Storage spaces, Resize-Partition : Invalid Parameter

Hello,
I am facing a problem when trying to resize a volume under storage spaces.
In powershell I can extend the virtualdisk but afterwards when I try to extend the partition I get the following error
The following screenshot is to demonstrate the issue


Resize-Partition : Invalid Parameter
Activity ID: {5333086d-a957-0003-d208-335357a9d301}
At line:1 char:1
+ Resize-Partition -Size 37.1TB -DriveLetter h
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (StorageWMI:ROOT/Microsoft/.../MSFT_Partition) [Resize-Partition], CimException
+ FullyQualifiedErrorId : StorageWMI 5,Resize-Partition


As a result the virtualdisk can resize with no problems and right now is at 37.2TB, but the volume is still 28.9TB


The storage spaces have more than enough free space and also I have successfully created a 60.4TB volume W: which is empty.
My data is on H: and this is the volume I cannot resize


Note that I have successfully resized the storage space some months ago following the same procedure and my guess is that in the recent updates this ability has been messed up. I have the same issue on two other pcs with storage spaces that cannot be extended.
Windows 10 Pro for workstations v1709 build 16299.248


Has anyone faced the same problem lately? And what are your ideas on the problem?

Kind regards,
Dimitris

As far as I remember I had resized the storage spaces within 1709, but one of the latest updates has probably messed up with the resizing function.

I am aware of the other issues but nothing resembled this.
My best guess is that this is a bug since I have exhausted most of the possible solutions.

I already have this text with red letters under the powershell screenshot :)

For anyone reading this- I've OCR'd the text in red:

PS C:\Windows\system32> Resize-Partition -Size 37.1TB -DriveLetter h
Resize-Partition : Invalid Parameter

I had an idea that worked out just fine

I booted in Safe Mode and extended the pool to the available virtualdisk size












Now the volume has successfully resized to 59.9TB

Hope this will help anyone with the same problem

Always backup before such procedures!
