I moved from Windows Server 2012 to 2012 R2. I had several drives attached to the server, including some in storage spaces, formatted as ReFS. After the upgrade I'm getting this warning in the event logs. I don't see any way to upgrade
the file system. The only reference I could find was
this post where the user had some corrupt files, but I don't have any corrupt files. I can't imagine that MS would plan to release a new OS every year, but no way to update file systems for each OS.
