EDR: Cluster Fails Starting cb-datagrid Service

[#1]

Environment

• EDR Server: All Supported Versions

Symptoms

• One or more node's cb-datagrid service fails to startup in the cluster.

Cause

Datagrid cannot communicate without Postgres

Resolution

1. Verify the cb-pgsql service is running on the primary node

   • service cb-pgsql status

2. Confirm network communication between minion nodes and primary node, including port 5002, and 5701 are successful
3. Ensure the cb-datagrid service isn't stopping on one of the minions

Additional Notes

• During cluster startup, the primary node's cb-datagrid service will wait for all other minions to start first
• Datagrid relies on the primary node's cb-pgsql  to be up and accessible across the cluster
• All nodes pull information from the cb-pgsql service on the primary node to successfully start cb-datagrid
