Online Re-sizing Of Hyper-V Virtual Disks in Windows 2012 R2

Hello

    As we Talked before,  about the advantages of  Microsoft Windows 2012 R2
    so now you can Re-sizing the volume of your VM online :)

 


Remember :  VM volume has to be VHDX otherwise you will not use it

• and it support Generation 1 & 2
• VHDX can't be shared 
• you can Extend and Shrink the virtual disk 
• VM should be  attached to a vSCSI controller
• This feature can leverage ODX for speed when available

If there is no UN-allocated disk space the option to shrink the VHDX won’t even show

which is mean you’ll first need to shrink the volume inside the virtual machine if all disk space has already been allocated
