Я создал собственный AMI и зарегистрировал его на Amazon EC2. Но при запуске AMI я получаю следующую ошибку:
Паника ядра - не синхронизируется: VFS: невозможно смонтировать root fs на unknown-block (8,1)
Образ работает локально без проблем.
fstab содержит:
proc /proc proc defaults 0 0
/dev/sda1 / ext3 relatime,errors=remount-ro 0 1
Изображение было создано с помощью следующей команды
ec2-bundle-image -i image.raw -r i386 -c cert-xxx.pem -k pk-xxx.pem --user 123456
