Hi,
- Why can the storage space exceed the size of the storage pool it is located in?
The size of the storage space is the virtual disk size that you can see in Disk Management, which means you can write 30TB to the storage disk at most. Since the storage space is thin provisioned, not all the space is allocated in the storage pool when the storage space is created. In your case it's currently 4.84TB and it will increase as more data is written to the disk.
- The excess capacity does not exist physically. Will there be any loss if files are stored?
If you run low on the available capacity of the storage pool, you will be informed by the OS so that you can simply add more disks to expand the storage pool and there is no need to modify the existing storage pool.
- After I set the storage space to 30TB, why does Drive D still show 7TB?
Open Disk Management and see if there is any unallocated space on the storage space disk. If yes, right click on the D drive and select Extend Volume to add the unallocated space to the volume.
- What does the maximum storage pool usage rate mean?
The resiliency type of the storage space is parity so you need additional space in the storage pool for resiliency.
