thanks a lot for the answer.
So, if you are correct, in a distributed with replica environment the best
practice is to pair nodes with the smallest size together?
node1 1 GB
node2 10 GB
node3 4 GB
node4 8 GB
node5 15 GB
node6 7 GB
node1 with node3 (smallest is 1 GB)
node4 with node6 (smallest is 7 GB)
node2 with node5 (smallest is 10 GB)
The command to launch:
gluster volume create gv0 replica 2 node1:/opt/data/gv0 node3:/opt/data/gv0
node4:/opt/data/gv0 node6:/opt/data/gv0 node2:/opt/data/gv0
Right? In this way I should have 18 GB of free space on the mounted volume
(1 GB + 7 GB + 10 GB)
