Qumulo in AWS: Launch a New Node for an Existing Cloud Cluster

IN THIS ARTICLE

Outlines how to launch a new node for your existing Qumulo cloud cluster in AWS

REQUIREMENTS

• A Qumulo cluster in AWS running Qumulo Core 2.12.4 or above
• AWS Console access with permissions to launch instances
• AWS account limits large enough to deploy the desired instances and volumes

IAM PERMISSIONS

The ec2:RunInstances IAM permission is required to launch a new node for an existing Qumulo cloud cluster in AWS. 

DETAILS

One of the perks of hosting your storage in the cloud is the ability to dynamically add more capacity as your storage needs increase. Starting up a new node (a.k.a, launching a new instance) is a simple process while adding the instance to an existing cloud cluster is even easier.

Launch a New Node

1. Click Instances in the left-hand navigation pane on your EC2 Dashboard.
   
   
   
   
2. Select one of your Qumulo instances as shown in the image above.
3. Click Actions and select Launch More Like This.
   
   
   
   
4. Click the 4. Add Storage tab.
   
   
   
   
5. Use the Encryption column to specify the encryption key to be used. If no specific key is required, set the value to (default) aws/ebs.
   
   
   
   
6. Return to the 7. Review tab and verify that the instance uses the exact same VPC, Subnet, Security Group, Instance Type, SSH key, and tags as the instance it was created from. If any of these settings need to be changed, do so before launching.
7. Launch the instance and note its IP address and Instance ID. The IP address will be used when adding these nodes to an existing cluster.

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 your cluster using the steps provided in the Qumulo in AWS: Upgrade an Unconfigured Node article. Once the software version matches between the cluster and the new node, you can add it to your cluster using the Qumulo in AWS: Add a Node to an Existing Cloud Cluster article as a guide.

RESOLUTION

You should now be able to successfully launch a new node for an existing Qumulo cloud cluster in AWS
