I’m new to gluster administration, and am looking at a current gluster cluster… We have a 6 node gluster cluster and a volume called cdparchive2 that is set to distributed replicated. My assumption was that it is set to distribute across the first 3 bricks, and that group of 3 bricks would replicate to the next three bricks. Here is the output from gluster volume info cdparchive2 gluster volume info cdparchive2 Volume Name: cdparchive2 Type: Distributed-Replicate Volume ID: 1e3fdd58-14fc-459b-817f-6c6612090ecd Status: Started Number of Bricks: 3 x 2 = 6 Transport-type: tcp Bricks: Brick1: gluster07:/data/cdparchive2 Brick2: gluster08:/data/cdparchive2 Brick3: gluster09:/data/cdparchive2 Brick4: gluster10:/data/cdparchive2 Brick5: gluster11:/data/cdparchive2 Brick6: gluster12:/data/cdparchive2 So based on my assumptions/understanding, I thought it would distribute across nodes 7 8 and 9, and then replicate to 10, 11, 12. But when I login to each gluster data node and du a du –sm on /data/cdparchive2 I see the following: Nodes 7 and 8 are the same size, nodes 9 and 10 are the same size, and nodes 11 and 12 are the same size. So I guess that means its distributing to 7, 9 and 11, and replicating to 8, 10, and 12? Going forward, how do I create a new distributed replicated volume that acts the way I assume, that is distributes across first 3 nodes, and then replicates to the next 3 nodes? Would that be
gluster volume create test-volume replica 2 transport tcp gluster071:/test1 gluster08:/test2 gluster09:/test3 gluster10:/test4 gluster11:/test5 gluster12:/test6? |
