As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.</p>
<p dir="ltr">You can use the following for adding the bricks:</p>

<p dir="ltr">Gluster is quite smart, but in order to provide any hints , can you provide output of 'gluster volume info <glustervol>'.<br clear="none">
If you have 2 more systems , keep in mind that it is best to mirror the storage on the second replica (2 disks on 1 machine -> 2 disks on the new machine), while for the arbiter this is not neccessary.</p>
<p dir="ltr">What is your network and NICs ? Based on my experience , I can recommend at least 10 gbit/s interfase(s).</p>
