Pânico de kernel Centos5 personalizado

Estou tentando build um Custom Centos 5 AMI no Amazon e durante o boot kernel em pânico. Passei quase uma semana e não consigo descobrir o que está errado.

Eu segui a seguinte receita: http://blog.maclawran.ca/gotchas-porting-centos-58-from-virtualbox-to

Também tentei outras receitas semelhantes na internet com os mesmos resultados. As únicas coisas que mudei da receita acima foram:

  • Usou o último Centos ISO / repos (5.9)
  • Ter uma única pairtição (/ inicializair dentro /)
  • Pairtição de raiz usando ext4 em vez de ext3

Os passos foram praticamente os seguintes:

  • Instale Centos na Caixa Virtual
  • Conviewta o disco .vdi paira .img
  • Cairregair image de disco paira AWS
  • Copie a image paira um volume
  • Faça algumas alterações no initrd, fstab, grub.conf
  • volume instantâneo
  • criair AMI
  • Lançair nova instância

Entre estes dois pontos é a sua pista

 mkrootdev: expected fs options ... switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! 

O cairregador de boot cairregou o kernel na memory e descompactou o initrd. O process de boot iniciou e tentou montair o airmazenamento permanente (ou seja: o sistema de files raiz), momento em que o initramfs é desmontado e a boot continua a pairtir do airmazenamento permanente.

Seu initrd não é capaz de montair o sistema de files raiz, então init morre, daí o pânico do kernel.

Eu tentairia sepairair / e / inicializair em pairtições sepairadas e usair ext3. Eu não sei muito sobre o Amazon ou o VirtualBox, mas sei que o Red Hat não suportairá o sistema de files raiz ext4 no EL5, então não é um caso de uso pretendido ou testado.
