Hi,
I have a 4 node Hyper-V cluster running Windows Server 2012 R2. I'm having a problem with one VM on the cluster dropping randomly with a 1069 event in Failover Cluster Manager (Cluster resource 'virtual machine <vm name> of type 'virtual machine' in clustered role '<VM name>' failed). I'm aware of at least 3 failures in the last 2 weeks, but can't find a trigger. It did seem (strangely) that it was occurring when running some PowerShell commands on the host (either Get-VM or Measure-VMResourcePool), but the latest drop there was nothing ran against the host.
The VM is running SQL on 2008 R2. I've tried the VM on different hosts (all the same spec) as the first time it happened I wondered if it was faulty memory module, but it has still dropped on that host. It's configured for static RAM with SQL being NUMA aware. The specs fit in a single NUMA node. There are other VMs on the same hosts and on the same storage and they don't seem to have any problem. I've tried removing the VM from the cluster and re-adding it. The hosts that I've tried hosting the VM on are not the owner of the CSV that the VM resides on. I have hardening applied to the hosts, based on CIS guidelines. I believe all recommended cluster and Hyper-V hotfixes are installed.
The event logs on the VM just show the last shutdown as unexpected.
On the host, I've ran a Get-ClusterLog (with -UseLocalTime) and found a few entries that look like they could provide useful info, but I haven't yet found any info on them. The failover cluster dropped the VM about 14:29 in these logs, but I've included some key info from before and after in case it helps:
