从easyops界面点击kfka实例——>broker——>查看brokerid的实例id=component_instance_id

连接easyops数据库执行SQL

select hostvars from easyops.component_instance_config where component_instance_id = 'xxx';

查出的数据类似如下，将查出的数据中需要添加数据盘信息添加，并写回到原纪录，注意修改后的数据确认可格式化为json

volumes后面添加数据盘，以逗号分隔

替换原有数据盘的SQL如下：

update easyops.component_instance_config set hostvars = 'xxx' where component_instance_id = 'xxx';

登录easyops所在的节点，进入easyops容器；

docker exec -it easyops-manager bash

cd services-spec/specs/

sh load_service.sh kafka

组件同步配置——>每个broker重启单独点击重启，登录到kafak broker所在的机器，到config目录下，查看下发后的配置文件server.properties 的参数log.dirs是否有多个数据目录
