Hi, I ran the command to restore etcd and nothing happened. Any idea why?
ETCDCTL_API=3 etcdctl --data-dir /var/lib/etcd-from-backup \
snapshot restore /opt/snapshot-pre-boot.db
I had taken the backup of the cluster with the command
$ etcdctl --cacert=/etc/kubernetes/pki/etcd/ca.crt --cert=/etc/kubernetes/pki/etcd/server.crt --key=/etc/kubernetes/pki/etcd/server.key snapshot save /opt/snapshot-pre-boot.db
