mysql slave replication doesn't work due to error 1236

My mysql master server has crashed due to storage issue. The issue has been fixed and the master is up and running. However, my slave has stopped to be replicated due to the error: Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'

Here is my slave status:

    mysql> show slave status\G;

And here is my master status:

mysql> show master status\G;
*************************** 1. row ***************************
            File: mysql-bin.000323
        Position: 103145634
    Binlog_Do_DB: 
Binlog_Ignore_DB: 
1 row in set (0.00 sec)

I can see that the specific binary log (mysql-bin.000321) doesn't exist on the master. The the log file itself exist on the server, but ain't shown by SHOW BINARY LOGS;.

mysql> SHOW BINARY LOGS;
