与其他任何功能一样， Windows 10 功能升级^{(Feature Upgrade)}也有自己的一系列问题，而且似乎 2004 版在 Storage 方面存在很多问题^{(issues around Storage)}。限制Windows 10升级的问题之一与Parity Storage Spaces相关。Windows 10 电脑收到一条错误消息：

This PC can’t be upgraded to Windows 10. Your PC isn’t supported on this version of Windows. No Action is needed. Windows Update will offer this version of Windows 10 automatically once the issue has been resolved.

虽然这听起来像是一般错误，但其中一个原因是因为更新到Windows 10版本 2004 和Windows Server版本 2004 后^{(Windows Server)}奇偶校验存储空间^{(Parity Storage Spaces)}的问题。

错误原因

如果您的Windows 10 PC 使用Parity Storage Spaces，则在更新到Windows 10 2004（包括服务器版本）后，存储使用矿石访问可能会出现问题。使用某些配置时，它将在磁盘管理器中显示^{(Disk Manager)}Parity Storage Spaces   RAW  。但是，简单存储空间^{(Simple Storage Spaces)}和镜像存储空间^{(Mirror Storage spaces)}不受此问题的影响。

Parity Storage Spaces 非常适合视频等大文件，并且与其他文件相比；他们不需要双倍的驱动器。虽然性能很慢，但它们非常适合媒体文件。

也就是说，微软^(Microsoft)已经详细说明了一个解决方案，其中包含一组关于你现在应该做什么的警告。虽然Windows Update不允许您升级，但如果您已强制升级，则会出现以下两个警告：

• 恢复到以前版本的Windows并不能解决受影响设备上的此问题。
• 不要在受此问题影响的任何设备上运行chkdsk 命令。

解决方法是应用这些步骤并等待完全缓解或更新以解决此问题。如果您尝试使用任何存储工具，都会导致文件损坏，尤其是当卷 在 磁盘管理器中显示为^{(Disk Manager.)}RAW时。^(RAW)

解决奇偶校验存储空间^{(Parity Storage Spaces)}可访问性的解决方法

Use WIN + X打开电源^(Power)菜单，然后选择PowerShell（管理员）。^{(PowerShell (admin).)}在PowerShell窗口中，键入并执行以下命令 -

Get-VirtualDisk | ? ResiliencySettingName -eq Parity | Get-Disk | Set-Disk -IsReadOnly $true

此命令会将您的存储空间^(Spaces)设置为只读。它将确保数据可访问且不会丢失。但是，您将无法给他们写信。

最大的缺点之一是，如果您的卷被视为RAW ，则应该是可读的；不起作用。这只意味着解决方法不是完全证明，如果你还没有升级，请不要仅仅因为你可以强制升级Windows 。

注意^(NOTE)：Microsoft 已针对用户在将Windows 10升级到下一个版本后可能面临的奇偶校验存储空间问题发布了 Windows 疑难解答。^{(Windows Troubleshooters for Parity Storage Spaces)}

This PC can't be upgraded to Windows 10 due to Parity Storage Spaces

A Windows 10 Feature Upgrade has, like any other, has their own set of issues, and seems like version 2004 has a lot of issues around Storage. One of the issues which have been restricting Windows 10 to upgrade is related to Parity Storage Spaces. Windows 10 PCs receive an error saying—

This PC can’t be upgraded to Windows 10. Your PC isn’t supported on this version of Windows. No Action is needed. Windows Update will offer this version of Windows 10 automatically once the issue has been resolved.

While that sounds like a general error, one of the reasons is because of the issue with Parity Storage Spaces after updating to Windows 10, version 2004, and Windows Server, version 2004.

Cause of the error

If your Windows 10 PC is using Parity Storage Spaces, the storage might have issues using ore accessing after updating to Windows 10 2004, including server version. It will display the Parity Storage Spaces  RAW in Disk Manager when using some configurations. However, Simple Storage Spaces and Mirror Storage spaces are not affected by this issue.

Parity Storage Spaces are excellent for large files such as videos and compared to others; they do not require double the drives. While the performance is slow, but they work out great for media files.

This PC can’t be upgraded to Windows 10 – Parity Storage Spaces

That said, Microsoft has detailed a solution with a set of warnings on what you should now be doing. While Windows Update will not allow you to upgrade, if you have forced upgrade, then here are two warnings:

• Reverting to previous versions of Windows does not resolve this issue on affected devices.
• Do not run the chkdsk command on any device affected by this issue.

The workaround is to apply the steps and wait for full mitigation or update to address this issue. If you attempt any of the storage tools, it will result in damaging the fils, especially if the volume shows as RAW in Disk Manager.

Workaround to resolve Parity Storage Spaces accessibility

Use WIN + X to open the Power menu, and select PowerShell (admin). In the PowerShell window, type and execute the following command-

Get-VirtualDisk | ? ResiliencySettingName -eq Parity | Get-Disk | Set-Disk -IsReadOnly $true

This command will set your Storage Spaces into read-only. It will make sure the data is accessible and not lost. However, you will not be able to write to them.

One of the biggest drawbacks is that if your volume is seen as RAW should be readable; it will not work.  It only means the workaround is not full proof, and if you haven’t upgraded, kindly do not force upgrade Windows just because you can.

NOTE: Microsoft has released the Windows Troubleshooters for Parity Storage Spaces issues which users may face after upgrading Windows 10 to the next version.
