How to create Windows simple storage pool?

  • 772

In Windows Server 2019, I am trying to create a simple storage pool with 6 disks using Powershell. The total size should be about 42 TB, but it creates a pool of only 1.23 TB. The rest is still part of the primordial pool. Here is how the disks look before.

PS D:\> Get-PhysicalDisk | Where Size -eq 7681501126656

DeviceId FriendlyName               SerialNumber                             MediaType CanPool OperationalStatus HealthStatus Usage          Size
-------- ------------               ------------                             --------- ------- ----------------- ------------ -----          ----

Here is the command to create the pool

PS D:\> $PD = (Get-PhysicalDisk | Where Size -eq 7681501126656)
PS D:\> New-StoragePool -FriendlyName NVMePool -Verbose -PhysicalDisks $PD -StorageSubSystemFriendlyName "Windows Storage*" -ResiliencySettingNameDefault Simple

FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly    Size AllocatedSize
------------ ----------------- ------------ ------------ ----------    ---- -------------
NVMePool     OK                Healthy      False        False      1.23 TB        1.5 GB

And the results

PS D:\> Get-StoragePool

FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly     Size AllocatedSize
------------ ----------------- ------------ ------------ ----------     ---- -------------
NVMePool     OK                Healthy      False        False       1.23 TB        1.5 GB
Primordial   OK                Healthy      True         False      42.79 TB       1.24 TB

  1. I figured it out. These disks had existing partitions from a previous application. So the storage pool was only using the first partition of each. The solution is to wipe each disk with diskpart clean
