DSC配置故障排除

我正在寻找有关如何解决DSC配置问题的建议。我正在使用Azure DSC Extension,日志是:

VERBOSE: [2017-09-08 02:56:48Z] [VERBOSE] [sql-sql-0]:                         
   [[xSqlServer]ConfigureSqlServerWithAlwaysOn] The file "MSDBLog" has been 
modified in the system catalog. The new path will be used the next time the 
database is started.
VERBOSE: [2017-09-08 02:56:50Z] [ERROR] Exception setting "StartupParameters": 
"STARTUPPARAMETERS: unknown property."
VERBOSE: [2017-09-08 02:56:50Z] [VERBOSE] [sql-sql-0]:                         
   [[xSqlServer]ConfigureSqlServerWithAlwaysOn] Stopping SQL server instance 
'MSSQLSERVER' ...
VERBOSE: [2017-09-08 02:57:07Z] [VERBOSE] [sql-sql-0]:                         
   [[xSqlServer]ConfigureSqlServerWithAlwaysOn] Starting SQL server instance 
'MSSQLSERVER' ...

从那里它冻结然后超时。 这是我的DSC配置中唯一使用xSQLServer的部分:

xSqlServer ConfigureSqlServerWithAlwaysOn
{
    InstanceName = $env:COMPUTERNAME
    SqlAdministratorCredential = $Admincreds
    ServiceCredential = $SQLCreds
    MaxDegreeOfParallelism = 1
    FilePath = "F:\DATA"
    LogPath = "G:\LOG"
    DomainAdministratorCredential = $DomainFQDNCreds
    DependsOn = "[xSqlLogin]AddSqlServerServiceAccountToSysadminServerRole"
}

这是MicrosoftAzure_xSqlServer.psm1的一部分,其中包含“启动”的提及:

function Alter-SystemDatabaseLocation([string]$FilePath, [string]$LogPath,[PSCredential]$ServiceCredential )
{
    $permissionString = $ServiceCredential.UserName+":(OI)(CI)(F)"
    icacls $FilePath /grant $permissionString
    icacls $LogPath /grant $permissionString

    Invoke-Sqlcmd "Use master"
    Invoke-sqlCmd "ALTER DATABASE tempdb MODIFY FILE (NAME = tempdev, FILENAME = '$FilePath\tempdb.mdf');"
    Invoke-sqlCmd "ALTER DATABASE tempdb MODIFY FILE (NAME = templog, FILENAME = '$LogPath\templog.ldf');"

    Invoke-sqlCmd "ALTER DATABASE model MODIFY FILE (NAME = modeldev, FILENAME = '$FilePath\model.mdf');"
    Invoke-sqlCmd "ALTER DATABASE model MODIFY FILE (NAME = modellog, FILENAME = '$LogPath\modellog.ldf');"

    Invoke-sqlCmd "ALTER DATABASE msdb MODIFY FILE (NAME = MSDBData, FILENAME = '$FilePath\msdbdata.mdf');"
    Invoke-sqlCmd "ALTER DATABASE msdb MODIFY FILE (NAME = MSDBLog, FILENAME = '$LogPath\msdblog.ldf');"

    [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SqlWmiManagement')| Out-Null
    $smowmi = New-Object Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer 
    $sqlsvc = $smowmi.Services | Where-Object {$_.Name -like 'MSSQL*'} 
    $OldStartupParameters = $sqlsvc.StartupParameters
    $params = '-d'+$FilePath+'\master.mdf;-e'+$LogPath+'\ERRORLOG;-l'+$LogPath+'\mastlog.ldf'
    $sqlsvc[1].StartupParameters = $params
    $sqlsvc[1].Alter()
}

理解问题的下一步应该是什么? 如果它有所不同,我正在尝试使用适用于Windows Server 2012 R2和SQL Server 2014的模板和DSC代码在Windows Server 2016和SQL Server 2016 SP1上创建SQL Server Always On Availability组。

我的建议是使用现有的工作代码;)我认为复制粘贴blog post并不合理。但是我会在这里留下相关文件的链接。

链接:
1. DSC modules
2. ARM Template。注意:部署sql的Arm模板需要已经有vnet和域。此外,您将很难尝试在该框架之外部署此模板,因此可能只需复制dsc extension \ dsc脚本并在部署中使用。
3. Parameters file example

xSqlServer(新的)无法将sql移动到另一个磁盘,因此您无法使用自定义脚本或此旧版xSql模块。此外,请注意,包内的DSC模块已被修改。 这些DSC配置不适用于未修改的模块版本function clickAny(button){ button.click() } xSqlCreateVirtualDataDiskxDatabase可能还有其他一些模块,我不记得了点)。

PS。使用该配置并修补相关部件并不是一个愉快的旅程...... PPS。该repo还包含ADDS的dsc配置,也可以并行运行(与官方示例相比)。

试试这个。

$sqlsvc = $smowmi.Services | Where-Object {$_.Name -eq 'MSSQLSERVER'}  
$OldStartupParameters = $sqlsvc.StartupParameters
$params = '-d'+$FilePath+'\master.mdf;-e'+$LogPath+'\ERRORLOG;-l'+$LogPath+'\mastlog.ldf'
$sqlsvc[0].StartupParameters = $params
$sqlsvc[0].Alter()
