks
Retry Parted
Maybe the problem was the unclean filesystem, since I converted from ext3 to ext2 before I did this.

Guess not.
Back to resize2fs
This took a while to run, approx 15 minutes (about as long as the e2fsck).
root@1[~]# resize2fs /dev/hda1 9183610 resize2fs 1.38 (30-Jun-2005) Resizing the filesystem on /dev/hda1 to 9183610 (4k) blocks. The filesystem on /dev/hda1 is now 9183610 blocks long.
A quick "sync" (since I was running knoppix) and then a shutdown -h now (to remove the CDROM drive)
After Picture
and after a reboot
debian:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/hda1 34G 350M 33G 2% / tmpfs 237M 0 237M 0% /dev/shm
