   <!-- Answer -->
   在 HugeGraph 1.5.0 + HStore 分布式环境下,数据不同步常见原因主要有以下几类:
   
   1. **配置不一致**:PD 和 Store 节点的 initial-store-list、raft peers-list、端口、IP 
必须完全一致,且所有节点网络互通,否则分区分配和 raft 
协议会异常,导致数据不同步。[详细说明](https://github.com/apache/incubator-hugegraph/issues/2716)
   2. **分区未分配**:1.5.0 版本不会在服务启动或 schema/graph 创建时自动分配分区,必须等所有 PD/Store 
节点注册、raft 选主完成后,由内部任务或手动 API 触发分区分配。可通过 PD 的 REST API `/partition/dispatch` 
手动分配分区,具体接口和参数见[这里](https://github.com/apache/incubator-hugegraph/issues/2821)。
   3. **PD/Store 节点异常**:如 PD 节点因内存不足被 kill、网络不通,或 raft 选主失败,会导致 schema 
获取、任务调度失败,进而出现数据不同步或部分节点无数据的情况。[相关案例](https://github.com/apache/incubator-hugegraph/issues/2837)
   4. **遗留配置干扰**:HStore+PD 场景下,`server.role` 等 master/worker 
配置已废弃,保留会导致调度器类型冲突(如 
ClassCastException),虽然不影响核心存储,但会导致定时任务、系统级调度失效,建议彻底移除。[官方说明](https://github.com/apache/incubator-hugegraph/issues/2841)
   5. **认证 schema 未初始化**:如果启用了认证,HStore 后端不会自动初始化 `~user` 顶点类型,需手动用 REST API 
创建相关 
schema,否则会导致初始化或后续操作异常。[解决方法](https://github.com/apache/incubator-hugegraph/issues/2844)
   
   建议排查步骤:
   - 检查所有 PD/Store 节点配置,确保 raft peers-list、initial-store-list、端口、IP 完全一致。
   - 查看 PD 和 Store 日志,确认没有分区分配失败、raft 选主异常、注册超时等报错。
   - 检查分区分配状态(可通过 PD 的 REST API 查询),如未分配可手动触发。
   - 移除所有 server.role、server.id 等遗留配置,确保完全由 PD 管理集群角色和调度。
   - 如启用认证,先手动补齐 `~user` schema,再初始化 store。
   - 如仍有问题,建议补充具体“不同步”表现(如哪些节点缺数据、查询结果不一致等)和相关日志片段,便于进一步定位。
   
   如需手动分配分区,可用如下 API:
   ```http
   POST http://<pd_host>:<pd_port>/partition/dispatch
   Content-Type: application/json
   
   {
     "graphName": "your_graph_name",
     "partitionCount": 12,
     "replicaCount": 1
   }
   ```
   分配前请确保所有 Store 节点已注册且 raft 选主完成。
   
   参考上述排查,绝大多数分布式数据不同步问题都能定位和解决。
