The volume Vol_Tier2 (G:) was not optimized because an error was encountered: The operation requested is not supported by the hardware backing the volume. (0x8900002A)
If I format this volume to NTFS everything works fine. Had no such problem in Server 2012 R2.
Guess defrag.exe is not working with new ReFS v3.1
