Hyper-V 2016: Unable to expand VHDX in windows 2016 cluster and while powering down VM, it gets stuck in stopping state

    Discussão Geral

  • Hello, 

    I am experiencing an ongoing issue with Hyper-V 2016, when I try to expand a VHDX via Failover Cluster Manager or Hyper-V Manager the expansion does not complete. Furthermore, when I attempt to stop the virtual machine the machine hangs at stopping and becomes unmanageable, this is happening on Hyper-V 2016 and the virtual machine is running Windows Server 2016

    Has anyone else experienced a similar issue with Hyper-V 2016?

    Thanks!

  • Yep can confirm this too for HV-Cluster 2016 - but at this time only if the running vm is also SRV 2016 !

    After two days it locks down the cluster - pay attention guys!!!

    work around in my case is to do it offline aka power down!

    //EDIT

    WORKAROUND / 1st Aid

    If you expand the vhdx and the process never finish, DONT STOP IT !!! Leave it as it is, evacuate the Node and just reboot it - otherwise your cluster locks down like mine did and u have to reboot the whole cluster, forced with pstools!

    After reboot you should be able to expand it (in my case it doesn´t matter if the machine is running or not!)

  • Hi, guys!

    We got same issue (Windows Server 2016 Cluster and standalone, VMs with 2012 R2 guest). Is there any news?

    Btw what backup software you are using? Does it use CBT/RCT? And what size of VHD you are expanding (more than 2 TB)?

  • Yep, I'm getting the same issue here on a Windows Server 2016 Hyper-V cluster.  

    Most of the time the disk expansion operations work fine.  I've done a total of about 15 operations so far and on 3 occasions it has locked up.  After you hit finish on the Edit Virtual Hard Disk Wizard, the progress bar never advances even after waiting 24+ hours.  As others have said, the only fix seems to be to reboot the host.
