Replica Set Has No Primary

At time T, no primary was detected in replica set ABC.

  • The workload exceeds the cluster's throughput limits and compute resources.
  • A network issue with the cloud provider is preventing voting members of the replica set from communicating with each other, such that a primary cannot be elected.
  • Check the cluster's metrics to determine if there are sufficient compute resources for your workload.

    • If the cluster is exhausting CPU, disk IOPS, connections, or other resources, upgrade to a cluster that supports your workload.
    • If the cluster's metrics are normal, there could be a network issue with the cloud provider. Atlas automatically attempts to repair these issues. If the problem persists, contact MongoDB Support.
