  • VM - This service or applications have no resources

    One of my VM's in my infrastructure is giving me this error after I had an unexpected shutdown on my blade.

    When I open it from the FAILOVER CLUSTER MANAGER it is giving me the error:

    This service or applications have no resources


    Attached you will find what normally is displayed on a good VM and what is showing now on this particular machine.

    Can someone help me with this? and how I am going to bring back the resources for this machine?

    Thanks very much!

    It might be easier just to recreate the VM and attach the existing VHDs to the new VM. When you do this you'll have to reconfigure the IP settings for the server since it will see the NICs as different hardware.

      Thanks very much for your reply.

      A related question, I have a snapshot linked with that current VM.

      Will I be able to link the new VM to the snapshot or will it be deleted if I delete my current VM?

      Thanks.

        I don't think it's possible to associate the snapshot with the new VM. You will, however, have the differencing disk from the snapshot (.avhd) available to you. So you could still choose which spot you'd like the VM to be at.

        If you want the current state then I would merge the differencing disk into the parent. If you want the snapshot then you can just discard the differencing disk.

        BTW - is this a production VM?

          Ok thanks.

          No, currently the server is not used but is going to be a production server in the near future.

          By any chance, just for my knowledge.... why do you think this happened?

          Thanks.

            Hard to say without know what was done, how things are configured, and what transpired.

            You can look through the server logs to see if there's any indication of what happened.

            The reason I was wondering if this VM was in production is because you really shouldn't do snapshots on production VMs.

              Thanks Jeremy.

              Do you mean its not good to take snapshots of a VM which is constantly being used?

                Re: VM - This service or applications have no resources

                Correct. Taking snapshots creates an avhd (automatic VHD) file which is a differencing disk. Differencing disks are dynamically expanding and don't perform as well as fixed VHDs. Also, the differencing disks will continue to grow over time and will continue to consume disk space. They can grow to be several GB, upto the logical size of the parent VHD. If you take multiple snapshots the problem is compounded with multiple differencing disks. And then, if you decide to delete the snapshots you won't regain the space until you shutdown the VM and allow it to merge. Depending on the size of your differencing disks this could take several hours... or more!

                So that is why it's not recommended for production use.

                  To ensure that your VM is using a fixed disk, when creating the VM, point it to the fixed disk. If you choose to create a VHD when creating a VM, it will be a dynamically expanding one.

                        See step 6:
                        http://technet.microsoft.com/en-us/l.../dd759216.aspx

                        If you're still having trouble you can always delete the VM and then use Failover Cluster Manager to create it.
