I am seeing an issue where my cluster name will have 2 A records in DNS, one for the active node and one for the other node. There are no failover events in event viewer. This looks to be happening daily. Has anyone else seen this?

    Hi,

    Would you please provide a screenshot of the Cluster name, like below: (Please remove your privacy information. such as IP address)

    And provide the cluster DNS record in DNS server, like below: (Please remove your privacy information. such as IP address)

    Generally, the Cluster name A record is the cluster name with the IP address in my first screenshot.

    If your cluster A record is not that, please try to delete the wrong A record and try to offline the Cluster name and bring online the CNO again, the Cluster name A record will be re-register in the DNS server.

    Thanks for your time!
    Best Regards,
    Anne
