I just ran into the same issue with an uc-3100 image.
Comparing the created filesystem with the source image using dumpe2fs shows different block sizes:

/tmp/original_mnt/p2
Block size: 1024

/tmp/resized_mnt/p2
Block size: 4096

Modifying create-img to specify a blocksize of 1024 for the mkfs command for the ext4 partitions fixes the issue for me:
mkfs -t ${fs_type} -b 1024 -J size=8 ${loopdev} >/dev/null 2>&1

Not sure if 1024 is an appropriate value for all different image types / systems so I'm not creating a pull request. Proper solution is more likely to query the parameters of the source partition to get the value from there, but maybe this info helps someone with the same issue.

This issue is fixed on my fork, didn't feel like making a PR just yet because I made a few other scripts for cleanup on the same branch. I've tested on 8200 devices and it works great, still need test on 8112 families.

# Get block size GH issue #6
o_loop=$(lsblk | grep original_mnt/p${i} | awk '{print $1}')
blocksize=$(dumpe2fs /dev/$o_loop | grep 'Block size' | awk '{print $3;}')

# Perform formation for different fs_type
#   vfat: format
#   ext4: format with journal
#   raw: do nothing
if [ "${fs_type}" == "ext4" ]; then
	mkfs -t ${fs_type} -b ${blocksize} -J size=8 ${loopdev} >/dev/null 2>&1
elif [ "${fs_type}" == "vfat" ]; then
	mkfs -t ${fs_type} ${loopdev} >/dev/null
fi
