5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Helped take backups using Veeam. As we expected, the ncc Kerberos check indeed showed Kerberos authentication failure. The computer object representing the NOS cluster was indeed present in their AD. It's likely that the group policy configured for the OU had some password-specific setting that caused authentication to fail. As a resolution we unjoined the NOS cluster from AD using the hidden ncli command. Then we tried joining the NOS cluster back to their AD using the GUI. But this step failed saying "the server cannot handle directory requests". Since we were not sure why this message is showing up and since we wanted to get the customer quickly take backups of their production VMs using Veeam, we resorted to a 2-step cli process. (1) First we created a computer object in AD using the New-NosClusterComputer Powershell command. (2) Then we used hidden ncli cluster join-cluster-no-ad to configure the passord in NOS. Then after clearing the (stale, cached) Kerberos ticke
Hello Domain-joining the NOS cluster should not require reboot of any of the cluster components. So if you need help with this, please file a support ticket with Nutanix and we'll help to get the backups going.
Hello , If VSS backups were working properly earlier and had suddenly stopped working, couple of things could have happened: (1) The time in the CVMs of the Nutanix cluster could have gone out of sync with the AD causing Kerberos authentication to fail. (2) The computer object representing the Nutanix cluster in AD/DC could have gotten deleted or disabled or could have had it's password reset. If you are running NOS 4.5, running ncc will quickly point you to the problem. Even if you are running a older NOS release, please run ncc. You can also try using diskshadow from any of the hosts in the cluster to isolate the problem.
