**介绍

glusterfs文件系统是：

1. 一个分布式可伸缩，最大可超过PB，可插拔的集群I / O调度器
2. 非停止性存储，非元数据存储
3. 可以通过mount挂载到本地，向本地磁盘一样读写
4. 简单易于管理

查看各个节点状态
gluster peer status

1.安装

1. 1 配置epel源

wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo

1.2 安装软件
yum install glusterfs glusterfs-server glusterfs-fuse

1. 3 添加hosts

[root@docker ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.1.1.134 docker
192.168.199.253 i2p.nginxs.net

1.4 注册并查看主机列表（不显示当前主机）

[root@cloud yum.repos.d]# gluster peer probe 192.168.199.222
peer probe: success.
[root@cloud yum.repos.d]# gluster peer status
Number of Peers: 1

Hostname: 192.168.199.222
Uuid: 67511194-333c-4919-88df-ccb5e10d9568
State: Peer in Cluster (Connected)
[root@cloud yum.repos.d]# gluster peer probe 192.168.199.8
peer probe: success. Probe on localhost not needed

1.5 创建逻辑卷

[root@cloud yum.repos.d]# gluster volume create dianjoygfs 192.168.199.{8,222}:/data1/gfs-data/
volume create: dianjoygfs: success: please start the volume to access data

1.6 启动存储逻辑卷

[root@docker ~]# gluster volume start dianjoygfs
volume start: dianjoytest: success

1.7 挂载glusterfs存储卷

[root@ntest1 ~]# mount.glusterfs 192.168.199.8:/dianjoygfs /mnt/gluster-mount/
[root@ntest1 ~]# df -hT
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda1 ext4 20G 8.8G 9.8G 48% /
tmpfs tmpfs 1.9G 16K 1.9G 1% /dev/shm
/dev/vdb1 ext4 50G 20G 28G 42% /data
192.168.199.8:/dianjoygfs
fuse.glusterfs 2.7T 861G 1.8T 33% /mnt/gluster-mount

这个存储卷的大小是，每个节点挂载“/data1/gfs-data/”的磁盘大小，其它信息同是如此。
