服务端安装glusterfs yum install glusterfs
1.修改host文件，添加主机名对应IP （比如主机名分别是node1，node2，node3）
2.建立存储信任池
gluster peer probe node1 /
gluster peer probe node2
gluster peer probe node3
3.查看状态
gluster peer status
4.在存储节点上创建逻辑卷
lvcreate -L 1000G -T vg_bricks/brickspool
lvcreate -V 50G -T vg_bricks/brickspool -n brick1
mkfs.xfs -i size=512 /dev/vg_bricks/brick1
mkdir -p /bricks/brick1
vim /etc/fstab (添加自动挂载，default已经要添加_netdev,说明设备是网络设备，等待网络起来了自动挂载）
mount -a
mkdir /bricks/brick1/brick
5.创建distributed -replicated
gluster volume create firstvol relica 2
node1:/bricks/brick1/brick node2:/bricks/brick1/brick node3:/bricks/brick1/brick
gluster volume info firstvol
gluster volume start firstvol /启动卷
6客户端使用需要安装glusterfs-fuse
yum install glusterfs-fuse
mount -t glusterfs node1:/firstvol /mnt/vol
vim /etc/fstab
node:/firstvol /mnt/vol glusterfs defaults,_netdev 0 0
