change master导致gtid丢失
从innobackupex恢复导致binlog的拉取位置会导致主备gtid不一致。
此类错误通过构造空事务方式无法修复。
此时就需要change master 方式指向失败事件的下一个位点。然后按位点的方式(master_auto_position=0)来拉binlog。

当你观察你会发现Master服务器不再要求Slave服务器需要拉才能同步数据的二进制日志。可能的原因包括主服务器过期系统变量 expire_logs_days — — 通过二进制日志或有人手动从Master服务器通过清除二进制日志命令或 rm -f 命令删除二进制日志或者可能是你有一些 cronjob 的档案较旧的二进制日志，要求磁盘空间等。所以，请确保你总是有需要的二进制日志存在于主服务器上，您可以更新您的程序，以保持Slave服务器需要通过监测"Relay_master_log_file"变量Slave显示的Slave状态输出的二进制日志。此外，如果设置了 expire_log_days 在 my.cnf 老 binlogs 自动过期并移除。这意味着当 MySQL 打开一个新的 binlog 文件，它会检查旧的 binlogs，且清除任何早比 expire_logs_days 的值 （单位为天）。略服务器添加一个功能，过期日志基于而年龄的 binlog 文件不是使用的文件的总数量。所以在该配置中，如果你得到穗交通，它可能导致 binlogs 要比你预期的更早消失。详细信息请查看限制 binlog 文件的数目。
