    I know that storage spaces doesn't automatically rebalance when you add / remove drives. Is there any way through powershell to manually rebalance?

    I don't know if it matters but i'm using ReFS in a parity configuration.

    If it isn't possibly what do you do when you run out of space on your pool and add a new drive? If you can't rebalance then you would still be out of space.

    So the short answer is that it's not possible to re-balance in any
    practical sense, except perhaps by migrating all data to a new storage
    space or similar?

    It seems so. As you said it is also discussed a lot in that thread.

    To all googlers who spend hours searching the net for a solution to the rebalance problem in a parity configuration (Like me ;). At the moment (January 2013) there is no Microsoft tool that does the job (includes PowerShell commands). To ensure that all hard drives can get the same level, you have to copy all the data once, and then delete the originals. That takes a while, but is currently the only way.
    Regards

    Thanks for all the research. Not totally surprising, but Storage Spaces
    really is a v1 product, it'll probably just be a matter of time until
    there's a better toolset for this.

    Unfortunately for me, I AM surprised. Jebus Christ. I've been giving Microsoft too much credit. I was expecting it to work, at a minimum like Drive Extender in WHS. It's nothing like Drive Extender and is a pain in the ass for me right now. I was running out of space so I bought a 3TB drive and added it to the pool. Now the entire pool is offline, because it's expecting another disk to match the 3tb that was just added, supposedly, it's all out of space...

    and there is no way to REMOVE a disk from the storage spaces control panel. This is all under Win8 Pro. I'm not using the server edition. Publish the limitations so that people can make wise decisions before they commit.
