Description Baptiste Wicht 2014-10-10 09:25:49 UTC
I installed Gentoo on a virtual machine (VMware player), with LVM,sytemd and Grub2. I performed this installation several times without any problem on other machines. 

When I boot, I got this message:

!! /dev/mapper/vgo-root is an invalid root device
!! Please file a bug report with this message

I tried genkernel-next-55 and genkernel-next-58 with the same effect. I checked genkernel-next code and it is generated because ${REAL_ROOT} is not a block device, although I don't know why. I tried configuring grub2 on /dev/dm-0, but the problem is the same. 

The initramfs was generated with: 

genkernel --lvm --udev --install initramfs

I don't see anything else when it boots, but perhaps I'm missing a message. 

I can provide more information, but I don't really know what is relevant to this bug. Just tell me what to include and I'd be glad to provide any information. 

Reproducible: Always

sys-kernel/genkernel-next-58 was built with the following:
USE="-cryptsetup -dmraid -gpg -iscsi -plymouth (-selinux)" ABI_X86="64"
Comment 3 Yixun Lan archtester gentoo-dev 2014-12-17 14:28:35 UTC
I kind of experience of same problem, haven't dug too much.

what's I noticed is a) build kernel with genkernel-next at lvm system, has no problem. b) build kernel with genkernel-next at non-lvm system,and transfer initramfs/kernel to a lvm machine, have problem to boot
Comment 4 Pacho Ramos gentoo-dev 2015-05-23 09:26:26 UTC
is this still valid for version 63?
