语法：
gcadmin rmnodes gcChangeInfo.xml
gcChangeInfo.xml: 要删除的数据节点信息文件。
功能：
将gcChangeInfo.xml中指定数据节点从集群中移除。
注：要删除的数据节点必须是已添加到当前集群中的数据节点，并且是未被任何distribution使用的节点。
gcChangeInfo.xml为要移除的数据节点信息，如下所示

示例：
执行rmnodes命令将节点从集群移除
| $ gcadmin rmnodes gcChangeInfo.xml gcadmin remove nodes ...
node [192.168.153.126] had been removed node [192.168.153.130] had been removed node [192.168.88.137] had been removed
gcadmin rmnodes success |
