Hello everyone again.

I am new in sabayon community and i just install the new Sabayon 7 amdx64 Gnome on an external hdd conected via usb on a vaio vgn sz 650 n. The installation progress completed without any errors. Anaconda ask for reboot and i press the button. On booting procedure i had the following error:

"Block device /dev/mapper/vg_sabayon-lv_root is not a valid root device.
Could not find the root block device in.
Please specify another value or press: Enter for the same, type "shell" for a shell, or "q" to skip root block device."

I follow all three steps (press ENTER, press Q, type shell) but i don't know how to fix the problem. I think the solution is on changing something in grub.cfg
Please help.....

GRUB configuration is:
setparams 'Sabayon GNU?LINUX, with Linux x86_64-3.0.0-Sabayon'

load_video
insmod=part_msdos
insmod=ext2
set_root='(hdd1,msdos1)'
search --no-flopy --fs-uuid --set=root 650260e4-2b3f-4ed4-be93-637579b91ede
echo 'Loading Linux x86_64-3.0.0-sabayon...'
linux /kernel-genkernel-x86_64-3.0.0-sabayon ro init=/Linux rc splash=silent,theme:sabayon vga=791 console=tty1 quiet dokeymap keymap=us domdadm resume=swap:/dev/mapper/vg_sabayon-lv_swap real_resume=/dev/mapper/vg_sabayon-lv_swap dolvm root=/dev/mapper/vg_sabayon-lv_root docrypt

On which partition did you install Sabayon. You use lvm?

[pit_haris]

I made a clean installation on an external usb drive i thing it was seen by the program as sdc.
Sorry for the delayed response. Thanks for your concern.

[raman]

What program did you use to install on USB?

[raman]

Anyway I think that you can edit grub and changing:

Code: Select all

root=/dev/mapper/vg_sabayon-lv_root

for

Code: Select all

root=/dev/sdc1

or whathever partition did you install

Thanks a lo t. I will try with and i will inform you about. The point is that this error is shown in the middle of boot procedure. Anyway thanks a lot again.

Anaconda (the sabayon installer) put the grub. I didn't do anything, I try another installation and i choose the "use all space" option for the partitioning. Anaconda said the follows:

LVM Volume Groups
vg_sabayon 113952
lv_root 51200 / ext4
lv_swap 6016 swap
lv_home 56736 /home ext4

Hard Drives
sdb
sdb1 500 / boot ext4
sdb2 113952 vg_sabayon physical volume (LVM).

Please a small help again if it possible.....

I thing that the reason of the error on grub is because lvm is not starting during the boot procedure. How can i start lvm during boot loading???
