Windows 10: Re-claim Free Space in Storage Spaces Volume

I have a Win10 machine with 1x 500GB SSD (boot drive) and 3x 3TB HDD. I have storage spaces set up for the HDDs and have noticed that any deleted data in the volume does not change "usage" according to storage spaces. Now it says my volume is full despite having only ~5TB on it. I have linked screenshots of my output where relevant.

• Storage Space Config
• Current Storage Space Status
• Current Drive Status
• Weird allocations per WizTree (this is a couple days old so the #s may not match up exactly with the rest)

How do I get my free space back?


Here is what I tried already after a lot of searching and nothing has worked:

• Optimize Volume via the GUI (0% trimmed; 99% efficiency) - No Changes
• Optimize-Volume Slab Consolidation
• Optimize-Volume Defrag
  • ERROR - Volume Full (I deleted 40GB worth of data and still got a "volume full" error)
  • I tried this defrag manually before the drive was "full" and it ran the defrag but I didnt get any space back
• Chkdsk
• Empty Recycle bin, restart, etc.

Is there anything I can do short of deleting the volume and starting over?

Can I prevent in the future? Because if this is just the nature of Storage Spaces they won't work for me.

Any way to downgrade ver. of MS Storage spaces volume w/o data loss?


1. Install Windows 1607 & 1709 dual boot system
2. Connect two free disks
3. Boot into 1607
4. Create storage pool, assign two free disks, create two-way mirror volume
5. Copy data to new volume
6. Reboot into 1709
7. Upgrade your Storage Space pool to gain new features as MS suggests
8. Reboot into 1607
9. Your Storage Space configuration looks now as in the picture, volume is inaccessible
10. Notice that doing step 7 was not the smartest idea, data are now accessible only from Windows 1709.

Question: Is it possible to simply revert Storage Spaces metadata back to version 1607? Answer: No. It is necessary to backup data, destroy upgraded pool, create new pool & mirror in Windows 1607, and restore data.

Is it so hard to understand what necros asks for?

 

Storage Space

Surface Pro 3 storage space is low. Storage settings say that Apps and Games is using 17.5 GB but when I add up the space from the list of apps it is only 5.7 GB. What is taking up up the other ~12 GB and how do I free up space?

 

How to restore a volume accidentally deleted from Storage Spaces

Need urgent help here:

1. I have a Mass Storage Space created in Windows 10 and it includs 3 disks

2. In Disk Manager, I accidentally deleted the volume on the storage space

3. The files are all there intact on the three disk as in the Storage Space management page the disks are all showing as being at capacity (see attached screen shot below)

4. In disk manager, the D drive previously associated with the Storage Space is now showing as unallocated

Question: Is it possible to restore the volume on the storage space? If I create a volume on the D drive without formatting it, would that allow me to access all the files still in the Storage Space?

Thanks!
