AMD RAID + Pre-existing LVM/Ubuntu installation

[VariableDeclared]

Hi,

I realise this is not a recommended setup but realistically if im to maintain a worklife/balance I want this configuration :)

I a pre-existing Ubuntu installation using LVM and I have the DKMS package installed, but when I configure GRUB with modprobe.blacklist=ahci my machine fallsback to Busybox.

I see that the kernel is compaining that it cannot find the disk by UUID. Any suggestions how to resolve this?

Thanks!

I also have this problem. I have an LVM install that I have DD'ed onto an rcraid array. mounting everything, chrooting in installing the driver, and generating the FSTAB works just fine. It wont boot.

It complains that it cant find /EFI/whatever fonts, and then tries to locate the disk by UUID and then fails.

It appears that the device is changing UUIDs, breaking the boot chain.

Upon further investigation the issue appears to be rcraid + encryption. After adding rcraid and regenerating the initramfs, it never bothers to ask for a decryption password. So it goes looking for UUID's of filesystems it cant read.

interesting @praxis88 did you find a way to solve it?

negative, I did a test run on a fresh install without encryption and it booted right up. Something about the driver and encryption arent getting along.

I could have done something wrong within the chroot, but I just chrooted in, installed the dkms module, built it against every kernel, generated a new initramfs for all of them, and updated grub. I never get a decryption password screen, just cant find UUID.
