Windows Storage Space shows a lot less room on my space than I am using!

I had a 8 drive pool (Z Drive), each drive was 6 TB. I have two 6 drive enclosures and since I cannot change the cluster size I could not expand my storage space to 12 drives. So I added four 4TB drives to the second enclosure and moved data (deleted 1.7 TB and moved around 8ish TB to the new pool) and now I have two 6 drive pools each with their own storage space (goal is that if an enclosure fails I can just switch my most important 6 drive pool to my other enclosure - maybe I should have created a second storage space within the same pool and moved the files to that - but I created two pools instead). The second pool and volume (X Drive) is all fine, but the original pool and it's volume (Z drive) shows almost full and it shouldn't be, as follows ...

Reading from the top down in Manage Storage Spaces ...

Storage Pool----------------

Using 30.2 TB of 32.7 TB pool capacity ... on the right side : Low capacity; add drives

Storage Spaces -------------

Z New (Z:)
Two-way mirror
15.9 TB
Using 30.2 TB pool capacity

Physical Drives------------------

The following repeats 6 times for the six identical drives ...
Drive ID
Serial Number
Attached via SATA
92.4% used
Providing 5.45 TB pool capacity

In File Explorer, drive properties my Z drive shows ...

Used space 5.83 TB (I even checked properties for each folder and it adds up)
Free Space 10.1 TB
Total Capacity 15.9 TB

Things I have done ...
Optimize Drive Usage
Rebooted computer
Emptied the Trash

I am nervous that this inconsistency reflects a problem and appreciate any help! Thanks!

No, I am afraid I didn't find anything that addressed my issues in the guide you linked to. No specifications for space locked after deleting volumes or removing drives from the pool causing incorrect reporting of space available. I wiped the pool, recreated and moved my data back, so this issue is temporarily fixed. But I have another pool where I have changed drives/space after creating the pool (numbers seem to be off some) and if I change anything in the future I can certainly run into this again - so I would really like to understand what is going on.

Thanks.

Hi Roger,
Since log analysis is actually not within the forum scope, I would suggest that you raise a MS support ticket as this issue might need deeper investigation. In addition, if the issue has been proved as system flaw, the consulting fee would be refund. You may find phone number for your region accordingly from the link below.

Thanks for your understanding.
Best regards,
