Formatando o LVM
Qualquer sistema de arquivos pode ser usado para formatar o volume lógico; neste caso, no nosso caso o método utilizado formato de sistema de arquivos utilizado é o ext4 que até o momento está homologado.É importante tomar cuidado com esse comando pois não (atualmente homologado).
| Aviso |
|---|
|
| Não é possível desfazer a formatação depois que concluída. Caso haja dados no volume, efetue o backup antes de formatar. |
, caso tenha dados favor efetuar backup.

Configuração para mapear e utilizar o volume no boot
Esta configuração é importante para que não seja necessário mapear e montar o novo volume, todas as vezes que a máquina for reiniciada. ETAPA 7 : Iniciando automaticamente o volume criado para o uso dos dados na máquina primária.
