GlusterFS : Striping Setting2017/06/21

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 [/var/lib/glusterfs] directory for GlusterFS Configuration on all Nodes.
[1]	Install GlusterFS Server on All Nodes, refer to here.
[2]	Create a Directory for GlusterFS Volume on all Nodes.

root@node01:~#

mkdir -p /var/lib/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: a39156f3-32cb-451e-9e34-08ce504d72bb
State: Peer in Cluster (Connected)

# create volume

root@node01:~#

gluster volume create vol_striped stripe 2 transport tcp \
node01:/var/lib/glusterfs/striped \
node02:/var/lib/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

Options Reconfigured:
transport.address-family: inet

nfs.disable: on

[4]	If use NFS mount from Clients, Start required services first and also configure like follwos.
