Resized ext3 partition, but filesystem remains the same

[Dell Sanders]

Hi,

Last night, I tried to resize my 2.5 GB ext3 linux
root partition to include an extra 2 GB of
unpartitioned disk space directly after /dev/hda3.
Unfortunately, I didn't RTFM properly and ran parted
while /dev/hda3 was mounted as root. I issued the
following commands - 

=======================================================
(parted) resize 3 4690.854 9193.447

(parted) print
Disk geometry for /dev/hda: 0.000-19077.187 megabytes

With fdisk, I see -

Partition table entries are not in disk order
=======================================================

df -h shows me the following -
=======================================================

/media/floppy0
/dev/hda7             2.8G  1.4G  1.5G  50% /mnt/fat32
=======================================================

It seems to me that the partition /dev/hda3 has been
resized to 4.5 GB, but the filesystem remains
restricted to 2.0 GB. Apart from that, the system runs
fine.

How can I grow my ext3 filesystem to fit the entire
/dev/hda3?
