You could do this - where Node3 & Node 2 also has arbiter bricks. Arbiter bricks only store metadata and requires very low storage capacity compared to the data bricks.

Node1  Node2     Node3        Node4
brick1   brick1      arb-brick
            arb-brick  brick1        brick1

Ok, cool! And this won't pose any problem if Node2 or Node4 fail?

No.

The syntax shuld be this:

gluster volume create data replica 3 arbiter 1 node1:/brick node2:/brick node2:/arb_brick node3:/brick node4:/brick node4:/arb_brick

Correction: arb_bricks should be from a different node as below:
 
gluster volume create data replica 3 arbiter 1 node1:/brick node2:/brick node3:/arb_brick node3:/brick node4:/brick node2:/arb_brick



is not a problem having more than a brick on the same host for the volume create syntax?

Thanks again
