Remove-StoragePool S2D - Access Denied

Luigi Pandolfino 20

We had the need to reinstall an Azure Stack HCI cluster from scratch.
When we got to creating volumes WAC wouldn't let us erase the disks. We then tried to delete the previous volume with the Remove-StoragePool and Remove-VirtualDisk commands but we had these errors:

Remove-StoragePool : The storage pool could not complete the operation because its configuration is read-only.

Remove-VirtualDisk : The storage pool could not complete the operation because its configuration is read-only.

We then tried running the Set-StoragePool -IsReadOnly $false command with this result:

Set-StoragePool : Access denied

Do you have any idea how to solve it?

Check if the storage pool is in a read-only state by running the following command in PowerShell:

Get-StoragePool | Select-Object IsReadOnly

If yes, run PowerShell as an administrator and try running the command again.

If the above steps do not work, you can try the following:

Check if the storage pool is in a healthy state by running the following command in PowerShell:

Get-StoragePool | Select-Object OperationalStatus

If the output shows that the storage pool is not in a healthy state, we might need to troubleshoot the issue further. Share the results and we can further investigate.

Check if there are any other processes or applications that are accessing the storage pool. If there are, try stopping them and then try running the command again.

Try these and let me know the results.

Hi,

The storage pool is in a read-only state because the cluster is not available to bring it online. This is a protection mechanism to prevent changes to the storage pool when it is not in a healthy state.

If you are looking to clean the disks and create a new storage pool, you will need to do it manually using the steps listed in this link - https://video2.skills-academy.com/en-us/windows-server/storage/storage-spaces/deploy-storage-spaces-direct#step-31-clean-drives.

After cleaning the disks using the above script, the storage pool metadata will be completely removed, and the disks will be ready to recreate a new storage pool.

Hope this helps!
