Microsoft confirms Storage Spaces issue in Windows 10 v2004

by ·

Earlier we mentioned that Windows 10 Version 2004 may destroy the storage pool and storage space functions, resulting in the inability to create new storage spaces.

In fact, Microsoft has not publicly acknowledged this problem until now, although the inability to create new storage space is an obvious and easily discovered problem.

Microsoft has confirmed this issue and released supporting documentation to explain it. Now users will be prevented from upgrading the new version if Parity Storage Spaces is enabled. Microsoft explains:

If you have already updated to Windows 10, version 2004 and are affected by this issue:

  • We recommend you check that the troubleshooter has run or apply the steps below and wait for a full mitigation or an update to address this issue. Attempts to mitigate the issue using methods not mentioned in this article might result in damaging of files, especially if the volume shows as RAW in Disk Manager.
  • Reverting to previous versions of Windows does not resolve this issue on affected devices.
  • We do not recommend running the chkdsk command on any device affected by this issue.

If you are using Windows Server, version 2004 or the troubleshooter has not yet run, you can use the following instructions to mark them as read only:

  1. Select Start and type: powershell
  2. Right click or long press on Windows PowerShell and select Run as administrator.
  3. If prompted by a User Access Control dialog for Windows Powershell, select yes.
  4. Within the PowerShell dialog, type the following command and press enter: Get-VirtualDisk | ? ResiliencySettingName -eq Parity | Get-Disk | Set-Disk -IsReadOnly $true
  5. Your Storage Spaces should now be set to read only, meaning you will not be able to write to them.  Your device will still be usable, and any volume not seen as RAW should be readable.

Note The above steps are the equivalent to the troubleshooter above titled Hardware and devices troubleshooter.  There is currently no manual equivalent to the troubleshooter titled Storage space troubleshooter.
