<br></div>So I'm thinking of helping this customer move the storage to gluster<br><br></div>They have limited budget, so buying new machine with big disk is not an option. But, they have a couple of old machine available, and the disk size differs in each of them<br>
<br></div>So, I'm planning to grow the storage slowly for them.<br><br></div>The first step that I think is to get 2 replicated storage nodes, so that redundancy can be increased.<br><br></div>Once that work, I'm planning to introduce another node to get a distributed-replicated system. This is the part that I'm not sure.<br>
<br></div>Let say the customer have nodes like this:<br></div>node1: 100GB (p1n1)<br></div>node2: 200GB (p1n2,p2n2)<br></div>node3: 300GB (p1n3)<br><br></div>node1 is currently the single BackupPC storage. I can partition node2 to get a 100GB (p1n2), then join with node1 (p1n1) to get a replicated gluster storage.<br>
<br></div>When I introduce node3 later, I plan to use the extra 100GB from node2 (p2n2), to join with 100GB from node3 (p1n3). Now, I have 4 bricks defined. 1 brick in node1 (p1n1), 2 brick in node2 (p1n2,p2n2), and 1 brick in node3 (p1n3).<br>
<br></div>The question is, how to change from replicated system (p1n1-p1n2), to distributed-replicated [(p1n1-p1n2)(p2n2-p1n3)] in a running system?<br><br></div>Ideas?<br><br>Thanks.<br><div><div><br><div><div><div><div>
