ReFS volume appears RAW (version doesn't match expected value) after Windows Update
After Windows Update last night, Windows Server 2019 wouldn't mount a storage space volume as ReFS (it appears as RAW). The error in the ReFS event log is "ReFS failed to mount the volume. Version 1....
I solved this by uninstalling KB5009557. The ReFS volume came back working as it should, instead of appearing as RAW.
Update: since even the February 2022 Windows Update bricks ReFS in the same way, and hints from Microsoft are that ReFS 1.x is no longer supported, we copied everything to new disks, upgrading ReFS from 1.2 to 3.4 in the process. Such a (manual) ReFS upgrade should be the solution that everyone needs, allowing to re-enable Windows Update.
Can definitely confirm that Server 2019 Datacenter is still experiencing the ReFS issue after updating, and the only other patch that appears in Updates is KB5010791. It doesn't solve the issue either.
Can't believe it's been this long and there still isn't a fix for this on 2019 when it's obviously an issue (whether MS wants to admit it or not).
The only fix so far for 2019 is to uninstall both KB5010791 and KB5009557. And then not run Windows Updates again until it's finally acknowledged and fixed.

- just installed KB5010791 to fix ReFS issue. Did not solve the problem on Server 2019. Volume still is not available.
Seems like a joke that "The Resilient File System (ReFS) is Microsoft's newest file system, designed to maximize data availability, scale efficiently to large data sets across diverse workloads, and provide data integrity with resiliency to corruption" is getting useless due to an until now unfixed MS Bug.- Possible solution to fix this issue:
I wondered about the fact that only "removable" devices were affected.
So i changed the "devices.hotplug" value in VM config to "false".
This is dissabling the hotplug for the VM.
After starting the server 2019 my ReFS HD was back.
Simple to do and i do not see big side effects.
Hope it helps somebody.After almost attempting a FS repair, I found someone on reddit that mentioned your post. This saved me some headache. I tried to passthru a device and changed this option to TRUE. Changing it to FALSE and it came right back. Thank you.
