我们的设置：

• 大师：MariaDB 10.0.21
• 奴隶：MariaDB 10.0.17

直到最近，复制工作正常，此时必须从转储中恢复从属数据库。我执行了所有必要的步骤：转储主数据库，将转储传输到从数据库，删除旧数据库，执行转储以恢复数据库，执行适当的CHANGE MASTER命令，最后START SLAVE.

我收到错误： Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'

从站需要从主站获取的第一个日志文件是mysql-bin.000289. 我可以看到这存在于主人身上：

我还可以看到 master 上的二进制日志索引似乎有这个日志文件的条目：

仍然无法复制 - 我不断收到同样的错误。我没有想法 - 接下来我应该检查什么？

更新：SHOW SLAVE STATUS\G按要求输出：
