Unable to start SQL Server Instance 2008 R2 - DB file corrupt
- by Velu
I was not able to start the SQL Server 2008 R2 production DB instance. After reading the log file error message is
" The log scan number passed to log scan in database ‘master’ is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication."
After reading several post i realize that my MASTER DB file is corrupted. I have followed the below setup
Copy the Master.mdf and Masterlog.ldf file from Template location to My Database Data folder.
C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn\Templates to D:\MSSQL\MSSQL10_50.MSSQLSERVER\MSSQL\DATA
Note: Same error occur when i copy the all DB file like Master, MasterLog, MSDBData, MSDBlog, Model and ModelLog
When i run my MSSQLSEVER instance different problem occur.
In My server i had only C, D- Drive i dont have the E drive. How can i override these below error path.
