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
