对 SQL Server 大数据群集 Active Directory 集成进行故障排除

项目
03/22/2023

适用于： SQL Server 2019 (15.x)

本文介绍了如何对在 Active Directory 模式下部署 SQL Server 大数据群集进行故障排除。

重要

Microsoft SQL Server 2019 大数据群集附加产品将停用。对 SQL Server 2019 大数据群集的支持将于 2025 年 2 月 28 日结束。具有软件保障的 SQL Server 2019 的所有现有用户都将在平台上获得完全支持，在此之前，该软件将继续通过 SQL Server 累积更新进行维护。有关详细信息，请参阅公告博客文章和 Microsoft SQL Server 平台上的大数据选项。

症状

你已开始使用 Active Directory 模式部署 SQL Server 大数据群集。部署停滞不前。

以下示例展示了 bash shell 中的部署结果。

检查当前已部署的 Pod。

kubectl get pods -n mssql-cluster

以下列表仅显示已部署且包含在控制器内的 Pod。没有创建任何计算、数据或存储池 Pod。

检查日志

若要确定部署退出而没有创建计算、数据或存储 pod 的原因，请查看以下日志：

检查 controller.log (<folderOfDebugCopyLog>\debuglogs-mssql-cluster-20200219-093941\mssql-cluster\control-<suffix>\controller\controller\<date>\controller.log)。查找以下条目：

WARN | StatefulSet master is not ready with 0 ready pods and 3 unready pods

检查 master-0 provisioner.log (<folderOfDebugCopyLog>\debuglogs-mssql-cluster-20200219-093941\mssql-cluster\master-0\mssql-server\provisioner\provisioner.log)

原因

在上面的示例中，由于域组的范围设置为本地域，因此部署无法为域用户创建登录名。使用全局或通用范围内的组。若要了解 Active Directory 组范围要求，请参阅在 Active Directory 模式下部署 SQL Server 大数据群集。

验证

检查域组 (<domain-group>) 的范围。使用 get-adgroup。

如果 <domain-group> 组范围是本地域 (DomainLocal)，则部署失败。

下面的 PowerShell 脚本检查名为 bdcadmins 和 bdcusers 的两个 Active Directory 组的范围。将名称替换为你的组的名称。

#Administrators and users Active Directory groups
$Cluster_admins_group='bdcadmins'
$Cluster_users_group='bdcusers'

#Performing Active Directory Group Checks...

#Active Directory admin group Check
$ClusterAdminGroupScope_Result = New-Object System.Collections.ArrayList
try {
    $GroupScope = Get-ADgroup -Identity $Cluster_admins_group | Select-Object -ExpandProperty GroupScope
    
    if ($GroupScope -eq 'DomainLocal') {
        [void]$ClusterAdminGroupScope_Result.Add("Misconfiguration - $Cluster_admins_group Group scope is $GroupScope, this scope is not supported, Please change group scope to either Global or Univesal") 
    }
    else {
        [void]$ClusterAdminGroupScope_Result.Add("OK - $Cluster_admins_group Group scope is $GroupScope")
    }
}
catch {
    [void]$ClusterAdminGroupScope_Result.Add("Error - " + $_.exception.message)
}
#Ad users group check
$ClusterUsersGroupScope_Result = New-Object System.Collections.ArrayList
$GroupScope = ''
try {
    $GroupScope = Get-ADgroup -Identity $Cluster_users_group | Select-Object -ExpandProperty GroupScope
    
    if ($GroupScope -eq 'DomainLocal') {
        [void]$ClusterUsersGroupScope_Result.Add("Misconfiguration - $Cluster_users_group Group scope is $GroupScope, this scope is not supported, Please change group scope to either Global or Univesal")
    } 
    else 
    { [void]$ClusterUsersGroupScope_Result.Add("OK - $Cluster_users_group Group scope is $GroupScope") }
}
catch {
    [void]$ClusterUsersGroupScope_Result.Add("Error - " + $_.exception.message)
}

#Display the results
$ClusterUsersGroupScope_Result

解决方法

若要解决此问题，请创建具有通用范围或全局范围的 Active Directory 组，然后重新运行部署。
