<p dir="ltr">Lets assume a 3 nodes cluster, replica 3, 6 1tb disks per node, 1 brick per disk.</p>
<p dir="ltr">i would like to increase space and thus add a new node.<br>
Can i add a single node with 3 disks/bricks and automatically rebalance?<br>
In this case, gluster moves data around to use the maximum number or disks for performance reasons?</p>
<p dir="ltr">We start with 18tb raw, 18 disks, 6tb usable, 100% used (6tb on 6 usable disks)<br>
After adding the new node with 3 disks we will end with 7tb usable.<br>
all disks would be used as 6tb/7=0.85% right? </p>
