Shrinking a spanned volume

Hi guys,

I currently have a Windows 2008 R2 server (VM) which has 6x 2TB dynamic disks which are spanned to create a volume of 12TB.

Currently only 1.2TB is in use so I want to shrink the volume to 3TB to allow for growth.
If I go through the GUI shrink wizard to make it 3TB, will it mean that I can remove 4 of the 2TB disks? or will that 3TB be split across all 6 disks?

I want to be able to use 8TB for another server, so just wondering if this is going to work, or whether there will be data loss, or other complications.

If it is as simple as shrinking to 3TB, and then deleting the unused disks, I can then resize the disk in the VM properties from 12TB to 3TB without any issues? (ESXi 4.1)

Copy out your data and reconfigure the drives the way you want them.
These dynamic drive configurations are always instable in case when you want to repartition the structure.
Also, I recommend you getting a good RAID controller and building normal hardware RAID instead of using dynamic software RAID configuration.

This will take quite a bit of work to do but it can be done.

You will need to make an image of the drive with a good imaging software such as Acronis or Paragon.

Once you have the image made you should be able to then pull the disks you want out and then erase the existing drives and create a new spanned volume with the existing disks and then image the drive with your old data.

Thanks guys.
The storage team will use this method.
We will add another separate lun and copy all data to the new size.
