@ajainvivek Is it a newly built cluster? I realized that all other components (master, nodes) have been upgraded from etcd2->etcd3, but I did not for Vault. CoreOS now removed etcd2 service. It will cause vault server to fail. I just fixed the vault. Please pull the latest change and following the upgrade-vault. Then master and nodes. Hopefully it would recover.
