Matt - 
A couple of questions - 

What is your volume config? (`gluster volume info all`) 
What is the hardware config for each storage server? 
What command did you run to create the test data? 
What process is still writing to the file?

I should also note that on this non-production test rig the block size 
on both bricks is 1KB (1024) so the theoretical file size limit is 
16GB. so how then did i get a file of 200GB?
