Environment: Azure, Windows 2012 R2 VMs.
I've created a Storage Pool of 3 disks (VHDs), striped, a Virtual Disk on top of it, and a volume. Then I've stopped this VM, detached these VHDs and attached them to another brand new VM. When second VM started, the Storage Pool and Virtual Disk appeared automatically, and even a volume was automatically created (with different volume letter, but anyway).
So, where is information about Storage Pool is stored? On one of the disks, on all of them (duplicated) ?
