Question Win10 Storage Spaces - Mirrored Pool Doesn't Release Space

[NeverSummerTP]

Using Storage Spaces for a simple Mirrored Pool with (2) 4TB HDD's for a backup drive.

Setup was simple and easy with Storage Spaces reporting a formatted 3.75TB Mirrored Volume.

After test writing some system images and doing some disk speeds tests, Storage Spaces says drives are over 80% full with a warning, but there isn't any kept data on there.

Under Computer Management, the Volume says only 15% used.

So it's like deleted files (also deleted from recycle bin) don't get reported as free space back to the Storage Space Console.

I have also created a SIMPLE storage space with (2) SSD's, but deleted files and space seems to be reclaimed there.

I have enabled Disk Optimizer to run once a week but it doesn't help to reclaim the space on the MIRRORED volume of HDD's.

Dumb question. Did you do a restart after deleting the files as tho they are removed from the file system the memory of their existence remains until a restart.
