xDisk resource does not support resizing an existing partition

[nebffa]

If you do something like:

Configuration Server
{
    Import-DSCResource -Name xWaitforDisk -Module xStorage
    Import-DSCResource -Name xDisk -Module xStorage

    Node "perftest01"
    {
        xWaitforDisk Disk2
        {
            DiskNumber = 1
            RetryIntervalSec = 60
            RetryCount = 10
        }

        xDisk DVolume
        {
            DiskNumber = 1
            DriveLetter = 'D'
            Size = 1GB
        }
    }
}

Server
Start-DscConfiguration -Force -Verbose -Wait -path .\Server

followed by

Configuration Server
{
    Import-DSCResource -Name xWaitforDisk -Module xStorage
    Import-DSCResource -Name xDisk -Module xStorage

    Node "perftest01"
    {
        xWaitforDisk Disk2
        {
            DiskNumber = 1
            RetryIntervalSec = 60
            RetryCount = 10
        }

        xDisk DVolume
        {
            DiskNumber = 1
            DriveLetter = 'D'
            Size = 10GB
        }
    }
}

Server
Start-DscConfiguration -Force -Verbose -Wait -path .\Server

(note that the only difference is the size specified for DVolume)

The DSC run will fail:

I'll look into this once #53 is complete.

[PlagueHO]

This one is possible but I think it will require implementation of a "Destructive" switch on the resource. The switch would allow destructive adjustments on the disk to be performed.

It is related to #50 and #54 if a reformat would be allowed.

Hi @PlagueHO , are you still looking into this? If not I would like to take over this one as I also have customers who encounter this issue. Additionally, I plan on adding a parameter like FillRemainingFreeSpace since this is also a very common scenario.

Hi @nyanhp - I'm creating some new resources (xDiskEx, xPartition and xVolume) that allow far more control over disk provisioning. See #81. xDisk does not handle many more complicated disk partitioning scenarios. But I've not had time to complete these (and I won't for another few weeks).

That said, if you want to get xDisk to enable partition resizing, then I'm all for it! 😁

I've just got lots of reviews backed up so haven't had much time to put into new resources or features. But if you do have the time - then it is greatly appreciated!
