Hello everybody,

New to Gentoo I'm trying to install this OS on a HP Proliant ML350p Gen8.

I'm also trying to speak english...

I tried four or five time to install, reset the server to factory defaults, wipe the disks but still no success...

I have made a lot of searches on the Internet and in this forum but I didn't find anything that could help me to solve this.

Maybe the solution was in the pages I read but I didn't understand that it could apply to my problem...

The post is long but I choose to give all informations I gathered during installation, this could be also useful for other people...

The installation seems to be ok but after reboot I get this error message : !! Could not find the block root device in UUID=08486b40-6e58-4174-9c29-47bb5643ebc2

I followed this handbook : https://wiki.gentoo.org/wiki/Handbook:AMD64

The hardware :

HP Proliant ML350p Gen8
HP Bios P72 08/02/2014 (this is a legacy boot, there is no UEFI available)
There is a Hard RAID : HP Smart Array P420i Controller
There are 2 x 3TB SATA drive - RAID 1 (one logical volume of 2,7 TB)
32 MiB RAM (will add 32 MiB RAM more soon)

You'll find more details below.

Here is the whole process :

Local server
boot from livecd boot-repair-disk
Launch gparted and remove all partitions
Create a msdos partition table
quit gparted and shutdown

Then I boot from install-amd64-minimal-20150702.iso CD
Code:
loadkeys fr
/etc/init.d/sshd start
passwd
ifconfig eno1 --> inet 192.168.1.66


Laptop
I'm connecting from my laptop to the server
Code:

This is a little bit strange because the disk should not contain a previous ext2 file system.

Anyway I still follow the handbook...

Then the boot process begin but stops here

I didn't read all the details, but AFAIR I had a hard time with such a system a couple of years ago trying to boot on RAID1 with BOOT NG system disk to manage partitioning, which I've been using for ages now!!!
Installing Win2003 was a breeze though.
I suspect there is a strong bios routing there...

Good luck

Thks 4 ur attention.

I've been in the same situation with installs in the past on a dedicated server in a data center, sometimes Grub doesn't effectively set the root= when it finishes installing and thus when you reboot it doesn't work.

I would suggest getting to a grub recovery console and trying out the steps highlighted at https://www.linux.com/learn/tutorials/776643-how-to-rescue-a-non-booting-grub-2-on-linux/ and seeing if you can get it to boot from there. If you get it to boot using that then I would suggest running grub2-mkconfig -o /boot/grub/grub.cfg again but inside of the now booted system then when you reboot everything should work as expected.

Welcome to Gentoo.

After fat fingering this post three times, I'll just say that you need the hpsa kernel driver. The kernel help says
Code:
  | Symbol: SCSI_HPSA [=n]                                                  | 
  | Type  : tristate                                                        | 
  | Prompt: HP Smart Array SCSI driver                                      | 
  |   Location:                                                             | 
  |     -> Device Drivers                                                   | 
  |       -> SCSI device support                                            | 
  | (1)     -> SCSI low-level drivers (SCSI_LOWLEVEL [=n])                  | 
  |   Defined at drivers/scsi/Kconfig:369                                   | 
  |   Depends on: SCSI_LOWLEVEL [=n] && PCI [=y] && SCSI [=y]               | 
  |   Selects: CHECK_SIGNATURE [=y]


Also, you don't get a 2.7TB partiton from two 2TB drives in raid1.

Thanks for your quick answers, really appreciate that.

That's what I thought too first. But after a few hours digging in the HP BIOS I'm quiet sure the BIOS is not guilty (see below)

I followed your advice and learned a lot about grub recovery console, maybe there is a clue now.

Have a look at what I did :

At boot screen I press the "c" key

Code:
GNU GRUB version 2.02~beta2
grub> set pager=1


Let's have a look to partitonning
Code:
grub> ls
(hd0)  (hd0,gpt4)  (hd0,gpt3)  (hd0,gpt2)  (hd0,gpt1)


Just for information purpose
Code:
grub> ls (hd0,1)/
error : unknown filesystem

(error message translated from french)

Just for information purpose
Code:
grub> ls (hd0,3)/
error : unknown filesystem

(error message translated from french)

List the content of /dev/sda2
Code:
grub> ls (hd0,2)/
lost+found/ kernel-genkernel-x86_64-4.0.5-gentoo System.map-kernel-genkernel-x86_64-4.0.5-gentoo initramfs-genkernel-x86_64-4.0.5-gentoo grub/


List the content of /dev/sda2/grub
Code:
grub> ls (hd0,2)/grub/
i386-pc/  locale/  themes/ fonts/ grubenv grub.cfg


List the content of /dev/sda4
Code:
grub> ls (hd0,4)/
lost+found/ boot/ stage3-amd64-20150709.tar.bz2 sys/ bin/ usr/ media/ root/ dev/ proc/ tmp/ run/ lib var/ lib32/ etc/ mnt/ home/ lib64/ opt/ sbin/


List the content of /dev/sda4/boot
Code:
grub> ls (hd0,4)/boot/

grub>

This is empty as you can see

Just to be sure exit grub and reboot the server from install-amd64-minimal-20150702.iso CD

Code:
livecd ~ # mount /dev/sda4 /mnt/gentoo
livecd ~ # ls /mnt/gentoo/boot
livecd ~ #

This folder is empty as grub said

Code:
livecd ~ # mount /dev/sda2 /mnt/gentoo/boot
livecd ~ # ls /mnt/gentoo/boot

Again, Grub was right

Now let's go back to grub, have a beer because it's friday, and according to https://www.linux.com/learn/tutorials/776643-how-to-rescue-a-non-booting-grub-2-on-linux/ let's try a couple of things.

Code:
grub> set root=(hd0,4)
grub> linux /boot/kernel-genkernel-x86_64-4.0.5-gentoo root=/dev/sda4

Obviously this is useless because there is nothing in /dev/sda4/boot/ as previously seen. Grub and the completion, which are smarter than me, tell me there is no available file here...
So I won't go further

Let's try another thing
Code:
grub> set root=(hd0,2)
grub> linux /kernel-genkernel-x86_64-4.0.5-gentoo root=/dev/sda2
grub> initrd /initramfs-genkernel-x86_64-4.0.5-gentoo
grub> boot


Then the boot process begin but stops here
Code:
>> Determining root device...
!! Block device /dev/sda2 is not a valid root device


Ok, now just a last dummy attempt

let's go back to grub and change argument for root=

Code:
grub> set root=(hd0,2)
grub> linux /kernel-genkernel-x86_64-4.0.5-gentoo root=/dev/sda4
grub> initrd /initramfs-genkernel-x86_64-4.0.5-gentoo
grub> boot


Then the boot process begin but stops here
Code:
>> Determining root device...
!! Block device /dev/sda4 is not a valid root device


Conclusion :

As far as I understand the boot process is looking for /dev/sda4/boot/kernel-genkernel-x86_64-4.0.5-gentoo and /dev/sda4/boot/initramfs-genkernel-x86_64-4.0.5-gentoo

Unfortunatly these files are located in /dev/sda2.
And these files are not yet mounted in /dev/sda4/boot/ (according to the fstab) when the boot process begin

I'll just say that you need the hpsa kernel driver

How do I achieve this using genkernel (if possible) ?

Another thing I don't understand :

You remember I have 4 partitions

Code:
(parted) print                                                           
Model: HP LOGICAL VOLUME (scsi)
Disk /dev/sda: 2861556MiB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start      End         Size        File system  Name    Flags
 1      1.00MiB    3.00MiB     2.00MiB                  grub    bios_grub
 2      3.00MiB    131MiB      128MiB                   boot
 3      131MiB     131203MiB   131072MiB                swap
 4      131203MiB  2861555MiB  2730352MiB               rootfs


But there is only 3 partitions in the /etc/fstab file

Code:
/dev/sda2               /boot           ext2            defaults,noatime        0 2
/dev/sda3               none            swap            sw              0 0
/dev/sda4               /               ext4            noatime         0 1


Did I miss something in the /etc/fstab file ?

Thanks for your help

LaFigue,

First, a little about the boot process and the term root used in two different contexts to mean two different thngs.
The process is similar for both BIOS and EUFI so I will gloss over the detailed differences.

At power up, there is only empty RAM and the PC firmware. The firmware des its thing setting up the hardware, some testing, then loads your boot loader. Loading the boot loader is not simple, its in several pieces. Like a cascade of loaders, each one more capable than the last. In grub-legacy, its in three stages.

The boot loader shows you the menu. You make your choice ang the boot loader loads your kernel and optionally, your inirrd.
It then jumps to the kernel start address. The boot loader cannot use the kernels filesystem tree, nor can it use the kernel to read any files. The kernel isn't running. Indeed its in RAM but still compressed. Bootloaders must make their own arrangements to read your hard drives. Keep that in mind as you read the next fragment.

Code:
grub> set root=(hd0,4)
grub> linux /boot/kernel-genkernel-x86_64-4.0.5-gentoo root=/dev/sda4


The set root=(hd0,4) is telling grub where to find the files it will load. The (hd0,4) is grubspeak for the fourth partition on the first discovered HDD. It might be /dev/sda to the kernel later but that does not yet exist. We are still loading a kernel.
linux /boot/kernel-genkernel-x86_64-4.0.5-gentoo tells the file to load that can be executed. Normally a kernel.
root=/dev/sda4is passed to the kernel to tell it where the root filesystem is. The kernel cannot find out from /etc/fstab as the root filesystem is not yet mounted, so /etc/fstab cannot be read.

Notice the two different uses of root to mean different things.

Bootstrapping is all about breaking circular logic. Its named after the Greek mythological character who pulled himself up to heaven by tugging on his own bootstraps.

Code:
grub> ls (hd0,2)/
lost+found/ kernel-genkernel-x86_64-4.0.5-gentoo System.map-kernel-genkernel-x86_64-4.0.5-gentoo initramfs-genkernel-x86_64-4.0.5-gentoo grub/
This is clearly your boot partition. As it contains lost+found, we know that its the top level of a filesystem on a partition. It also contains kernels and initrd files. So you need
Code:
set root=(hd0,2)
to point grub here to load your kernel and initrd.

Code:
grub> ls (hd0,4)/
lost+found/ boot/ stage3-amd64-20150709.tar.bz2 sys/ bin/ usr/ media/ root/ dev/ proc/ tmp/ run/ lib var/ lib32/ etc/ mnt/ home/ lib64/ opt/ sbin/
This is a kernel root filesystem, so you have root=/dev/sda4The sda bit may not be correct but lets ignore that for now.

Your two partitions with no filesystems will be swap and a small grub partition. They are used directly by the kernel and grub.
swap should be listed in fstab but the grub partition shoud not.

This brings us on to the two different uses of boot and why (hd0,4)/boot is (correctly) empty.
You have a directory called /boot (leading /) on your root filesystem. You have a partition called boot (no /) which is (hd0,2)
The partition called boot is normally attached to the /boot directory, so the content of the boot partition appears at /boot.
When you look with grub the filesystem tree has not been assembed so you see all the bits on their own,

Genkernel has a -menuconfig option to allow you to make changes to the options before the build takes place.

Thanks a lot NeddySeagoon, the server is up now !

That's it ! I made this :
Code:
genkernel --menuconfig all

Then I have activated the HP Smart Array SCSI driver, save the config and exit the menuconfig utility.
Then the compile process has started and ended normally.

I have rebooted the server and everything was fine.

Thank you for your support.

Also, you don't get a 2.7TB partiton from two 2TB drives in raid1.

That's right there is 2 x 3 TB drives, I've edited my post to change that.
