1 TopicCRITICAL - Storage Spaces: ReFS mirrored storage space will not free up space, related Defrag issues
This is an issue introed in the build of Windows 10 1903, first reported 8 months before release. I didn't thought this would be included in to Server 2022 LTSC since I have successfully worked on this to be fixed by the storage team in a Windows 10 Dev build. I have a running SR with MS support for over 1 year now so the fix from Insider dev gets at least backported to 2004 and later. They declined to fix it for 1903, 1909 due to end of support policies. Now this also affects an Server LTSC build for the first time it gets even more "spicy". Due a recent change of my Storage Space I had to "evacuate" all data from the Storage Space and found the same behaviour: issue: - deletion of files on the volume does not free up space (only ReFS mirrored volumes on Storage Spaced (not necessarily S2D, S2D was not tested). The space is shown as used on the Windows Explorer - deletion of files on the volume does not free up space on the Storage Pool affected OS: Windows 10 Pro / Enterprise / EDU 1903, 1909, 2004, 20H1, 20H2, 21H1 (beta channel), Windows Server SAC 1903 or later Windows Server LTSC 2022 LTSC (21H2) open SR: 120072921001646 this is not a local issue and can Feedback Hub (Storage Spaces file deletion issue): https://aka.ms/AAbfubr edit: (possibly related Defrag issues with Storage Spaces) https://aka.ms/AAbmte3Solved6.5KViews2likes11Comments
