挂载点data
xenserver 10.0.3.223 10.0.3.224 ，在3.42 和3.43 服务器 上各添加一块盘

mkfs.xfs /dev/xvdi 
mkdir /data/data-ssp 
echo "/dev/xvdi /data/data-ssp xfs defaults 0 0 ">>/etc/fstab
mount -a

########安装服务###

yum install centos-release-gluster -y
yum -y install glusterfs-server glusterfs-fuse rpcbind 
systemctl start rpcbind
systemctl enable rpcbind
systemctl start glusterd
systemctl enable glusterd

######配置hosts
 

vim /etc/hosts
10.0.8.42    gfs3.ui.cm2    
10.0.8.43    gfs4.ui.cm2

######测试hosts是否成功，并添加节点

gluster peer probe gfs3.ui.cm2
gluster peer probe gfs4.ui.cm2

###如果删除，用下面命令

gluster peer detach node2

3.43上操作，建立一个gfs共享目录，会自动同步到3.42上

cd /data/data-ssp
mkdir ssp
gluster volume create GFS-data-ssp  replica 2 10.0.3.43:/data/data-ssp/ssp 10.0.3.42:/data/data-ssp/ssp
gluster volume start GFS-data-ssp 

客户端上操作

yum -y install glusterfs glusterfs-fuse
mount -t glusterfs 10.0.3.42:GFS-data-ssp /home/ads/ftp/ssp_bid
echo "10.0.3.42:GFS-data-hermers /tmp/hermers/signflag  glusterfs defaults 0 0" >> /etc/fstab
