I set it to 0 but no difference. The problem was, after having re-set le transport-type to rdma,tcp some brick down after a few minutes.. Despite of restarting volumes, after a few minutes, some [other/different] bricks down again.</div><div><br></div><div>Now, after re-creation of my volume, bricks keep alive but, oddly, i’m not able to write on my volume. In addition, I defined a distributed volume with 2 servers, 4 bricks of 250GB each and my final volume seems to be only sized to 500GB… It’s amazing.. </div><div><br></div><div>Here you can find some information:</div><div><div style="margin: 0px;
