我在我的一个客户系统中面临这个问题。当我们通过SSMS连接到SQLServer2008DB引擎时，我发现了错误

无法打开数据库“msdb”，因为无法访问文件或内存或磁盘空间不足。有关详细信息，请参阅SQL Server错误日志细节。（Microsoft SQL Server，错误：945）

然后还连接到数据库。但是客户端数据库不可见。如果我试图再次扩展“系统数据库”或“安全性”或“管理”，则会出现此错误

硬盘有80 gb可用空间，帐户有权限，.mdf和.ldf文件不是只读的

在SQL Server配置管理器->SQL Server属性->登录身份->选择“此帐户”，并使用帐户名“admin”及其密码

他们能够通过来自其他PC的应用程序进行数据操作。问题仅限于从SSM访问

在错误日志中，我们可以看到

2016-08-10 18:02:56.17 spid13s     Error: 824, Severity: 24, State: 2.
2016-08-10 18:02:56.17 spid13s     SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x2411d175; actual: 0x2411dfd1). It occurred during a read of page (2:0) in database ID 4 at offset 0000000000000000 in file 'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\MSDBLog.ldf'.  Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

请建议我如何更正此问题，因为我的msdb文件已损坏且没有系统数据库备份，我必须重建msdb数据库，幸运的是没有作业或警报等。。。。我尝试了以下链接中的步骤

执行计划中只有一项更改是在从instmsb.sql重建MSDB的第6步。由于发生错误，我在命令提示符下停止了SQL Server服务，并从Configuration Manager启动。然后打开SSMS，连接到DB引擎（我得到一个错误，为此单击ok），然后从打开instmdb.sql C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Install\instmdb.SQL并执行
