I've been trying to figure this out now for sometime, but haven't found an answer.
I have a Server 2016 VM running on HyperV Server 2016.
It has a file storage VHDX formatted as NTFS that is sitting on a mirrored storage spaces virtual disk running ReFS.
Will the files on the VHDX have the benefits of the file integrity streams or would I need to do REFS on both the storage spaces and the VHDX?
