Challenge
This article describes how to fix the warning/error “ConfigStoreRootPath cluster parameter is not defined” appearing in the following situations:
- When attempting add a Windows Server 2016 Hyper-V cluster to the Veeam Backup & Replication Console.
- When attempting to backup a VM with a shared virtual disk located on a Windows Server 2016 Hyper-V cluster.
Cause
In Hyper-V 2016 Microsoft implemented a possibility to share a virtual hard disk (in .vhdx or .vhds format only) between two or more VMs and use that virtual hard disk as shared storage when building guest clusters.
When adding a Windows Server 2016 Hyper-V cluster to the Veeam Backup & Replication Console, you must decide where to store metafiles created during the backup process of the VMs from the shared virtual hard disk (i.e. information about snapshot groups, etc.).
By default, the metafiles location is not defined, so you need to define it manually.

Solution
To check the existing configuration run the following PS command on any node of the cluster:
Get-ClusterResource "Virtual Machine Cluster WMI" | Get-ClusterParameter ConfigStoreRootPathBy default, “value” points to a cluster volume (e.g. C:\ClusterStorage\Volume1).
Please note that this value can be set only once. After the value is set, it cannot be changed.
Please note that this value can be set only once. After the value is set, it cannot be changed.
First, create a folder on that volume, and this folder will act as the meta files location. The folder should be available to all members of the cluster. (e.g. C:\Clusterstorage\Volume1\Hyper-V\Shared)
Then, specify the path to the newly created folder with the following commands:
Then, specify the path to the newly created folder with the following commands:
$path = "C:\ClusterStorage\Volume1\Hyper-V\Shared"
Get-ClusterResource "Virtual Machine Cluster WMI" | Set-ClusterParameter -Name ConfigStoreRootPath -Value $path
The cluster now can be added to Veeam. If the cluster had already been added and the backup failed with the error in question, re-run the backup after setting the value.
