INDETERMINATE Cluster failover status

Products

• VMware Cloud Director
• VMware Telco Cloud Infrastructure

Issue/Introduction

• After upgrading VMware Cloud director (VCD) the cluster failover status is marked as INDETERMINATE
• One/two Cloud Cell(s) node(s) exhibiting a failover status that does not match the other node(s).

Environment

VMware Cloud Director 10.x

Cause

INDETERMINATE status occurs when a Cloud Cell node is configured with a different failover status (manual or automatic).

Resolution

To align the failover status of the affected node with the rest of the cluster, use the following API calls:

1. Create a new session to get the authorization token:
   
   POST https://{api_host}/api/1.0.0/sessions
   
   For additional information visit Post Sessions
   
   
2. Check the postgres HA state of all nodes in the cluster using the following API and the token generated from step 1:
   
   GET https://{api_host}/api/1.0.0/nodes

For additional information visit Get Nodes
   
   
3. If the failover mode is not the same across the nodes in the cluster, proceed with the step 4 to change the failover status for the affected node.
4. Change the failover mode on the node:
   
   POST https://{FQDN or IP of the node}/api/1.0.0/nodes/failover/{desired-mode}

   or using the command: 

   curl -X POST -H "Accept: application/json" -H "Authorization: Basic [[basicHash]]" -H "Accept: application/json" "https://vcd-appliance-ip:5480/api/1.0.0/nodes/failover/{desired-mode}"

   Valid values are:

   automatic
manual

   For additional information visit Post Set Failover Mode
   
   
5. Verify the status change by re-checking the cluster status as per step 2

VMware Cloud Director Appliance API - Failovermode

You can also use the curl command instead of an API client:

1. 1. Obtain Bearer TOKEN
      

      curl -k -u root -X POST "https://<VCD-NODE-FQDN-OR-IP>:5480/api/1.0.0/sessions"

   2. Change Failover Mode Note: (This will update the failover mode for all cells)
      

      curl -k -i -X POST -H "Accept: application/json" -H "Authorization: Bearer <YOUR-AUTH-TOKEN>" "https://<VCD-NODE-FQDN-OR-IP>:5480/api/1.0.0/nodes/failover/{desired-mode}"

      Note: replace {desired-mode} with "automatic" or "manual"
