Storage Spaces (extending storage pool)

Question

Hi

I added another x2 set of 5Tb drives to my Windows Server, which is recognised at 5Tb each.

I want to extend my current storage pool, when doing this (i.e. selecting both disks) it only lists 2Tb total capacity for each disk (i.e. a total of 4Tb instead of 10Tb)

I am trying to understand why I cannot use the full capacity of those drives.

Hello

It looks like you've run into an issue where the storage pool doesn't recognize the full capacity of a newly added drive. Now that you've resolved this issue by rescanning, here are a few things to check if you run into the same issue again:

File System Limitations: Ensure that the file system you are using supports the full capacity of the drives. For instance, NTFS can support very large volumes, but there are still limits depending on the Windows version you are using.

Storage Pool Configuration: Check the storage pool configuration to ensure it's set up to accommodate the full capacity of the drives. There might be settings or configurations that need to be adjusted to recognize the additional space.

Drive Format: Verify that the drives are formatted correctly and that no partitions are limiting their capacity.

Metadata and Reserve Capacity: There could be metadata or reserve capacity that is taking up space. Some systems recommend reserving the equivalent of one drive's worth of capacity for overhead.

Physical Disk Health: Ensure that the physical disks are healthy and properly connected. Sometimes, issues with the disks or their connection can cause the storage pool to misread their capacity.

Software Updates: Make sure that your Windows Server is up to date with the latest patches and updates, as there might be fixes related to storage pool issues.
