  • One node in the clustered structure is non-responsive

    Hi,

    I am recently encountered with the problem of Virtual Servers being non-responsive at times. after the troubleshoot i have identified that it is those servers which is under one Node is what becoming non-responsive. So for the time being i have moved all my virtual OS into another node (Node1), I would like to know why one node is performing perfectly and another is not? I have tried chkdsk, windows update etc but no use. There's no lagging or any other issues when accessing the Node2 which is causing problem when hosting virtual OS into it.

    My network details as follows:

    2 identical servers as Node1 and Node2

    the servers are clustered using clustering service and the hardware is Dell equallogic

    Both the nodes are Windows 8R2
    Virtual OS created using Hyper V and all the OS are windows 8R2

    Regards,

    - Go through the event log and see if there are any errors.
    - In Failover Cluster Manager, see if there are any errors reported.
    - Run the cluster validation tests (note that you can't do the storage tests because it's in use)
    - Have you installed the Hyper-V and Cluster patches?

      Yes, i have updated the server into the latest patches.

      Hyper-V is already installed and i had 2 virtuals nodes running on this Hyper-V host for about one and half years. Only recently i started facing this issue.

        Since you're running Hyper-V and Failover Clustering there are patches you should install that do not come through Microsoft Update. The two links I provided list all the pertinent updates for 2008 R2 and whether they're available as a hot fix download or through Microsoft Update. Go through both links and install the recommended patches.

        Yes, I realize you have Hyper-V and Failover Clustering installed. You should still go through the logs and run the validation tests.

          Thanks for the reply ( and sorry for pestering)

          I did the validate this cluster and i am getting the below error message, other than every other test in the validate this test is complete and green in color

          ( Copying the error message here)
          =======================
          Validate Disk Failover

          Failed to write file data on cluster disk 0 partition 1, failure reason: The disk structure is corrupted and unreadable.

          ======================
          But in this situation, the node which is mentioned above ( Node1) is working perfectly fine and i am having issue with Node2.

          Can you please advise?

            The disk failures are to be expected. (as I noted)

            I hate to belabor this but can you confirm that you downloaded and installed the Hyper-V and failover clustering patches from the two links I provided?

            Are these Dell servers?
            If so, download and run the SUU (software update utility 7GB+ ) to update the drivers and firmware.

            I would also run the hardware diagnostics on the node that has issues. Could be bad RAM or CPU or any number of other components.

              Depending on the age of the servers they MAY have the Dell LifeCycle controller that can do all that for you.

              We have it on our R710 servers which are circa 5 - 6 years old.

                    Please don't bump your posts - members give up their free time to help out and there are not always the right people on line at any point. If you need more urgent support, raise a case with Microsoft Product Support Services who have teams of engineers waiting to leap into action (all major credit cards accepted )

                    Are you in a position to format and reinstall the OS on the problem node to see if it cures things?

                        No, it means to wait and let other people reply (unless you have new information to tell us). In all forums it is bad manners to post something and then (minutes, hours or even days later) to post again asking if anyone can help you.

                          Have you tried evicting the node from the Cluster and re-adding it? You may have to consider reinstalling if you still have an issue and have reviewed logs of Dell and MS.
