Não foi possível encontrar os volumes LVM: opções do kernel do Linux

Question

Após a recompilação do kernel, não consigo inicializar uma caixa linux.

Erro ao não encontrar os volumes LVM.

Você pode me indicar as opções de configuração do kernel necessárias para ativar a inicialização a partir do LVM2?

Tenho certeza de que esqueci algo importante.

Eu sabia que DM é necessário, mas ou eu não habilitei ou há algo mais.

Ative as seguintes opções do kernel:

KERNEL
Device Drivers  --->
   Multiple devices driver support (RAID and LVM)  --->
       <*> Device mapper support
           <*> Crypt target support
           <*> Snapshot target
           <*> Mirror target
       <*> Multipath target
           <*> I/O Path Selector based on the number of in-flight I/Os
           <*> I/O Path Selector based on the service time

• Nem tudo precisa ser ativado; algumas das opções são necessárias apenas para Instantâneos LVM2 e Instantâneos Finos LVM2, Espelhos LVM2, LVM2 RAID 0 / Stripeset e criptografia.
