HyperV - Expand Disk - Greyed out

Posted on 2011-10-27

I used HyperV "edit disk" to "expand" the VHD and it did.  When the VM came online and I go into disk manager I see the extra space to the right of my volume, however when I select it, the option for Extend Volume is grey.

This just doesn't seem right to me.  What am I dong wrong?

    Look in to this Microsoft Article:

    Take note on the requirements for the extend command section, which applies for both methods of configuration, command line and disk management window

    also here is a link of full comparison between the two methods and list of Diskpart commands:

    hope it helps

    from my experience, yes it is better to do it through Diskpart, but as i said you need to make sure that none of the requirements listed on the article conflict with your disk configuration.
