[1] Configure the same settings on 4 GlusterFS servers like follows. It is recommended to create a directory for GlusterFS volume on the different partition from the / partition.
root@gfs01:~#
apt-get -y install glusterfs-server
root@gfs01:~#
vi /etc/hosts
# add GlusterFS servers

10.0.0.60       gfs01.srv.world gfs01
10.0.0.61       gfs02.srv.world gfs02
10.0.0.62       gfs03.srv.world gfs03
10.0.0.63       gfs04.srv.world gfs04

# create a directory for GlusterFS volume

root@gfs01:~#
mkdir /glusterfs/strip-replica

[2] Work on a server like follows.
root@gfs01:~#
gluster peer probe gfs02
# search the server

peer probe: success
# just found

root@gfs01:~#
gluster peer probe gfs03
# search the server

peer probe: success
# just found

root@gfs01:~#
gluster peer probe gfs04
# search the server

peer probe: success
# just found

root@gfs01:~#
gluster peer status
# show status

[3] Configure GlusterFS Clients to use GlusterFS volume from GlusterFS servers.
root@gfsclient:~#
apt-get -y install glusterfs-client
# mount the volume on /mnt

root@gfsclient:~#
mount -t glusterfs gfs01.srv.world:/vol_strip-replica /mnt
# just mounted

root@gfsclient:~#
df -h
