# Create cluster-volumes

So, the only thing that's left is to create a cluster volume on the Storage spaces direct pool of clustered disks. I used the cmdlets presented [here](https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/create-volumes).

**Warning**: Don't create a 1TB volume ;) adjust your size

```
New-Volume -FriendlyName "Volume1" -FileSystem CSVFS_ReFS -StoragePoolFriendlyName S2D* -Size 1TB
```

Here is me executing the cmdlet, on my DC.

All in all, this is how your pool should look like in the failover cluster manager.

If you were wondering where that **S2D\*** came from in the cmdlet. So did I. It was only afterwards I found out where you can get the Pool name.

Mind your cluster capacity! It's very nice to show the complete capacity, but bear in mind that in a 2-node cluster Storage Spaces direct is set to "mirroring". Just like [Microsoft KB](https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/plan-volumes) says:

> The only option for clusters with two servers is two-way mirroring. This keeps two copies of all data, one copy on the drives in each server. Its storage efficiency is 50% – to write 1 TB of data, you need at least 2 TB of physical storage capacity in the storage pool. Two-way mirroring can safely tolerate one hardware failure (drive or server) at a time.1

All in all, have a good look around before heading to the next part.
