The script t3000-resize-fat.sh generates the same results for when I
use parted-1.9.0.
After some testing, it appears that parted does not like to resize
FAT32 file systems if they are smaller than 256MB.
By making the below posted changes to the script I was able to create
a FAT32 file system of about 256 MB in size (aligned to a cylinder),
and then successfully grow it by about 8MB (one cylinder).
Hope this helps :-)

Hmm...
I tried what you suggested, but it still doesn't work with 1.9.
[however, I did track down one bug: two changes that recently
moved from next to master modified FAT file system handling,
and one introduced a bug. I expect to revert them soon.]
Are you sure that your final resize succeeded?
If so, please show the actual commands you used
as well as before and after results of running this:
parted -s $dev u s p
(I tried with 1.9 built from source, and the 1.8.8 from Fedora 11 as
well as the one from debian unstable -- all with this same result)
Here are the commands I used:
dev=/dev/sde
parted -s $dev mklabel gpt
parted -s $dev mkpart primary fat32 63s 530144s
# if needed, wait for the partition device (e.g., /dev/sdd1) to appear
mkfs.vfat -F 32 ${dev}1
parted -s $dev resize 1 63s 546147s
That final parted invocation always fails with this:
No Implementation: GNU Parted cannot resize this partition to this size.
We're working on it!
Hi Jim,
I retried these steps on a virtual machine I built with Fedora 11. I
installed the latest parted git master branch and ran into a different
problem.
The testing below shows that that either:
a) parted does not recognize the FAT32 file system
or
b) the mkfs.vfat v3.0.1 command does not properly create the FAT32
file system.
