我有许多数据库需要将其日志文件移动到新驱动器。有脚本可以在任何地方执行此操作吗？

您需要更改@DestinationFolder值并调整查询以过滤dbs。
目前，这会将所有用户dbs的日志移动到@DestinationFolder位置。我建议注释掉所有的exec sp_executesql @CMD命令并运行，以验证所需的命令是否正确 ：
USE [master]
GO
CREATE proc [dbo].[MoveLog]
as
--enabling xp_cmdshell will be required to do the file move
exec sp_configure 'xp_cmdshell', 1;
reconfigure;
declare @DBName as varchar(128);
declare @LogicalName as varchar(128);
declare @FileLocation as varchar(128);
declare @FileName as varchar(128);
declare @CMD as nvarchar(256);
declare @SourceFolder as varchar(128);
declare @DestinationFolder as varchar(128);
SET @DestinationFolder = 'E:\MSSQL\LOG'; -- Change this to the correct destination folder
BEGIN TRY
declare Db_cursor Cursor forward_only for
select name
from sys.databases
where owner_sid 0x01;--user dbs only
OPEN Db_cursor;
FETCH NEXT FROM Db_cursor
INTO @DBName;
WHILE @@FETCH_STATUS = 0
BEGIN
set @CMD = 'ALTER DATABASE [' + @DBName + '] SET SINGLE_USER WITH ROLLBACK immediate';
Exec sp_executesql @CMD
RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT ;
set @CMD = 'ALTER DATABASE [' + @DBName + '] SET OFFLINE ';
Exec sp_executesql @CMD
RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;
SELECT @LogicalName =name, @FileLocation=physical_name, @FileName = reverse(left(reverse(physical_name), charindex('\', reverse(physical_name)) -1))
FROM sys.master_files
WHERE type_desc = 'LOG' and database_id = DB_ID(@DBName);
--move the log file
set @CMD = 'exec xp_cmdshell N''move "' + @FileLocation + '" "' + @DestinationFolder + '\' + @FileName + '"''';
Exec sp_executesql @CMD
RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;
SET @SourceFolder = REPLACE(@FileLocation,@Filename,'');
/* Update the system catalog */
set @CMD = 'ALTER DATABASE [' + @DBName + '] MODIFY FILE ( NAME = [' + @LogicalName + '], FILENAME = ''' + @DestinationFolder + '\' + @FileName + ''')';
Exec sp_executesql @CMD
RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;
set @CMD = 'ALTER DATABASE [' + @DBName + '] SET MULTI_USER';
Exec sp_executesql @CMD
RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;
set @CMD = 'ALTER DATABASE [' + @DBName + '] SET ONLINE';
Exec sp_executesql @CMD
RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;
FETCH NEXT FROM Db_cursor
INTO @DBName;
END
CLOSE Db_cursor;
DEALLOCATE Db_cursor;
--GO
END TRY
BEGIN CATCH
IF (SELECT CURSOR_STATUS('global','Db_cursor')) >=0
BEGIN
DEALLOCATE Db_cursor;
RAISERROR ('Db_cursor Deallocated in catch',0,1) WITH NOWAIT;
END
SELECT ERROR_LINE(),ERROR_MESSAGE();
END CATCH
exec sp_configure 'xp_cmdshell', 0;
reconfigure;

我知道这是一篇非常古老的帖子。但我认为在这里发布此解决方案比在新帖子中发布更好。
我需要上面的解决方案，但由于减少了停机时间（以上脚本只抓取一个文件），因此同时更改了更多ROWS和LOG文件。如果Destinationlocation与SourceLocation相同，我添加了测试代码，不要使用数据库Ofline。您可以为ROWS和LOG文件定义不同的目标/分区。
我错过的一步是处理文件ACL。在某些情况下，需要一个超过默认的ACL，特别是对于服务或实例帐户。我添加了这一步。使用位于@copyaclScriptLocation的简单Powershell脚本处理ACL设置 剧本来自Jeffrey Snover

.SYNOPSIS
Copy the ACL from one file to other files
.DESCRIPTION
Takes a file and copies its ACL to one or more other files.
.PARAMETER FromPath
Path of the File to get the ACL from.
.PARAMETER Destination
Path to one or more files to copy the ACL to.
.PARAMETER Passthru
Returns an object representing the security descriptor. By default, this cmdlet does not generate any output.
.INPUTS
You can Pipeline any object with a Property named "PSPath", "FullName" or "Destination".
.EXAMPLE
PS> Copy-Acl Referencefile.txt (dir c:\temp\*xml)
.EXAMPLE
PS> dir c:\files *.xml -recurse | Copy-Acl ReferenceFile.txt

评论：
/ *获取复制原始ACL的数据库位置* /
我知道XP_REGREAD Part不是一个很好的解决方案，而且使用Powershell做得更好，但我不知道比获取dataroot目录更好的方法。
此代码段用于SQL实例，可以轻松更改为默认路径
