Wizard Validation Failover Clustering - System Configuration

Question

Wizard Validation Failover Clustering - System Configuration

lra 86

Hello

I have the following drawback, we are creating two hyper-v clusters with two nodes each cluster.

When executing the cluster validation wizard, all the categories of the wizard go success, but the system configuration indicates a warning, attached image:

It refers to pending updates and asks to restart both servers. I have already restarted the servers, however the warning continues to appear.

Investigating a bit in the warning message, they say that it is because the server does not have communication with the windows update servers. The server has no internet connection, it has a proxy configured.

However, I would like some support in validating what can be done in this case.

With this warning message in the cluster validation wizard, can I create the cluster without problems?

Hi @lra ,

You can create the cluster if you have warnings only, not if you have errors.

The QFE error may appear if a proxy has been configured incorrectly, if you want to get past this you could remove the proxy configuration during the creation of the cluster and reapply it after the cluster has been created.

Regarding the pending updates, it is a fairly common one, I wouldn't worry much about that one, it's not going to do any harm really.

Hello,

Basically the proxy was not previously configured and in the same way the QFE warning appeared, I proceeded to configure the proxy in the browser and it also continues to appear.

Then I can create the cluster without problems, since the warning does not represent any risk.

Yes these are just warnings, you should really only worry about errors.

Hello,

Would it be a good idea to configure the proxy in the etc / host file?

Yes you can, the purpose of the hosts file is simply so that your computer can map a connection between an IP address and a domain name, in case the DNS would be down.

Ok ok, I would put the proxy ip along with your domain below these two items

Yes you can use the commented examples (localhost) ones :-)

Hello Leon,

Configure the etc host file with the ip and hostname of the proxy, but the wizard keeps throwing the same error.

Any other recommendation you can give me for this case?

The hosts file will likely not help with the proxy problem, the proxy configured in the Internet Settings should be enough for the proxy to work.
Since the cluster is still failing to retrieve the QFE information, I would suspect any of these could be the issue:

Try disabling any firewalls (also physical appliances)

Try disabling any antivirus software

Hello Leon,

If accurate, just try the host etc as an option.

However, the proxy is configured in the internet explorer options, but the problem remains.

The servers have the Firewall disabled, and they do not have antivirus.

At the group policy level, could the proxy configuration be forced?

The operating system firewall is disabled.

however on a physical level, you would have to talk with the client, who makes internal checks on their firewall to validate if there is any blockage with the proxy on these servers.

Warnings occurs to let you know that the process flow is not perfect but same time it is not a potential barrier for Validating Failover Cluster.

You can also use Windows PowerShell cmdlet, to run a set of focused validation tests. You can run this process on a collection of servers that you intend to use as nodes in a cluster.
