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.

MicrosoftAgreed. Note however that refs v1 does not get auto updated to v3
That only happens on the v3.x versions ie 3.1>3.4->3.7
Hence why 'stuck' with older refs v1 volumes in some cases
ANother option is to to boot the 'Recovery OS' or boot from an Install iso /usb and select reapir. That will be a base OS version (without patches) and can access the data on refsv1 and copy it off.
Reminder - all this hassle only affects drives that are removable or have charactereistics of removable (like on vmware).
With the exception of Mikes original issue which is a weird and unexplained one.

Thanks for clarification Stephen!
One question aside if a customer uses WinPE or WinRE from Win10/2016/2019/2022 is this one able to read ReFS natively, I am aware it is not for Storage Spaces.
Some still use Windows Backup to backup files this be restored? TY.
