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
NOTE: Modifying the type or size of the volumes in the Google Marketplace listing will render the software not functional. Please use the default volume configuration available.
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.
Contact your administrator about which type of deployment you have first before proceeding to add capacity your cluster.
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.
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
