Hyper-V Damaged VHDX MBR

January 5, 2015 Leave a comment

So today was a fun day, one of our development office host servers had a storage issue this week and fried the volume where all the development virtual machines were running on.

I managed to fix the storage volume however I found a number of VM’s still would not start. The error indicated there was no boot volume.

To fix the issue and repair a Windows 2012 R2 Start-up issue I followed the below steps:

 

1. Put the Windows Server 2012 R2 installation disc in the disc drive, and then start the computer.
2. Press any key when the message indicating “Press any key to boot from CD or DVD …”. appears.
3. Select a language, time, currency, and a keyboard or another input method. Then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type Bootrec /RebuildBcd, and then press ENTER.

Issue:

When setting or amending a configuration setting in SCVMM 2012 R2 against a Hyper-V Clustered VM I got a error which looked something like

 

Error (2915)

The Windows Remote Management (WS-Management) service cannot process the request. The object was not found on the server (SERVER NAME)

Unknown Error (0x80338000)

This put the VM in the console into a failed state, the natural first action is to try and repair the VM, this generates another error which looks like:

Error (12711)

VMM cannot complete the WMI operation on the server (HOST Server Name) because of an error (MSCluster…….) The cluster resource could not be found.

the cluster resource could not be found (0x138F)

1.Logon to one of the host servers and from a Powershell session run:

2.Import-Module FailoverClusters

Get-ClusterResource -c CLUSTERNAME | where {$_.resourcetype.name -eq ‘virtual machine configuration’} | Update-ClusterVirtualMachineConfiguration

3.From VMM console refresh cluster

4.From VMM console repair VM

October 29, 2013 Leave a comment

Just had to extend a CSV volume in our Windows Server 2012 R2 cluster due to low available disk space that was alerted by SCOM.

The good news it was the same process as Windows Server 2008

1) Increase size of LUN on you storage.
2) RDP to current CSV owner
3) run diskpart from Command Prompt
3.1) rescan
3.2) list volume
3.3) select volume 4
3.4) extend
3.5) list volume
