kubernetes --- Glusterfs

gluster配额管理
gluster volume quota cloud enable
gluster volume quota cloud limit-usage /mail/pbs 20MB
dd if=/dev/zero of=test bs=1MB count=100

添加一个服务器加入到存储池中，前提是他们能被DNS服务器解析到。让你的防火墙能够通过probe requests/replies ：
gluster peer probe server
2.反向操作，删除一个服务器从存储池中。
gluster peer detach server4
