		+	'''Install GlusterFS Server And Client On CentOS 7'''
		+
		+	GlusterFS aggregates various storage servers over Ethernet or Infiniband RDMA interconnect into one large parallel network file system. It is free software, with some parts licensed under the GNU General Public License(GPL) v3 while others are dual licensed under either GPL v2 or the Lesser General Public License (LGPL) v3. GlusterFS is based on a stackable user space design.
		+
		+	GlusterFS has a client and server component. Servers are typically deployed as storage bricks, with each server running a glusterfsd daemon to export a local file system as a volume. The glusterfs client process, which connects to servers with a custom protocol over TCP/IP, InfiniBand or Sockets Direct Protocol, creates composite virtual volumes from multiple remote servers using stackable translators. By default, files are stored whole, but striping of files across multiple remote volumes is also supported. The final volume may then be mounted by the client host using its own native protocol via the FUSE mechanism, using NFS v3 protocol using a built-in server translator, or accessed via gfapi client library. Native-protocol mounts may then be re-exported e.g. via the kernel NFSv4 server, SAMBA, or the object-based OpenStack Storage (Swift) protocol using the “UFO” (Unified File and Object) translator.
		+
		+	I am using 2 CentOS 7 nodes with hostnames: glusterfs1 and glusterfs2.
		+
		+	Add this to both servers in /etc/hosts
		+	192.168.254.133 glusterfs1
		+	192.168.254.134 glusterfs2
		+
		+	Installing in CentOS:
		+	wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo
		+	yum -y install glusterfs glusterfs-fuse glusterfs-server
		+	systemctl start glusterd
		+
		+	Add iptable rules for glusterfs:
		+	-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.254.0/24 --dport 111 -j ACCEPT
		+	-A INPUT -m state --state NEW -m udp -p udp -s 192.168.254.0/24 --dport 111 -j ACCEPT
		+	-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.254.0/24 --dport 2049 -j ACCEPT
		+	-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.254.0/24 --dport 24007 -j ACCEPT
		+	-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.254.0/24 --dport 38465:38469 -j ACCEPT
		+	-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.254.0/24 --dport 49152 -j ACCEPT
		+
		+	Added glusterfs2 in glusterfs1’s hosts file, and tested the config:
		+	[root@glusterfs1 ~]# gluster peer probe glusterfs2
		+	peer probe: success.
		+
		+	[root@glusterfs2 ~]# gluster peer probe glusterfs1
		+	peer probe: success. Host glusterfs1 port 24007 already in peer list
		+
		+	At this time I can test the storage pool:
		+	[root@glusterfs1 glusterfs]# gluster pool list
		+	UUID Hostname State
		+	4cf47688-74ba-4c5b-bf3f-3270bb9a4871 glusterfs2 Connected
		+	a3ce0329-35d8-4774-a061-148a735657c4 localhost Connected
		+
		+	[root@glusterfs1 ~]# gluster volume status
		+	No volumes present
		+
		+	Create a gluster volume and test replication:
		+	[root@glusterfs1 ~]# gluster
		+	gluster> volume create vol0 rep 2 transport tcp glusterfs1:/data/gluster/brick glusterfs2:/data/gluster/brick force
		+	volume create: vol0: success: please start the volume to access data
		+	gluster>
		+
		+	###### if vol creation fails for some reason, do # setfattr -x trusted.glusterfs.volume-id /data/gluster/brick and restart glusterd.
		+
		+	gluster> volume start vol0
		+	volume start: vol0: success
		+
		+	Create mount point and mount the volume on both nodes:
		+
		+	[root@glusterfs1 ~]# mount -t glusterfs glusterfs1:/vol0 /mnt/gluster/
		+
		+	[root@glusterfs2 ~]# mount -t glusterfs glusterfs1:/vol0 /mnt/gluster/
		+
		+	[root@glusterfs1 ~]# cp /var/log/secure /mnt/gluster/
		+
		+	The content is automatically synced between nodes
		+
		+	[root@glusterfs1 ~]# ls /mnt/gluster/
		+	secure
		+
		+	[root@glusterfs2 ~]# ls /mnt/gluster/
		+	secure
