I have a Windows Storage Spaces Mirror Pool compsed of 2 8TB drives.

I have been running it without problem until the moment when I forgot to turn on of the drives on and I have added some new data to the pool.

From this moment the pool shows "Reduced Resiliency, check the physical drives section". One of the drives shows: "Error; consider replacing". Individually although both drives work correctly.

Is there a way to repair the pool?

I have tried the AI generated answer with these results:

Repair-VirtualDisk : No MSFT_VirtualDisk objects found with property 'FriendlyName' equal to 'WD Elements 25A3 USB Device'. Verify the value of the property and retry.

Repair-StoragePool : The term 'Repair-StoragePool' is not recognized...

Install-WindowsFeature -Name Storage-Services

Install-WindowsFeature : The term 'Install-WindowsFeature' is not recognized...

Thanks

    To repair a Storage Spaces Mirror pool with Reduced Resiliency, you can try the following steps:

    1. First, make sure both drives are connected and turned on.
    2. Check the health status of the drives using the Get-PhysicalDisk cmdlet in PowerShell. If one of the drives shows an error, consider replacing it.
    3. If both drives are healthy, you can try running the Repair-VirtualDisk cmdlet in PowerShell to repair the virtual disk. This cmdlet repairs the resiliency of the specified virtual disk by rebuilding the data on the failed or degraded physical disks. Here is an example command:
    Repair-VirtualDisk -FriendlyName "MyVirtualDisk"
    
    1. If the repair is unsuccessful, you can try running the Repair-StoragePool cmdlet in PowerShell to repair the storage pool. This cmdlet repairs the resiliency of the specified storage pool by rebuilding the data on the failed or degraded physical disks. Here is an example command:
    Repair-StoragePool -FriendlyName "MyStoragePool"
    

    If you do not have the Storage Spaces-specific cmdlets in your PowerShell, you can install them by installing the Storage Spaces feature. Here is an example command to install the feature:

    Install-WindowsFeature -Name Storage-Services
    

    Note that you may need to restart your computer after installing the feature.
