Hyper-V - Unable to edit virtual disk

I am looking for some assistance with my two Hyper-Vs please .

I have a 2 Hyper-v hosts, running Windows 2008 R2.  HV-01 has 4 VM’s and HV-02 has 5 VM’s.

I needed to extend a drive on a guest on HV-01, I shut the guest server down,  then on Hyper-V manager I went to: settings > hard drive > edit
I then get an error stating: Unable to edit virtual disk (Screen grab attached).

Unable to edit virtual disk
If I select the option to inspect, I get: An error occurred attempting to connect to the virtual disk managementAn error occurred attempting to connect to the virtual disk management service on computer localhost.



I checked each of the VM’s on the HV-01 machine and the same error occurs when I selected the “Inspect” option.  When I checked the VM’s running on HV-02 there is not an issue, both of these servers are identical running a failover cluster service with a SAN.

I have restarted the services connected to the Hyper-V’s, the permissions of the services are the same  on each host to nothing has expired on any account used.

If I reboot the host will all of the guests automatically move onto the HV-02, I think this has been done in the past but can’t be sure if the VM’s were all taken offline first.

Given the re-boot does not rectify the permissions issue, does anyone have some ideas on where to go with this?

Many thanks in advance.

check the permissions on the folder that holds the virtual machines, are you running as a domain administrator?

Hi

This was not a permissions issue, the same access and administrator account was used across all the VM's on the SAN.

I closed down all VM's on the HV-01, rebooted the host and brought the VM's back online and the permissions error on both edit and Inspect was resolved.

Why it happened in the first place I have no idea, maybe I will need to schedule a reboot on the hosts once a month to ensure it does not happen again.

Thanks though for getting back on this :-)

A reboot of the server resolved the permissions issue.
