Windows 10: Just upgraded to Windows 11 and Storage Spaces is broken

We have an HP Z4 G4 Tower Workstation we purchased in 2018 that we just upgraded to Windows 11. We have a Thunderbolt card in it from HP and 2 OWC Thunderbay 6 Drive Enclosures plugged into it. The OWC Drive enclosures are set up as Storage Spaces and worked great with Windows 10. On upgrade to Windows 11 nothing. I open Storage Spaces and the storage space shows. It stated I needed to update the storage space which I did. The Drive now shows in File Explorer but has nothing where it would normally indicate size and room available.The drives in the Thunderbay are formatted Refs. I found with

Storage Space and Space Pooling in x32Win10ProV20H2

Storage Spaces seems not much used, and some of those who have used it have had some bad experiences.

As your experience suggests, maintaining the integrity of your disks- continuous monitoring for degradation- is vital.

MS has broken Storage Spaces from time to time, in particular when upgrading:

A couple of users have found moving a storage space from one PC to another didn't work.

Storage Spaces Disappears After Replacing Boot Drive

Did you check Windows View update history list to see if KB4568831 has already been installed? I would think it has and that is why you got the message you did.

If you have not run the Storage Spaces troubleshooter there are instructions in the other link on do it manually. What is accomplished in either case is that your storage spaces will be set to read only which will allow you to have access to the data on your storage space drive.

The latter manual steps return the Storage Spaces drive to read/write and run optimization, defrag, and integrity routines. If your install is up to date then you should find the cumulative update KB4568831 installed in history. If you have upgraded to 20H2 then the patch discussed elsewhere to address the issue with Storage Spaces showing as RAW is rolled into the upgrade. In either case the manual optimization, defrag, and integrity routines can be run.
