Storage Spaces not increasing the allocated Size in Thin Provisioning Storage Pool - error "Not enough space"

Hi,
I have a pool of 2 RAID SSD (a RAID1 3.25TB and a RAID5 24TB), with multiple thin virtual disks and volumes, everything worked ok until last week. We started getting the error "not enough space" when there is enough on the pool, the virtual disks and the volumes.
All physical disks are healthy and tried pool optimization, nothing worked!!!!

Hi there,

I would suggest you dig more into the Event viewer to get some insights about what is causing this issue so that we can start the troubleshooting. In general, start with the following steps:

-Confirm the make/model of SSD is certified for Windows Server 2019 using the Windows Server Catalog.
-Confirm with the vendor that the drives are supported for Storage Spaces Direct.
-Inspect the storage for any faulty drives. Use storage management software to check the status of the drives. If any of the drives are faulty, work with your vendor.
-Update storage and drive firmware if necessary. Ensure the latest Windows Updates are installed on all nodes.

The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.

Thank you for your answer,
I checked everything, all is good, firmware is updated, hardware is supported etc.
The showed a VSS error, but it is resolved now, and I'm still having the same problem.
