Windows 10: Random 100% usage on Storage spaces volumes freezes system.

I have Windows 10 pro, and I have a windows Storage Pool of 65.4 TB, and four 16 TB volumes with parity. Randomly, a volume will peg at 100% utilization. I see no disk activity out of the ordinary in task manager, yet the performance tab shows the volumes pegged for usage. This will cause the system to slow radically, and stop functioning after a short amount of time.I have used a number of tips I have found online to try to fix this, including disabling indexing, superfetch, changed MSISupported to '0' for all storahci.sys drivers. Updated all drivers... I have seven hard drives, each at 7200

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?

 

Random 100% disk usage spike causing frozen system

ok, there's nothing wrong with my disk.

But I was playing a pc game on this, and laptop froze twice while the disk usage shot to 100%
with no read or write occurring.

Once it finishes whatever it's doing, I can resume using my computer.

What the hell is this bug no one has been able to figure out?

Windows 10 freezes, Disk usage 100 - Microsoft Community
This is the same thing I'm talking about, but it looks like some cockroach that can't be killed.

my system driver is iastorA.sys, but the generic ahci.sys driver affects many computers as well.
Both drivers cause Error 129

stupid win10 bug.
