hyper-v fails when attaching more disk to VM. The VM won't start and generates an error
- by CasperDK
I'm lost at what to do about this:
Hi...
System: Windows 2008 R2 Hyper-V farm running with failover cluster with a EVA 4400 as backend.
When I attach a new disk to a VM it fails when I try to start it.
If I move the VM to another, say node 1, I can add the disk and I can get them to start.
If I move the VM back to node 2 where the problem arose and the VM is running, I get an error during live migration and the VM fails back to node1 where it did run...
So it's like there is something wrong with Hyper-V on node 2 and not node 1. Also node 3 has the same issue.
Restarting the nodes is NOT an option since I will have this problem again at a later time AND because not all the VMs can run on node 1 which means my client company will experience downtime on the VMs not running on node 1.
Any fix for this? An update I have missed perhaps? It has been two years...
Here are the errors:

In the Hyper-V logs I found some more errors:
In the hyper-v VMMS logs I have this:
