ETAPA 5 : Formatar o LVM
Qualquer sistema de arquivos pode ser usado para formatar o volume lógico, no nosso caso o método utilizado de sistema de arquivos é o ext4 que até o momento está homologado.
É importante tomar cuidado com esse comando pois não é possível desfazer a formatação depois que concluída, caso tenha dados favor efetuar backup.
