FCB::打开失败：无法打开文件

Question

当我收缩数据库时，机器重新启动，从那时起就SQL Server (MSSQLSERVER)没有启动。阅读博客后，我替换了master.mdf和 mastlog.ldf用相同的文件替换了模板文件夹中的

但是问题仍然存在，错误日志文件给出以下消息，

Starting up database 'msdb'.
Starting up database 'mssqlsystemresource'.
Error: 17204, Severity: 16, State: 1.
FCB::Open failed: Could not open file E:\sql12_main_t.obj.x86Release\sql\mkmastr\databases\mkmastr.proj\MSDBData.mdf for file number 1.  OS error: 3(The system cannot find the path specified.).

我可以明确地说我的机器上没有E:\分区。您能帮我修复我现在认为是错误的路径吗？

我不知道这是一个错误还是 SQL Server 2014 中常见的问题。\n对数据库的一些引用将保持如下所示：

\n\n

E:\\sql12_main_t.obj.x86Release\\sql\\mkmastr\\databases\\mkmastr.proj\\MSDBData.mdf\n

\n\n

所以你基本上必须直接在数据库中更改它们。

\n\n

以管理员身份运行 CMD 控制台并访问数据库，如下所示：

\n\n

SQLCMD -S .\\\n

\n\n

或者像这样，如果你有一个实例：

\n\n

SQLCMD \xe2\x80\x93S .\\INSTANCENAME\n

\n\n

使用以下句子将文件重命名为默认位置：

\n\n

ALTER DATABASE model MODIFY FILE ( NAME = modeldev, FILENAME = \'C:\\Program Files\\Microsoft SQL Server\\MSSQL12.MSSQLSERVER\\MSSQL\\DATA\\model.mdf\');\nALTER DATABASE model MODIFY FILE ( NAME = modellog, FILENAME = \'C:\\Program Files\\Microsoft SQL Server\\MSSQL12.MSSQLSERVER\\MSSQL\\DATA\\modellog.ldf\');\nALTER DATABASE msdb MODIFY FILE ( NAME = MSDBData, FILENAME = \'C:\\Program Files\\Microsoft SQL Server\\MSSQL12.MSSQLSERVER\\MSSQL\\DATA\\MSDBData.mdf\');\nALTER DATABASE msdb MODIFY FILE ( NAME = MSDBLog, FILENAME = \'C:\\Program Files\\Microsoft SQL Server\\MSSQL12.MSSQLSERVER\\MSSQL\\DATA\\MSDBLog.ldf\');\nALTER DATABASE tempdb MODIFY FILE ( NAME = tempdev, FILENAME = \'C:\\Program Files\\Microsoft SQL Server\\MSSQL12.MSSQLSERVER\\MSSQL\\DATA\\temp.mdf\');\nALTER DATABASE tempdb MODIFY FILE ( NAME = templog, FILENAME = \'C:\\Program Files\\Microsoft SQL Server\\MSSQL12.MSSQLSERVER\\MSSQL\\DATA\\temp.ldf\');\nGO\n

\n\n

之后，你的 sa 用户将保持没有密码（这发生在我身上，不确定是否总是发生），只需再次登录控制台并手动更改密码：

\n\n

ALTER LOGIN sa WITH PASSWORD = \'newpassword\' UNLOCK\n

\n\n

当我执行最后一步时，我遇到了问题，因为我的默认登录是使用 Windows 身份验证配置的，因此指令：

\n\n

SQLCMD -S .\\\n

\n\n

没用，只需添加 sa 用户，无需密码：

\n\n

SQLCMD -S .\\ -Usa\n

\n\n

希望能帮助到你。
