I'd like to expand my single node Aria Operations deployment to include a Data Node, here's how to do it!
Deploy an Aria Operations appliance via OVA, same size and same version as the Primary Node, and power it on. Once powered on, access the provided URL and follow the wizard.
Click EXPAND AN EXISTING INSTALLATION.
Give your Node a name, type (in my case Data), point it at the Operations Cluster Primary Node, VALIDATE, Accept this Certificate, and click NEXT.
Provide the Operations cluster admin credentials and click NEXT.
Click FINISH, which will take you to the admin UI indicating the new Data Node is being prepared.
Which will be updated over the next few minutes.
Click FINISH ADDING NEW NODE(S).
And our Data Node has been added. Which you can also see from the regular UI and Administration - Cluster Management.
To balance Objects and Metrics across both Nodes in the Cluster go to ACTIONS - Rebalance.
When prompted, select Rebalance Disk and OK.
And now we're rebalanced!
In our next blog we'll explore activating HA!
