Known Affected Releases
Symptom: Adding a node to a Cisco DNA Center multi-node cluster may fail when (during the install process) etcd won't start on the node being added to the cluster. Conditions: The issue is caused on the node being added to the cluster when a value in the parameter is missing in the etcd.manifest file for the initial-cluster configuration. To assess the condition, login to the node and run the following commands. # Check that the kube-apiserver is running; only proceed to the next step if the kube-apiserver status shows as Exited docker ps -a | grep kube-apiserver # Check the kube-apiserver's docker log to check if is reporting an issue with connecting to etcd docker log <kube-apiserver's-docker-id> # Run netstat to check if etcd is listening on ports 2379 and 2380 netstat -tnl # Check if etcd is running docker ps -a | grep kube-apiserver # Check etcd's log for the string "couldn't find local user 'etcd-<IP-address>' in the initial cluster configuration docker log <etcd's-docker-id> If the above conditions are met, then this issue is being encountered. Please open a TAC service request for assistance.
