Just wondering how Gluster determines which brick to send files to. I've got 4

It's setup in a replicating/distributing model.

Is there a way to 'weight' them? It would make sense for doing this on 
commodity hardware, as Gluster advertises - send less traffic to smaller 
bricks, and more to the bigger bricks.



Hi Andy,

Are you using the brick4 and brick4 from the same set of subvolume from the last time?. Since updating the replicate/distribute pairs you might need to run defrag.sh scripts to repopulate the hash values properly. Also this is the case when you don't defrag the older directories on old exports gets files written to their own set of pairs. Only new
      directories would help in creating files across evenly.
