2.配置 GlusterFS 集群：
启动 glusterFS
systemctl start glusterd.service
systemctl enable glusterd.service
【k8s-glusterfs】3.将 节点 加入到 集群中。
gluster peer probe node1
gluster peer probe node2
gluster peer probe node3
4.三个节点创建卷
mkdir -p /opt/gluster/data
5.加入卷
gluster volume create models replica 3 node1:/opt/gluster/data node2:/opt/gluster/data node3:/opt/gluster/data force
6.启动
gluster volume start models
7.查看状态
gluster volume info
加载 1.安装客户端
yum install -y glusterfs glusterfs-fuse
2.挂载
mount -t glusterfs node1:models /root/disk#注意使用volume名称
3.卸载
umount /root/disk
log
tailf /var/log/glusterfs/root-disk.log
