My understanding is that this setting should stop new writes to a brick with less than 500GB of free space.  But that existing files might expand, which is why I went with a high number like 500GB.  But I am still getting full bricks, frequently it's the first brick in the cluster that suddenly fills up.

figure out, here's a general answer to your question about how the 
client chooses where to place a file:
