Adding a Data node to Aria Operations fails to finish the cluster expansion task.

Products

• VCF Operations/Automation (formerly VMware Aria Suite)
• VCF Operations

Issue/Introduction

• Aria Operations fails to finish the add new data node task.
• In the Admin UI the new node will display the status OFFLINE - Not Running and the existing nodes will be in an ONLINE - Running status
• There is no option to cancel the task.

Environment

• Aria Operations 8.18.x
• VCF Operations 9.0.x

Cause

• The add new node task will fail to complete if the disks allocated to the new node are not the same total size as the existing nodes in the cluster.
• For environmental reasons the task will hang and never complete.

Resolution

To resolve this issue:

1. Take snapshots of all the nodes in the cluster.
2. Issue the following commands on the all the analytics nodes (Primary, Primary Replica and Data) via SSH as root.

   1. Stop all the services by running the below command:

      service vmware-vcops stop

   2. Edit the roleState.properties file by running the below command:

      vi /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/data/roleState.properties

   3. Locate the line that reads 'sliceonline = true' and change it to 'sliceonline = false'.
   4. Save and exit the file by running the command:

      :wq!

   5. On the Primary only run the following command:

      /etc/init.d/vmware-casa restart

3. Log in to the Admin UI - Cluster Status page and you should now have the option to 'Finish adding the new node'.
