管理容量Manage capacity

内存Memory

若要增加 Azure Stack Hub 的总可用内存容量，可以添加更多内存。To increase the total available memory capacity for Azure Stack Hub, you can add additional memory. 在 Azure Stack Hub 中，物理服务器也称为“缩放单元节点”。In Azure Stack Hub, your physical server is also referred to as a scale unit node. 属于单个缩放单元的所有缩放单元节点必须具有相同的内存量。All scale unit nodes that are members of a single scale unit must have the same amount of memory.

保留期Retention period

云操作员可以使用保留期设置来指定时间间隔天数（0 到 9999 天），在此期间，任何已删除的帐户都有可能能够恢复。The retention period setting lets a cloud operator to specify a time period in days (between 0 and 9999 days) during which any deleted account can potentially be recovered. 默认保留期设置为 0 天。The default retention period is set to 0 days. 将值设置为 0 表示任何已删除的帐户会立即超出保留期，并标记为定期进行垃圾回收。Setting the value to 0 means that any deleted account is immediately out of retention and marked for periodic garbage collection.

获取缩放单元指标Get scale unit metrics

可以使用 PowerShell 获取戳记使用情况信息，不需 Azure 支持提供帮助。You can use PowerShell to get stamp utilization information without help from Azure Support. 若要获取戳记使用率，请执行以下操作：To obtain stamp utilization:

1. 创建 PEP 会话。Create a PEP session.
2. 运行 test-azurestack。Run test-azurestack.
3. 退出 PEP 会话。Exit PEP session.
4. 使用 invoke-command 调用运行 get-azurestacklog -filterbyrole seedring。Run get-azurestacklog -filterbyrole seedring using an invoke-command call.
5. 提取 seedring .zip。Extract the seedring .zip. 可以从运行 test-azurestack 的 ERCS 文件夹获取验证报告。You can obtain the validation report from the ERCS folder where you ran test-azurestack.

有关详细信息，请参阅 Azure Stack Hub 诊断。For more information, see Azure Stack Hub Diagnostics.

排查虚拟机 (VM) 的问题Troubleshoot virtual machines (VMs)

重置 Linux VM 密码Reset Linux VM password

如果你忘记了 Linux VM 的密码，并且因为 VMAccess 扩展出现问题，“重置密码”选项不起作用，你可执行以下步骤进行重置：If you forget the password for a Linux VM and the Reset password option is not working due to issues with the VMAccess extension, you can perform a reset following these steps:

1. 选择要用作恢复 VM 的 Linux VM。Choose a Linux VM to use as a recovery VM.

2. 登录到用户门户：Sign in to the User portal:

   1. 记下 VM 大小、NIC、公共 IP、NSG 和数据磁盘。Make a note of the VM size, NIC, Public IP, NSG and data disks.
   2. 停止受影响的 VM。Stop the impacted VM.
   3. 删除受影响的 VM。Remove the impacted VM.
   4. 将受影响的 VM 中的磁盘作为数据磁盘附加到恢复 VM 上（可能需要花费几分钟时间才能使用该磁盘）。Attach the disk from the impacted VM as a data disk on the recovery VM (it may take a couple of minutes for the disk to be available).

3. 登录到恢复 VM，并运行以下命令：Sign in to the recovery VM and run the following command:

   sudo su -
   mkdir /tempmount
   fdisk -l
   mount /dev/sdc2 /tempmount /*adjust /dev/sdc2 as necessary*/
   chroot /tempmount/
   passwd root /*substitute root with the user whose password you want to reset*/
   rm -f /.autorelabel /*Remove the .autorelabel file to prevent a time consuming SELinux relabel of the disk*/
   exit /*to exit the chroot environment*/
   umount /tempmount
   

4. 登录到用户门户：Sign in to the User portal:

   1. 从恢复 VM 拆离该磁盘。Detach the disk from the Recovery VM.
   2. 从磁盘重新创建 VM。Recreate the VM from the disk.
   3. 请务必从前一个 VM 传输公共 IP、附加数据磁盘等。Be sure to transfer the Public IP from the previous VM, attach the data disks, etc.

还可以拍摄原始磁盘的快照并从中创建新磁盘，而不是直接在原始磁盘上执行更改。You may also take a snapshot of the original disk and create a new disk from it rather than perform the changes directly on the original disk. 有关详细信息，请参阅以下主题：For more information, see these topics:

• 重置密码Reset password
• 从快照创建磁盘Create a disk from a snapshot
• 更改和重置根密码Changing and resetting the Root password

预配期间，Windows Server 2012 R2 的许可证激活失败License activation fails for Windows Server 2012 R2 during provisioning

在这种情况下，Windows 将无法激活，此时屏幕右下角将显示一个水印。In this case, Windows will fail to activate and you will see a watermark on the bottom-right corner of the screen. 位于 C:\Windows\Panther 下的 WaSetup.xml 日志包含以下事件：The WaSetup.xml logs located under C:\Windows\Panther contains the following event:

<Event time="2019-05-16T21:32:58.660Z" category="ERROR" source="Unattend">
    <UnhandledError>
        <Message>InstrumentProcedure: Failed to execute 'Call ConfigureLicensing()'. Will raise error to caller</Message>
        <Number>-2147221500</Number>
        <Description>Could not find the VOLUME_KMSCLIENT product</Description>
        <Source>Licensing.wsf</Source>
    </UnhandledError>
</Event>

若要激活许可证，请复制要激活的 SKU 的自动虚拟机激活 (AVMA) 密钥。To activate the license, copy the Automatic Virtual Machine Activation (AVMA) key for the SKU you want to activate.

在 VM 上运行以下命令：On the VM, run the following command:

slmgr /ipk <AVMA_key>

若要获取完整的详细信息，请参阅 VM 激活。For complete details, see VM Activation.

默认映像和库项Default image and gallery item

在 Azure Stack Hub 中部署 VM 之前，必须先添加 Windows Server 映像和库项。A Windows Server image and gallery item must be added before deploying VMs in Azure Stack Hub.

我已删除某些 VM，但仍在磁盘上看到 VHD 文件I've deleted some VMs, but still see the VHD files on disk

此行为是设计使然：This behavior is by design:

• 删除 VM 时，不会删除 VHD。When you delete a VM, VHDs aren't deleted. 磁盘是资源组中的独立资源。Disks are separate resources in the resource group.
• 删除某个存储帐户后，Azure 资源管理器会立即反映删除结果。When a storage account gets deleted, the deletion is visible immediately through Azure Resource Manager. 但是，该存储帐户包含的磁盘仍保留在存储中，直到运行垃圾收集为止。But the disks it may contain are still kept in storage until garbage collection runs.

如果看到“孤立的”VHD，必须知道它们是否包含在已删除的存储帐户的文件夹中。If you see "orphan" VHDs, it's important to know if they're part of the folder for a storage account that was deleted. 如果未删除存储帐户，则正常情况下会保留这些 VHD。If the storage account wasn't deleted, it's normal that they're still there.

可以在管理存储帐户中详细了解如何配置保留阈值和按需回收。You can read more about configuring the retention threshold and on-demand reclamation in manage storage accounts.

排查存储问题Troubleshoot storage

存储回收Storage reclamation

回收的容量最长可能需要在 14 小时后才显示在门户中。It may take up to 14 hours for reclaimed capacity to show up in the portal. 空间回收取决于不同的因素，包括块 Blob 存储中内部容器文件的用量百分比。Space reclamation depends on different factors including usage percentage of internal container files in block blob store. 因此，我们无法保证运行垃圾回收器时可回收的空间量，这取决于删除的数据量。Therefore, depending on how much data is deleted, there's no guarantee on the amount of space that could be reclaimed when garbage collector runs.

Azure 存储资源管理器不兼容 Azure Stack HubAzure Storage Explorer not working with Azure Stack Hub

如果在离线场景中使用集成系统，建议使用企业证书颁发机构 (CA)。If you're using an integrated system in a disconnected scenario, it's recommended to use an Enterprise Certificate Authority (CA). 以 Base-64 格式导出根证书，然后将其导入 Azure 存储资源管理器。Export the root certificate in a Base-64 format and then import it in Azure Storage Explorer. 确保从资源管理器终结点中删除尾部斜杠 (/)。Make sure that you remove the trailing slash (/) from the Resource Manager endpoint. 有关详细信息，请参阅准备连接到 Azure Stack Hub。For more information, see Prepare for connecting to Azure Stack Hub.

对应用服务进行故障排除Troubleshoot App Service

Create-AADIdentityApp.ps1 脚本失败Create-AADIdentityApp.ps1 script fails

如果应用服务所需的 Create-AADIdentityApp.ps1 脚本失败，请确保在运行该脚本时包含必需的 -AzureStackAdminCredential 参数。If the Create-AADIdentityApp.ps1 script that's required for App Service fails, be sure to include the required -AzureStackAdminCredential parameter when running the script. 有关详细信息，请参阅在 Azure Stack Hub 上部署应用服务的先决条件。For more information, see Prerequisites for deploying App Service on Azure Stack Hub.

对 Azure Stack Hub 更新进行故障排除Troubleshoot Azure Stack Hub updates

Azure Stack Hub 修补程序和更新过程旨在让操作员以一致且简单的方式应用更新包。The Azure Stack Hub patch and update process is designed to allow operators to apply update packages in a consistent, streamlined way. 虽然不常见，但在修补和更新过程中可能会出现问题。While uncommon, issues can occur during patch and update process. 如果在修补和更新过程中遇到问题，建议执行以下步骤：The following steps are recommended should you encounter an issue during the patch and update process:

0. 先决条件 ：请确保已遵循 更新活动清单，并 启用主动日志收集。Prerequisites : Be sure that you have followed the Update Activity Checklist and enable proactive log collection.

1. 按照在更新失败时创建的失败警报中的补救步骤进行操作。Follow the remediation steps in the failure alert created when your update failed.

2. 如果无法解决问题，请创建 Azure Stack Hub 支持票证。If you have been unable to resolve your issue, create an Azure Stack Hub support ticket. 请确保已针对发生问题的时间跨度收集日志。Be sure you have logs collected for the time span when the issue occurred.
