2.2. Identifying an unhealthy etcd member

You can identify if your cluster has an unhealthy etcd member.

Prerequisites

  • Access to the cluster as a user with the cluster-admin role.

Procedure

  1. Check the status of the EtcdMembersAvailable status condition using the following command: 

    $ oc get etcd -o=jsonpath='{range .items[0].status.conditions[?(@.type=="EtcdMembersAvailable")]}{.message}{"\n"}'

  2. Review the output: 

    2 of 3 members are available, ip-10-0-131-183.ec2.internal is unhealthy

    This example output shows that the ip-10-0-131-183.ec2.internal etcd member is unhealthy.
