集群管理
获取集群信息
调用资源管理节点提供的API进行集群管理。curl命令中的IP和端口地址分别为资源管理节点配置文件中的ip和listen选项。
curl -v "http://192.168.2.160:15010/admin/getCluster" | python -m json.tool
展示集群基本信息，比如集群包含哪些数据节点和元数据节点，卷等。

冻结集群
命令行：
./udbto-cli cluster freeze true 冻结集群
Freeze cluster successful!
./udbto-cli cluster info 查看集群
[Cluster]
Cluster name : udbto01
Master leader : 192.168.0.121:15010
Auto allocate : Disabled 冻结状态
MetaNode count : 4
MetaNode used : 1 GB
MetaNode total : 11 GB
DataNode count : 4
DataNode used : 39 GB
DataNode total : 3849 GB
Volume count : 11
EbsAddr :
LoadFactor : 0
BatchCount : 0
MarkDeleteRate : 0
DeleteWorkerSleepMs: 0
AutoRepairRate : 0
MaxDpCntLimit : 0
./udbto-cli cluster freeze false 解除冻结
Unfreeze cluster successful!
Restful API:
curl -v "http://192.168.2.160:15010/cluster/freeze?enable=true"
enable 如果设置为true，则集群被冻结,false 表示解冻。
响应示例
{"code":0,"msg":"success","data":"set DisableAutoAllocate to true successfully"}
如果启用了冻结集群功能，卷就不再自动地创建数据分片，也不能手动创建分片。
获取集群空间信息
命令行：
./udbto-cli cluster stat

更新可用区状态
更新可用区的状态为可用或不可用。
设置为不可用
curl -v "http://192.168.2.160:15010/zone/update?name=default&enable=false"
enable true表示可用，false为不可用
响应示例
{"code":0,"msg":"success","data":"update zone status to [false] successfully"}
用命令行查看状态，已经变成不可用
./udbto-cli zone info default
Zone Name: default
