Subject: [Gluster-users] 2 nodes replication upgrade to 4 nodes<br>

<div>I am wondering about almost the exact same thing. I don' know about the add-brick. I know manual the notes when you list s1,s2,s3,s4 in the create volume command it will distribute across s1 and s2 then replicate to s3 and s4. This is the layout I want
but currently s1 is replicated to s2. So what would happen in the process of switching s1 and s2 from rep to dist.
<div><br>
</div>
<div>Maybe replace brick s2 with s3 and then add brick s2 and s4? Followed but a rebalence. </div>

<div style="direction:ltr">We are building a storage that will start as 2 servers in replica mode,</div>
<div style="direction:ltr">I was just wondering if its possible to add another replica set to that volume later and by that make it distributed?</div>
<div style="direction:ltr">let say we have server1 & server2 as replica set 1 by running:</div>
<div style="direction:ltr">gluster volume create test-volume replica 2 transport tcp server1:/exp1 server2:/exp2</div>
<div style="direction:ltr">then later on will need to add server3 & server4 as replica set2, so i guess my questune is if at this point we run:</div>
