论坛大佬们好，想请教一根问题，mysql主从遇到了一个报错 errno:1594 报错内容是：Last_SQL_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master’s binary log is corrupted (you can check this by running ‘mysqlbinlog’ on the binary log), the slave’s relay log is corrupted (you can check this by running ‘mysqlbinlog’ on the relay log), a network problem, or a bug in the master’s or slave’s MySQL code. If you want to check the master’s binary log or slave’s relay log, you will be able to know their names by issuing ‘SHOW SLAVE STATUS’ on this slave

网上的办法是重建binlog_file 和master_log_pos, 如果这样操作的话，备库备份的数据和主库的数据还一致么，是不是会缺少pos值之前的数据呢？
还是mysql会自动将前面缺少的内容通过binlog来补齐呢？
