Running diagnostics to check cluster health is a valuable tool. Failures can be confusing. Some failures to be aware of:

  • Initial diagnostics of the head node might fail indicating the management service is not running. Many times the test is run too soon and the service is now running. Clear the error and rerun to verify the service is running.

  • The SOA test may fail. If you do not designate a broker node, this test fails. Do not run this test if you are not using SOA.

  • Windows Update check might fail. If you do not perform Windows Updates after the installation, this test fails. Initiate a Windows update, or schedule an update from the maintenance section on the compute node templates. Take the nodes offline and select Maintain to run the updates.

  • The DNS test might fail, indicating the private node is communicating through the head node. If the private node is not on the public network, the node's DNS entry should be proxy'ed through the head node and not show up in DNS. Sometimes a DNS entry will appear with the node's private address. These are incorrect and can be deleted.
