Hello, You cannot. As the message said, you cannot change the stripe count. So you can add 4 bricks and you have a distributed + striped volume, but you cannot change the stripe count by re-adding existing bricks into the volume with a different stripe count, or by adding an additional brick to the volume. Your email isn't very clear; could you please send: - the list of commands in the order that you typed them; - the output of "gluster volume info" and "gluster volume status" Thanks!
