Hi,

I have got a 2-node failover cluster on Windows Server 2019.

I have shared 3 CSVs on these nodes.

The cluster is "working correctly" when I have all my VMs on one node, but when I try to migrate some VMs on the second node I have got problems because this node "dies" and stops VMs.
One VM can be on the second node others cannot.
That's what I have when I try to migrate VMs between nodes:

It's a network issue?

    Hi

    can you run "Validate Cluster" to run a report against the cluster health? This will show any issues that exist and will pinpoint any issues that exist on the second node

    Thanks

    Hello,
    As mentioned, try to run validation on your cluster and check if report contains any errors. In addition, the following article might help with troubleshooting:

    What are you using as a shared storage? There might be an issue with your network configuration. The following articles might be helpful:
