2016/08/06
 
Configure Storage Clustering.
For example, create a Striping volume with 2 servers.
This example shows to use 2 servers but it's possible to use more than 3 servers.
                                  |
+----------------------+          |          +----------------------+
| [GlusterFS Server#1] |10.0.0.51 | 10.0.0.52| [GlusterFS Server#2] |
|   node01.srv.world   +----------+----------+   node02.srv.world   |
|                      |                     |                      |
+----------------------+                     +----------------------+

 
It is recommended to use partitions for GlusterFS volumes which are different from the / partition. The environment on this example is set as that sdb1 is mounted on /glusterfs directory for GlusterFS Configuration on all Nodes.

[2] Create a Directory for GlusterFS Volume on all Nodes.
[root@node01 ~]#
mkdir /glusterfs/striped

[3] Configure Clustering like follows on a node. (it's OK on any node)
# probe the node

[root@node01 ~]#
gluster peer probe node02

peer probe: success.
# show status

[root@node01 ~]#
gluster peer status

Number of Peers: 1

Hostname: node02
Uuid: 2ca22769-28a1-4204-9957-886579db2231
State: Peer in Cluster (Connected)

# create volume

[root@node01 ~]#
gluster volume create vol_striped stripe 2 transport tcp \
node01:/glusterfs/striped \
node02:/glusterfs/striped

volume create: vol_striped: success: please start the volume to access data
# start volume

[root@node01 ~]#
gluster volume start vol_striped

volume start: vol_replica: success
# show volume info

[root@node01 ~]#
gluster volume info

Bricks:
Brick1: node01:/glusterfs/striped
Brick2: node02:/glusterfs/striped
Options Reconfigured:
transport.address-family: inet
