I'm driving some experiments on grid'5000 with GlusterFS 3.2 and, as a first point, i've been unable to start a volume featuring 128bricks (64 ok)<br>

<div><br></div><div>Also we are working on scalability of 'glusterd', the glusterfs management daemon, after which it should work fine. One work around for now is, create a volume with 64 bricks and do the 'add-brick' of another 64 brick. It should work fine.</div>

Then, due to the round-robin scheduler, as the number of nodes increase (every node is also a brick), the performance of an application on an individual node decrease!<br>
So my question is : how to STOP the round-robin distribution of files over the bricks within a volume ?<br></blockquote><div><br></div><div>There is no 'Scheduler' in picture here with GlusterFS 3.2.x (for that matter from 3.0.x releases), hence there is no option to stop the scheduler.</div>
