如果一个数据节点离线，TDengine集群将自动检测到。有如下两种情况：
- 该数据节点离线超过一定时间（taos.cfg里配置参数offlineThreshold控制时长)，系统将自动把该数据节点删除，产生系统报警信息，触发负载均衡流程。如果该被删除的数据节点重现上线时，它将无法加入集群，需要系统管理员重新将其添加进集群才会开始工作。
- 该数据节点离线超过一定时间（taos.cfg里配置参数offlineThreshold控制时长)，系统将自动把该数据节点删除，产生系统报警信息，触发负载均衡流程。如果该被删除的数据节点重新上线时，它将无法加入集群，需要系统管理员重新将其添加进集群才会开始工作。
- 离线后，在offlineThreshold的时长内重新上线，系统将自动启动数据恢复流程，等数据完全恢复后，该节点将开始正常工作。
**注意：**如果一个虚拟节点组（包括mnode组）里所归属的每个数据节点都处于离线或unsynced状态，必须等该虚拟节点组里的所有数据节点都上线、都能交换状态信息后，才能选出Master，该虚拟节点组才能对外提供服务。比如整个集群有3个数据节点，副本数为3，如果3个数据节点都宕机，然后2个数据节点重启，是无法工作的，只有等3个数据节点都重启成功，才能对外服务。

# 常见问题
## 0. 怎么报告问题？
如果 FAQ 中的信息不能够帮到您，需要 TDengine 技术团队的技术支持与协助，请将以下两个目录中内容打包：
1. /var/log/taos （如果没有修改过默认路径）
2. /etc/taos
附上必要的问题描述，包括使用的 TDengine 版本信息、平台环境信息、发生该问题的执行操作、出现问题的表征及大概的时间，在<a href='https://github.com/taosdata/TDengine'> GitHub</a>提交Issue。
为了保证有足够的debug信息，如果问题能够重复，请修改/etc/taos/taos.cfg文件，最后面添加一行“debugFlag 135"(不带引号本身），然后重启taosd, 重复问题，然后再递交。也可以通过如下SQL语句，临时设置taosd的日志级别。
```
alter dnode <dnode_id> debugFlag 135;
```
但系统正常运行时，请一定将debugFlag设置为131，否则会产生大量的日志信息，降低系统效率。
## 1. TDengine2.0之前的版本升级到2.0及以上的版本应该注意什么？☆☆☆
2.0版本在之前版本的基础上，进行了完全的重构，配置文件和数据文件是不兼容的。在升级之前务必进行如下操作：

- 2.0.7.0 及以后的版本，到/var/lib/taos/dnode下，修复dnodeEps.json的dnodeId对应的FQDN，重启。确保机器内所有机器的此文件是完全相同的。
- 1.x 和 2.x 版本的存储结构不兼容，需要使用迁移工具或者自己开发应用导出导入数据。
## 17. 怎么报告问题？
## 17. TDengine 是否支持删除或更新已经写入的数据？
如果 FAQ 中的信息不能够帮到您，需要 TDengine 技术团队的技术支持与协助，请将以下两个目录中内容打包：
1. /var/log/taos
2. /etc/taos
TDengine 目前尚不支持删除功能，未来根据用户需求可能会支持。

从 2.0.8.0 开始，TDengine 支持更新已经写入数据的功能。使用更新功能需要在创建数据库时使用 UPDATE 1 参数，之后可以使用 INSERT INTO 命令更新已经写入的相同时间戳数据。UPDATE 参数不支持 ALTER DATABASE 命令修改。没有使用 UPDATE 1 参数创建的数据库，写入相同时间戳的数据不会修改之前的数据，也不会报错。
