Adding multiple nodes to an existing cluster in parallel hangs at "Waiting to finish cluster expansion. Starting the cluster for initial installation" in vRealize Operations Manager

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

Symptoms:

• Two or more nodes are added to an existing Aria Operations Manager cluster in parallel.
• The status of the cluster does not change from:
  

  Waiting to finish cluster expansion. Starting the cluster for initial installation

• Rebooting the nodes or restarting the services has no effect.

Environment

VMware Aria Operations 8.18.x

Cause

Adding multiple nodes to an existing Aria Operations Manager cluster in parallel is not supported. Cluster expansion must be completed one node at a time.

Resolution

Remove the newly added node by executing the following command as the root user on any node in the cluster.

curl -ik -u 'admin:password' -X DELETE https://primary_node_IP/casa/deployment/slice/node_to_remove_IP

Where:

• password is the admin user password
• primary_node_IP is the IP of the Primary node
• node_to_remove_IP is the IP of the node that you want to remove from the cluster
