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

Products

• VMware Aria Suite

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 8.12.x and Later

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.

• Stop all the services by running the below command.

  service vmware-vcops stop

• Edit the roleState.properties file by running the below command.

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

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