Storage Spaces Direct Cluster (Validation fails on port 3343 over the Mellanox NICs)

Hi Everyone,

I am building a 4 node storage spaces direct cluster running Server 2022.

Each node has two (dual port) NICS. Intel 10gb and Mellanox 100gb.

When running the cluster validation test, is it normal to see errors on the mellanox NICs for port 3343?

My config is:

intel nic0 and nic1 attached to a SET vSwitch (vnics for management, cluster, livemigration)

mellanox nic0 and nic1 for storage

The report is all green except for this one error. It's not firewall, as i've checked the ports are allowed.

Thanks!!

    Hi there,

    Some points to note here.

    • Patch the server with all Windows OS Updates and restart it.
    • Try disabling the Antivirus on both the servers and give it a try.

    Here is a thread as well that discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.

    @Glen Harrison any update here? I ran into same issue with a new deployed Server 2022 cluster (4xDell AX740xd, SMB-Traffic via QLogic QL41262 over Cisco N9K-C93180YC-EX-switches).

    When we started patching last week (due to april-patchday) it took 7 minutes after first node had rebooted until it rejoined the cluster. In Failover cluster manager it throwes error

    Cluster node 'HYPERVISOR01' failed to join the cluster because it could not communicate over the network with any other node in the cluster. Verify network connectivity and configuration of any network firewalls.

    followed by

    Cluster failed to start. The latest copy of cluster configuration data was not available within the set of nodes attempting to start the cluster. Changes to the cluster occurred while the set of nodes were not in membership and as a result were not able to receive configuration data updates. . Votes required to start cluster: 2 Votes available: 0 Nodes with votes: HYPERVISOR02 HYPERVISOR03 HYPERVISOR04 Guidance: Attempt to start the cluster service on all nodes in the cluster so that nodes with the latest copy of the cluster configuration data can first form the cluster. The cluster will be able to start and the nodes will automatically obtain the updated cluster configuration data. If there are no nodes available with the latest copy of the cluster configuration data, run the 'Start-ClusterNode -FQ' Windows PowerShell cmdlet. Using the ForceQuorum (FQ) parameter will start the cluster service and mark this node's copy of the cluster configuration data to be authoritative.  Forcing quorum on a node with an outdated copy of the cluster database may result in cluster configuration changes that occurred while the node was not participating in the cluster to be lost.

    In my host-based-firewall-logs, i noticed:

    DROP TCP 10.100.0.10 192.168.100.10 51199 3343 0 - 0 0 0 - - - SEND 13592

    which is weired because 10.100.0.10 is my management-ip and 192.168.100.10 is SMB-A-network. Why does the management-network try to communicate via SMB-A-network which is unrouted?!

    Cheers
    Miranda
