Dear users, I just started my first Gluster test volume using 3 servers (each server contains 12 hdd). I would like to create a "distributed disperse volume” but I’m a little bit confused about the right configuration schema that I should use. Should I use JBOD disks? How many bricks to be defined? Ideal redundancy value? Ideal disperse-data count value? 6x(4+2) or 3x(8+4) volume configuration? Which one is the best one and why? I’m trying to refer to the admin guides that I have found on internet but, in my case, it’s very difficult understand details because of some missing information. Do you have some useful suggestions about the right configuration to be selected in order to reach an optimal fault tolerance and performance level? This is my first test configuration (see the gluster volume info command output below), what do you think about it? I created it using gdeploy and I used all the bricks, is it ok? Or should I use only part of them and in a specific order?
