Symptoms

Customer did not have the management interface in DNS on the passive head of an active/passive cluster. After the upgrade the system was left running on the passive head.

It was noted that the following messages were filling up logs/debug.sys

Unable to generate negotiation blob (GSS minor error): host/domain name not found

Oct 11 11:00:21 systemname smbd[2328]: [ID 165786 daemon.notice] Unable to generate negotiation blob (GSS major error): Unspecified GSS failure. Minor code may provide more information
Oct 11 11:00:21 systemname smbd[2328]: [ID 648024 daemon.notice] Unable to generate negotiation blob (GSS minor error): host/domain name not found.

While the customer didn't experience any performance issues with SMB, the log entries were reported quite frequently.

Cause

The management interface on the passive head did not have a DNS entry.

Solution

Add an alias for that management interface into DNS
