Moving System Files

Having built one database server in my new environment, the second one is an awful lot easier.

The following six lines of code saved me a ton of time this morning.

ALTER DATABASE [tempdb] MODIFY FILE (name = tempdev, FILENAME = ‘D:\TempDB\tempdb.mdf’)
ALTER DATABASE [tempdb] MODIFY FILE (name = templog, FILENAME = ‘D:\TempDB\templog.ldf’)
ALTER DATABASE [msdb] MODIFY FILE ( NAME = msdbdata , FILENAME = ‘G:\system\MSDBData.mdf’ )
ALTER DATABASE [msdb] MODIFY FILE ( NAME = msdblog , FILENAME = ‘e:\system\MSDBLog.ldf’ )
ALTER DATABASE [model] MODIFY FILE ( NAME = modeldev , FILENAME = ‘G:\system\model.mdf’ )
ALTER DATABASE [model] MODIFY FILE ( NAME = modellog , FILENAME = ‘e:\system\modellog.ldf’ )

I just can’t explain how big of a deal this is to me. In my current envrionment, every server was set up with a single C: drive. Some of these file systems are over a terabyte. Now we’re breaking things up, and I can only imagine the performance boost we’re going to see.
