How to use GS_ Expansion expansion node

The current environment is 1 Lord 1 from , Want to add a slave node , Use gs_expansion super-popular , I don't know how to write a configuration file , Use the following configuration file to expand and report an error ：[[email protected] script]# ./gs_expansion -U omm -G dbgrp -X /tmp/cluster_config_template.xml -h 192.168.1.85Traceback (most recent call last): File "/soft/opengauss/script/gs_expansion", line 583, in expansion.getExpansionInfo() File "/soft/opengauss/script/gs_expansion", line 266, in getExpansionInfo self._getClusterInfoDict() File "/soft/opengauss/script/gs_expansion", line 198, in _getClusterInfoDict self.check_xml_config() File "/soft/opengauss/script/gs_expansion", line 406, in check_xml_config xml_cluster_info) File "/soft/opengauss/script/gs_expansion", line 570, in compare_cluster_info raise Exception("XML configuration failed, "Exception: XML configuration failed, node count in expantion XML must be more than static file. The contents of the configuration file are as follows :[[email protected] tmp]# more cluster_config_template.xml
