FCB ::打開失敗：無法打開文件

Question

機器在我縮小數據庫的同時重新啓動，此後SQL Server (MSSQLSERVER)未啓動。在閱讀博客之後，我使用相同的文件替換了模板文件夾中的master.mdf和mastlog.ldf文件，假設主數據庫已損壞，因爲我正在縮小此文件。

但是問題仍然存在，該錯誤日誌文件提供了以下信息，

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.).

我可以明確地說，有我的機器上沒有E:\分區。你能幫我修好我認爲現在是錯誤的道路嗎？

它可能是Windows相關的問題，它沒有適當的權限。請看一看就在這裏：http://blog.sqlauthority.com/2016/06/27/sql-server-fcbopen-failed-not-open-file-file-number-2-os-error-5access-denied/

Answer 2

我不知道這是否是平常不同的SQL Server 2014 一些引用到數據庫中的錯誤什麼的，會保持這樣的：

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

所以你基本上不得不直接在數據庫中改變它們。

運行CMD控制檯以管理員身份和訪問數據庫，如：

SQLCMD -S .\ 

或者像這樣的情況下，你有一個實例：

SQLCMD –S .\INSTANCENAME 

重命名文件的默認位置。這些句子：

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

之後，你的sa用戶將保持沒有passwo RD（它發生在我身上，不知道它總是會發生的），只需重新登錄到控制檯，並改變手動密碼：

ALTER LOGIN sa WITH PASSWORD = 'newpassword' UNLOCK 

當我做這最後一步，我有一個問題，因爲我的默認登錄配置了Windows身份驗證，因此指令：

SQLCMD -S .\ 

沒有工作，只是添加sa用戶不使用密碼：

SQLCMD -S .\ -Usa 

希望它能幫助。
