[Gluster-users] Distributed-Replicated with mismatch number of bricks
Hi,
I would like to implement a distributed-replicated architecture but some
of my nodes have different number of bricks. My idea is to do a replica 2
through 6 nodes (all bricks with the same size).
My gluster architecture is:
Name node | Brick 1 | Brick 2
------------------------------------------
Node1 | R1 | |
Node2 | R1 | |
Node3 | R2 | R3 |
Node4 | R2 | R3 |
Node5 | R4 | R5 |
Node6 | R4 | R5 |
My questions are:
1. Would be this correct ?
gluster volume create vol0 replica 2 transport tcp \
node1:/data/gluster/vol0/brick1 node2:/data/gluster/vol0/brick1 \
node3:/data/gluster/vol0/brick1 node4:/data/gluster/vol0/brick1 \
node3:/data/gluster/vol0/brick2 node4:/data/gluster/vol0/brick2 \
node5:/data/gluster/vol0/brick1 node6:/data/gluster/vol0/brick1 \
node5:/data/gluster/vol0/brick2 node6:/data/gluster/vol0/brick2 \
2 If I need to add a new node in the future, I will be able to extend my
distributed replication system ? Something like:
Name node | Brick 1 | Brick 2
------------------------------------------
Node1 | R1 | |
Node2 | R2 | |
Node3 | R3 | R4 |
Node4 | R3 | R4 |
Node5 | R5 | R6 |
Node6 | R5 | R6 |
Node7 | R1 | R2 |
gluster volume create vol0 replica 2 transport tcp \
node1:/data/gluster/vol0/brick1 node7:/data/gluster/vol0/brick1 \
node2:/data/gluster/vol0/brick1 node7:/data/gluster/vol0/brick2 \
node3:/data/gluster/vol0/brick1 node4:/data/gluster/vol0/brick1 \
node3:/data/gluster/vol0/brick2 node4:/data/gluster/vol0/brick2 \
node5:/data/gluster/vol0/brick1 node6:/data/gluster/vol0/brick1 \
node5:/data/gluster/vol0/brick2 node6:/data/gluster/vol0/brick2 \
3. My nodes will also mount volumes (gluster clients) so in order to
optimize the read performance operations, what is the best replication
system: distributed-replicated or only replicated.
Thanks in advance.
