Eu tenho um modelo CloudFormation funcional que cria volumes EBS de instância 2 da AWS. Os volumes são visíveis na máquina via lsblk. Só estou tendo problemas para formatá-los e montá-los. É como se o script UserData não estivesse em execução.
É uma máquina Ubuntu 14.04. Alguma ideia do que posso estar fazendo de errado?
EDIT: adicionado modelo completo para referência

Aqui está a resposta: o EBS precisa estar totalmente conectado.
