Files created with dd either directly on the s3f3 mounted volume or copied to it are 0k in size

Files created with dd either directly on the s3f3 mounted volume or copied to 
it are 0k in size

When I attempt to create some dummy test data with either the fallocate or dd 
command on the s3fs mounted volume, the resulting file is 0k in size no matter 
what size I try to make it. 

If I create the file on a local partition using dd of fallocate, the file is 
created with the correct size. However, when I attempt to copy it to the s3fs 
mounted volume, the file size is 0k.

I am able to other local files from the system to the s3fs mounted volume and 
the size is reported correctly.
