由於無法訪問文件或內存不足或磁盤空間不足，無法打開數據庫'msdb'

Question

我在我的一個客戶端系統中遇到此問題。 當我們通過SSMS連接到SQL Server 2008數據庫引擎，我正在錯誤

Database 'msdb' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. (Microsoft SQL Server, Error: 945)

然後也連接到數據庫。但客戶端數據庫不可見。如果我試圖再次擴展'系統數據庫'或'安全'或'管理'，我收到這個錯誤。

硬盤有80 GB的可用空間，帳戶權限，.mdf和.ldf文件不只讀

在SQL Server配置管理器 - > SQL Server屬性 - >登錄爲 - >選擇「這帳戶「並使用帳戶名稱」admin「及其密碼。

他們能夠通過來自其他PC的應用程序進行數據操作。問題僅限於從SSMS訪問。

在錯誤日誌中，我們可以看到

請給我建議我們如何才能糾正這個

因爲我MSDB文件已損壞，並沒有系統數據庫的備份，我必須重建MSDB數據庫幸運的是，沒有工作或警報等......我試圖從以下鏈接步驟 Rebuild System Databases

在執行計劃只有一個更改是在第6步從重新生成MSDB從instmsdb.sql。 由於發生錯誤，我在命令提示符下停止了SQL Server服務，並從配置管理器啓動。 然後打開SSMS，連接到數據庫引擎（我得到一個錯誤，單擊確定），然後，從 C：\ Program Files \ Microsoft SQL Server \ MSSQL10.MSSQLSERVER \ MSSQL \ Install \ instmsdb打開instmsdb.sql。 sql並執行。
