Outlines how to configure custom DNS servers and search domains in Qumulo Core
- Cluster running Qumulo Core 2.13.0 or later
NOTE: DNS entries will be automatically created from the node used to add the cluster to Active Directory and can be removed without issue during configuration.
In Qumulo Core 2.13.0 and above, you can configure custom DNS server and search domains even when your cluster is not using a static IP configuration. Once these settings are configured, the set value will replace the one originally configured by DHCP on your cluster.
NOTE FOR GCP CLUSTERS: If you wish to use a custom DNS configuration with a cluster deployed in GCP, we recommend using the Google Internal DNS server (169.254.169.254) to forward requests to your own custom DNS for all GCE instances. If your custom DNS is required to be the DNS server for your GCE instances, ensure forwarding is configured to Google’s internal DNS for compatibility with many cloud features. For more information, check out the Best Practices for DNS Forwarding Zones and Internal DNS details in the GCP documentation.
Follow the steps below to configure, verify, or clear custom DNS servers and search domains.
Set a Custom DNS Configuration
To setup a custom DNS configuration on your network, specify the interface, network IDs, and desired DNS information using the following command:
qq network_mod_network --interface-id ID --network-id ID --dns-servers IP1 IP2 --dns-search-domains "DOMAIN1" "DOMAIN2"
NOTE: As shown above, multiple entries can be separated by spaces.
Verify a Custom DNS Configuration
Use the following command to verify your custom DNS configuration:
qq network_get_network --network-id ID
See the following example output:
test:~$ qq network_get_network --network-id 1
Clear a Custom DNS Configuration
Use the following command to clear your custom DNS configuration:
qq network_mod_network --interface-id ID --network-id ID --clear-dns-servers --clear-dns-search-domains
Once you clear the custom configuration using the command above, the settings will revert to those assigned by DHCP on your cluster.
You should now be able to successfully configure custom DNS server and search domains with Qumulo Core
