I'm working on testing a Hyper-V 2-node cluster for my employer, and have run into a problem. I suspect the problem stems from a reboot after installing some updates on the nodes and storage (which has led me to create a more stringent update policy for the cluster.)
The problem is that since the cluster has come back up, I had a VM that was "stuck" in a Pending state. So I began hammering at it trying to "unstick" it, finally going into the Dependencies tab for the VM, and removing the dependency for the Virtual Machine Configuration resource. This has led to my current problem.
Now, in the Services and applications section of the Cluster Manager, I have the following:
In the left-hand pane, I have the old VM still listed, with a red X over it. Clicking it displays <unavailable> for all the items in the Summary, and "Failed to retrieve the resources in this service or application." Attempting to delete this VM gives "Could not delete Services and Applications {VM Name}" and the details shows "The object has been deleted from the cluster."
If anyone could help me with the following, it would be appreciated:
- How do I get rid of the "Failed to load the item" and the "Single Client SQL Server" items?
- In the future when we install updates (manually, I'm not turning on auto-updating in any of the cluster devices) do weproperly reboot?
I'm thinking the answer to #2 might be to first, migrate all the VMs to one host, update the now unused host and reboot, then migrate all the VMs back to the now updated host and repeat. Then when updating the storage system, take the CSV offline, then reboot the storage array. Once it comes back up, online the array, then bring the VMs back online.
Thank you all!
