Before resizing the filesystem by "resize2fs" command you should first resize your partition:

let's list block devices attached to our box:

lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 16G 0 disk

# To get better performance out of EFS, you may consider increasing the size of
# your filesystem by adding dummy data onto it. You can create dummy data using
# the command below to create a 256 GB file called "large_file":
sudo dd if=/dev/urandom of=large_file bs=1024k count=256000 status=progress

# A larger EFS fielsystem will result in a higher baseline throughput and you
# will be able to burst for longer periods. In the example above where we have
# an EFS with +256 GB, the baseline throughput will be 12.5 MiB/s and you can
# burst for 360 minutes per day as opposed to a 1GiB EFS which has a baseline
# of 50 KiB/s and can only burst for about 1 minute. However, the tradeoff

# create a large file to increase throughput for EFS bursting mode
dd if=/dev/urandom of=large_file bs=1024k count=256000 status=progress
