2016/08/06
 
Install GlusterFS to Configure Storage Cluster.
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.
[1] Install GlusterFS Server on all Nodes in Cluster.
[root@node01 ~]#
yum -y install centos-release-gluster38
[root@node01 ~]#
sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-Gluster-3.8.repo
# enable EPEL, too

[root@node01 ~]#
yum --enablerepo=centos-gluster38,epel -y install glusterfs-server
[root@node01 ~]#
systemctl start glusterd

[root@node01 ~]#
systemctl enable glusterd

[2] If Firewalld is running, allow GlusterFS service on all nodes.
[root@node01 ~]#
firewall-cmd --add-service=glusterfs --permanent

success
[root@node01 ~]#
firewall-cmd --reload

success
 
It's OK if you mount GlusterFS volumes from clients with GlusterFS Native Client.
[3] GlusterFS supports NFS (v3), so if you mount GlusterFS volumes from clients with NFS, Configure additinally like follows.
[root@node01 ~]#
yum -y install rpcbind
[root@node01 ~]#
systemctl start rpcbind

[root@node01 ~]#
systemctl enable rpcbind

[root@node01 ~]#
systemctl restart glusterd
# if Firewalld is running, allow services below

[root@node01 ~]#
firewall-cmd --add-service={nfs,rpc-bind} --permanent

[root@node01 ~]#
firewall-cmd --reload

Installing and Basic Settings of GlusterFS are OK. Refer to next section for settings of clustering.
