我在Windows Server 2012上运行的MySQL实例出现问题。
有时数据库“自行关闭”。日志文件中提供的错误代码：
Windows日志：
InnoDB: File (unknown): 'flush' returned OS error 121. Cannot continue operation
MySQL日志：
Version: '5.6.22-log' socket: '' port: 3306 MySQL Community Server (GPL)
2017-03-23 04:30:04 147c InnoDB: Operating system error number 21 in a file operation.
InnoDB: Some operating system error numbers are described at
InnoDB: http://dev.mysql.com/doc/refman/5.6/en/operating-system-error-codes.html
2017-03-23 04:30:04 408 [ERROR] InnoDB: File (unknown): 'flush' returned OS error 121. Cannot continue operation
如果我再次启动MySQL服务，它会运行大约1天，然后错误返回服务停止，上面有错误。
任何想法错误的含义是什么？找不到有关此特定错误的Informatoin。
