Outlines how to add a node to an existing Qumulo cluster in GCP
Google Cloud Platform (GCP) account
- Google Deployment Manager API enabled
- GCP account limits large enough for the instances and volumes desired
- An SSH key-pair for accessing Qumulo instances via SSH
- Google Virtual Private Cloud (VPC) with at least one subnet configured in the target region
- Instances on the subnet must be able to access the internet (for example, via a NAT gateway)to support Qumulo's Cloud-based Monitoring
IMPORTANT! If you have configured IP failover for your cloud cluster, you must add additional floating IP's prior to adding another node. Additionally, the new node must have the same IAM role as existing nodes. Reference the Qumulo in GCP: Configure IP Failover article for additional details.
There are two methods of adding nodes to a Qumulo cluster in GCP, depending on how the cluster was originally deployed. The first mechanism is specific to clusters deployed via the GCP Marketplace, and the second uses Deployment Manager Templates and is meant to be used with deployments that were configured directly through Qumulo. If Qumulo originally deployed your cluster, you will need to contact firstname.lastname@example.org for additional assistance to successfully add additional nodes.
Contact your system administrator to confirm which type of deployment you have prior to adding capacity your cluster via the steps below.
GCP Marketplace Deployments
- Find the marketplace solution corresponding to your existing GCP Qumulo cluster’s SKU.
- Deploy that same solution:
- Set the instance count to however many nodes you want to add
- There may be fewer than 4, unlike when auto-clustering
- Don’t check the “automatically cluster you instances” checkbox
- Fill out the remaining fields as you did when first deployed your cluster, but use a new deployment name. Make sure you choose the same subnet as the existing cluster’s deployment so the nodes can talk to each other.
IMPORTANT! Keep in mind that if this new node uses an older version of Qumulo Core than your cluster, it must be upgraded before you can add it using the steps provided in the Qumulo in GCP: Upgrade an Unconfigured Node article.
Add Nodes to the Cluster via the UI
- Login to the Qumulo Core Web UI of your existing GCP cluster.
- Hover over the Cluster menu and click Add Nodes.
- Enter the list of IP addresses into the text box and click Add Selected Nodes to Cluster.
- Select Yes to confirm the addition of the selected node(s).
- A dialog box will display as the node(s) are configured and added to the cluster.
Once the new node is configured and added, the cluster Overview page will appear with a successful confirmation banner at the top. The newly-configured node(s) will now display in the listing table for the cluster.
NOTE: Existing nodes will retain their numbering once the new node is added.
You should now be able to successfully add a node to an existing Qumulo cluster in GCP
