ReFS volume inaccessible after update from Windows 10 22H2 to Windows 11 23H2

The starting point of this post was an up-to-date Windows 10 22H2 system, with two mirrored Storage Spaces (one NTFS, the other ReFS).   ReFS always was officially supported in this scenario, as th...

    Since opening this thread in December, I'd like to share two "solutions" (workarounds):

    1) As mentioned before, I attached the ReFS 3.4 volume which wouldn't read on Windows 11, to a Windows Server 2022 system, which auto-updated it to ReFS 3.7. Moving the disks back to the Windows 11 system, I can confirm that they now work fine. Storage Spaces on Windows 11 prompted to upgrade the pool, but the data was readable both before and after this upgrade. The ReFS version remained unchanged at 3.7. This solution does not require purchasing new disks, but it does require access to a Windows Server 2022 system.


    2) The other method is to get new disks and copy the data, using an OS version like Windows 10, which can read the ReFS 3.4 volume which became unreadable after the upgrade to Windows 11.

Hey MikeLabatt, 
I am facing the exact same issue. 
Updated to Windows 11 because of the annoying popups. 
Going back to Windows 10 is not a solution. I can´t read the ReFs File system any more. 

Running  ReFSUtil Salvage -QS I: C:\refsutil  get´s no errors as far as a can see. 
Versión de ReFS: 3.4

Using https://www.reclaime.com/ I can see that all the files are there. 

I have 3 x 4TB drives in parity mode. No hardware problem found.
Now I am waiting for a new drive to copy all my data. 
This is not what I was expecting from a "Resilient " File System.

No solution found yet. Let me know if you get some success.
