GlusterFS是一個開源的分佈式文件系統,於2011年被紅帽收購.它具有高擴展性、高性能、高可用性、可橫向擴展的彈性特點,無元數據服務器設計使glusterfs沒有單點故障隱患，詳細介紹請查看官網：www.gluster.org 。
部署環境：
OS: CentOS release 6.5 (Final) x64
Server:
c1:192.168.242.132
c2:192.168.242.133
c3:192.168.242.134
c4:192.168.242.135
hosts：
192.168.242.132 c1
192.168.242.133 c2
192.168.242.134 c3
192.168.242.135 c4
具體操作：
c1/c2/c3/c4上執行
[root@c1 ~]# wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo
[root@c1 yum.repos.d]# yum install -y glusterfs glusterfs-server glusterfs-fuse
[root@c1 yum.repos.d]# /etc/init.d/glusterd start
Starting glusterd: [ OK ]
[root@c1 yum.repos.d]# chkconfig glusterd on
c1上配置集羣
[root@c1 ~]# gluster peer probe c1
peer probe: success. Probe on localhost not needed
[root@c1 ~]# gluster peer probe c2
peer probe: success.
[root@c1 ~]# gluster peer probe c3
peer probe: success.
[root@c1 ~]# gluster peer probe c4
peer probe: success.
如果c1在peer表中被識別爲ip地址，可能後面集羣過程中會出現通訊問題，
我們可以使用ip來進行修復:
[root@c3 ~]# gluster peer status
Number of Peers: 3
Hostname: 192.168.242.132
Uuid: 6e8d6880-ec36-4331-a806-2e8fb4fda7be
State: Peer in Cluster (Connected)
Hostname: c2
Uuid: 9a722f50-911e-4181-823d-572296640486
State: Peer in Cluster (Connected)
Hostname: c4
Uuid: 1ee3588a-8a16-47ff-ba59-c0285a2a95bd
State: Peer in Cluster (Connected)
[root@c3 ~]# gluster peer detach 192.168.242.132
peer detach: success
[root@c3 ~]# gluster peer probe c1
peer probe: success.
[root@c3 ~]# gluster peer status

刪除GlusterFS磁盤：
gluster volume stop datavolume1
gluster volume delete datavolume1
卸載GlusterFS磁盤：
gluster peer detach idc1-server4
訪問控制：
gluster volume set datavolume1 auth.allow 192.168.242.*,192.168.241.*
添加GlusterFS節點：
gluster peer probe c6
gluster peer probe c7
gluster volume add-brick datavolume1 c6:/usr/local/share/datavolume1 c7:/usr/local/share/datavolume1
遷移GlusterFS磁盤數據：
gluster volume remove-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 start
gluster volume remove-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 status
gluster volume remove-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 commit
數據重新分配：
gluster volume rebalance datavolume1 start
