Storage Spaces Direct - New Volume on Virtual Disk

Question

Is it possible to add a new volume to an existing virtual disk? The reason behind this is, that i would like to set certain values like interleave for the virtual disk. But right now you can either create a new virtual disk but can't add a volume to it or create a volume which creates a virtual disk with default settings.

storage spaces direct operates lower than volume level, so you can't add a volume. Microsoft's most detailed how-to guide for now is here: https://technet.microsoft.com/en-us/windows-server-docs/storage/storage-spaces/add-nodes?f=255&MSPPError=-2147217396

Also, may I wonder what is the reason to set additional parameters? I'm learning s2d myself so would be glad to know if that provides any performance perks.

Thanks for your answer. One of the reasons was that I like setting the interleave value to 64kb since I use HyperV workloads. But this is not possible with just the virtualdisk or volume command. – Rikuto Nov 29 '16 at 19:40

After doing some testing I kind of figured it out. The key is to work with storage tiers. New-StorageTier has almost the same options as New-VirtualDisk. When you use the storage tier parameters from the New-Volume command, it creates a virtual disk using the storage tier values instead of default ones.
