[gentoo-user] plain copy of root disk won't work

[Raffaele BELARDI]

I want to move the main disk contents (hda, PATA) to another, larger 

disk (sda, SATA).



hda contains 4 ext3 partitions (root, home, data, swap).

I created 4 ext3 partitions on sda and copied the data over from the 

corresponding hda partitions using 'cp -ax'.

Then I chroot into sda1, 'grub-install /dev/sda', grub-mkconfig and edit 

fstab to use sda instead of hda.

Reboot, from the non-UEFI bios change the disk boot order and try to 

boot from sda.

grub from the sda starts, loads the kernel from sda1, the kernel finds 

the root file system and mounts it RO but then the process stops at the 

end of the kernel boot. No kernel panic, just hangs there with the last 

kernel message before openrc. Openrc is not started.



What might I be missing?



thanks,
