    Storage Spaces + Pool Capacity


    I have 2 storage spaces set up. I am a bit confused when it comes to one of them as it is not utilizing the full pool capacity after adding a disk. Does anyone know the command line commands to expand it to utilize the full pool capacity? I have tried to Optimize to no avail.

    Understanding Storage Spaces capacity descriptions

    I have a Storage Spaces array in Windows 10 consisting of 7 SATA HDDs ranging from 3TB -> 8TB each (-edit- for completeness, those drive capacities are: {3, 4, 4, 4, 4, 8, 8}).

    I'm trying to understand the Storage Spaces capacity values, shown below:


    Storage Spaces + Pool Capacity IuI6y.png


    The section above the drive Name & Letter makes sense in isolation:

    • 15 TB
      • defined size, with thin provisioning allowing it to exceed actual
        available capacity
    • Using 14.6 TB pool capacity
      • the actual available configured capacity

    And the 31.8 TB "Total pool capacity" makes complete sense as the sum of the actual disk capacity from each drive.

    But...

    1. Why is only 14.6 available?
      • I've defined my size as 15 TB
      • It says I have 17.2 TB available
    2. What's the relationship here of the 22.5 TB "Including resiliency"?
    3. What is my actual real max configurable usable capacity?
      • I expected to have around 20 TB (66% of 32) - so I'm guessing it's actually only 17.2, but then see question #1

    Storage Spaces capacity error

    Hi,

    I am using Storage spaces in Raid 5 (parity).

    Storages spaces is telling me that my capacity is full and I need to add more drives. However, in 'This Pc' (my computer) it is telling me I still have over 7.5 tb available?

    I have checked the data in my pool and it confirms that i should still have 7.5tb available.

    Why is storages spaces telling me otherwise? Is it wrong? Is it malfunctioning? Have I done something wrong?? Can i correct this???

    Details:

    OS - Windows 10 Pro 64-bit

    8x 3tb WD Green harddrives (data) - Raid 5 (parity)

    1x 120gb Kingston SSD (OS)

    Storage spaces indicating:

    Pool capacity 21.8 tb

    Using 21.5 tb

    This Pc indicating:

    Capacity 21.7 tb

    Used 14.2 tb

    Free 7.51 tb

    I have checked the size of the data in the pool and it is matches with what 'This Pc' is reporting. Why is Storage spaces saying otherwise?

    Please help!

    Much appreciated! Storage Spaces + Pool Capacity :)

    Storage Spaces + Pool Capacity

    Storage Spaces capacity error

    Hi, Thanks for your response.

    But this does not explain why 'storage spaces' says my pool is full and 'My PC' says i have 7.5 tb of space available?

    'My PC' IS correct, 'storage spaces is incorrect. But 'storage spaces' will not let me add any new files/data.

    I did run Disk cleanup like you suggested but there were no files to clean in the 'storage spaces' pool.

    The pool is only used to store media files. Not OS.

    Please help x
