Formatando o LVM
Qualquer sistema de arquivos pode ser usado para formatar o volume lógico; neste caso, o formato de sistema de arquivos utilizado é o ext4 (atualmente homologado).
| Aviso |

| Não é possível desfazer a formatação depois que concluída. Caso haja dados no volume, efetue o backup antes de formatar. |
