3. 卸载某个节点GlusterFS磁盘
[root@swarm-manager ~]#gluster peer detach swarm-node-2
4. 设置访问限制,按照每个volume 来限制
[root@swarm-manager ~]#gluster volume set models auth.allow 10.6.0.*,10.7.0.*
5. 添加GlusterFS节点：
[root@swarm-manager ~]#gluster peer probe swarm-node-3
[root@swarm-manager ~]#gluster volume add-brick models swarm-node-3:/opt/gluster/data
注：如果是复制卷或者条带卷，则每次添加的Brick数必须是replica或者stripe的整数倍
6. 配置卷
[root@swarm-manager ~]# gluster volume set
7. 缩容volume:
先将数据迁移到其它可用的Brick，迁移结束后才将该Brick移除：
[root@swarm-manager ~]#gluster volume remove-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data start
在执行了start之后，可以使用status命令查看移除进度：
[root@swarm-manager ~]#gluster volume remove-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data status
不进行数据迁移，直接删除该Brick：
[root@swarm-manager ~]#gluster volume remove-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data commit
注意，如果是复制卷或者条带卷，则每次移除的Brick数��须是replica或者stripe的整数倍。
扩容：
gluster volume add-brick models swarm-node-2:/opt/gluster/data
8. 修复命令:
[root@swarm-manager ~]#gluster volume replace-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data commit -force
9. 迁移volume:
[root@swarm-manager ~]#gluster volume replace-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data start
pause 为暂停迁移
[root@swarm-manager ~]#gluster volume replace-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data pause
abort 为终止迁移
[root@swarm-manager ~]#gluster volume replace-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data abort
status 查看迁移状态
[root@swarm-manager ~]#gluster volume replace-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data status
迁移结束后使用commit 来生效
[root@swarm-manager ~]#gluster volume replace-brick models swarm-node-2:/opt/gluster/data swarm-node-3:/opt/gluster/data commit
10. 均衡volume:
[root@swarm-manager ~]#gluster volume models lay-outstart
[root@swarm-manager ~]#gluster volume models start
[root@swarm-manager ~]#gluster volume models startforce
[root@swarm-manager ~]#gluster volume models status
[root@swarm-manager ~]#gluster volume models stop
