How to restore etcd backup in stacked etcd HA cluster

Kubernetes
#1

I have 5 control plane stacked etcd cluster. I am trying to restoring the the etcd backup using below steps

mv /etc/kubernetes/manifests/etcd.yaml .
rm -rf /var/lib/etcd
ETCDCTL_API=3 etcdctl snapshot restore --data-dir /var/lib/etcd snapshot.db
mv etcd.yaml /etc/kubernetes/manifests/

Etcd restore is success but etcd cluster is not forming. It is acting as separate cluster.
Can someone please help me on this?

#2

It is expected to form a new cluster. Please follow carefully the steps for restoring a multinode cluster.
