 Posted: Fri Aug 02, 2019 6:26 pm Post subject: [SOLVED] Grub2 only gives: error: disk 'hd0,gpt1' not found |
 |
|
Hello all,
I have been trying to install Gentoo to my new Intel NUC8i7HVK. I'm aiming it to be installed so that the whole M.2 (NVME) disk is encrypted, and I'd use an un-encrypted USB stick as /boot, so its sort of a key to boot the machine. I just seem to be having a issue in that grub2 does not find any disks, even though grub2 itself does load. Something is hiding all the disks? Maybe EFI has some part in this, since this is the first machine I've had to utilize it?
Picture of the result:
https://pasteboard.co/IqNWN2L.jpg
Picture of trying to "ls" after setting debug=all:
https://pasteboard.co/IqNYyoP.jpg
I do not know why it complains about this hd0,gpt1 anyway, because the grub config does not seem to be even asking for it anywhere?
Here is the grub.cfg:
https://pastebin.com/MMfLdyyc
There might be some unnecessary "insmod"s etc from trying out different stuff to have some kind of effect on this issue, none of which have seemed to make any difference. When grub boots, if I press "e" on the boot menu entry, it shows that config as it is above, so it can read it ok.
blkid output:
https://pastebin.com/DBWAKzfq
Could it be that when I'm chrooted to the system using a archbang live usb, the grub-mkconfig names the devices differently, than when I remove the archbang live usb, and just try to boot from the intended /boot usb? There is no grub device map to give clues anymore as far as I know.(?) Maybe using USB stick as /boot is not as simple as I thought.
I have not been able to find any answers to this issue even though some people seem to have had almost the same issue, but they've just installed syslinux etc. to circumvent this problem. At the moment this computer is not essential to me, so I may keep it like this to find what the issue is, and maybe learn something along the way, which is mainly why I started on this journey with Gentoo anyway. I did install this following the handbook closely, and have made other Gentoo installs succesfully in the past, but those have not had encryption, lvm, uefi, or usb boot disk. Maybe I bit a piece too big for me to swallow...
Somewhat similar reports people have had in the past:
https://bbs.archlinux.org/viewtopic.php?id=238390
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1316068
I'd be very grateful for any directions and suggestions.

Tried to reinstall grub. Formatted the USB stick that has /boot (/dev/sdb1) and /boot/efi (/dev/sdb2) partitions. Swapped the partitions around so that fat32 esp partition /boot/efi is on first partition (/dev/sdb1) and ext4 /boot is on second (/dev/sdb2). Reinstalled kernel and initramfs, and ran "grub-install --target=x86_64-efi --efi-directory=/boot/efi" again. Grub.cfg looks pretty similar, and now the error is "error: disk 'hd0,gpt2' not found." So it did react to the partitions being in the other order, but still searches for hd0, instead of hd1 mentioned in the grub.cfg. All of the available commands either seem to do nothing, absolutely no output, or give the error disk not found message. Even "halt" gives disk not found.
efibootmgr -v seems to show the entry created correctly by grub-install.
No replies yet... Maybe my question is either too obvious, has insufficient information, or too difficult. Knowing which it is would also help. ^^ |

May be you need to create your initramfs with this
| Code: |
genkernel --luks --lvm --install initramfs
|
Furthermore if your /boot is on a usb does the fstab reflect this?
Can you post your fstab and /etc/default/grub plz?
Better use UUIDs in fstab for your mounts.
Do you have the "dolvm" and the luks flags in the GRUB_CMDLINE_LINUX="" in your /etc/default/grub?
You seem to have your /boot in one disk your efi in another and your / in another..
Is such complexity absolutely essential? |

Thanks alamahant,
Yes initramfs was created with:
| Code: | | genkernel --luks --lvm --keymap --firmware --install initramfs |
I did now do this again, after making sure /dev/sdb1 was mounted at /boot/efi and /dev/sdb2 mounted at /boot.
Current fstab that I updated after the previous partition adjustment:
| Code: |
# <fs> <mountpoint> <type> <opts> <dump/pass>
#swap
UUID=f88f766f-c7b8-4d69-aa0b-fbda45d101ac none swap sw 0 0
#root

#boot

/etc/default/grub has lots of comments, but here are the uncommented lines:

Is that "--hint-efi=hd1,gpt2" line wrong? /boot/efi is on partition /dev/sdb1, not /dev/sdb2. Should I correct this somehow? I did try to press 'e' again at grub menu and change this to "hd1,gpt1" and pressed F10, and got the same result, disk "hd0,gpt2" not found.
Here is the efibootmgr I did not add to my previous post:

Tried booting again, these above actions had no noticeable effect.
EDIT: forgot to answer this:
| Quote: | You seem to have your /boot in one disk your efi in another and your / in another..
Is such complexity absolutely essential? |
Aim is to have the whole M.2 SSD encrypted, and use the USB stick containing /boot and /boot/efi as sort of a key to boot the machine. I thought this was the easier approach, but maybe I was wrong. I do not however think this isn't a possible setup. I guess /boot and /boot/efi could be on the same fat formatted partition too, but some guides suggested to make it this way, so I did (, although those discussed migrating from bios to efi). |

Have you installed lvm2 and dosfstools ?
Try to do efibootmgr -n 0001 && reboot |

Parted says the following about the usb stick that is supposed to boot:
| Code: |
Model: Kingston DataTraveler 2.0 (scsi)
Disk /dev/sdb: 7807MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 211MB 210MB fat32 efi boot, esp
2 211MB 840MB 629MB ext4 boot
3 4138MB 7807MB 3669MB ntfs storage1 msftdata
|
Tried rebooting after efibootmgr command, no effect, the exact same result. "Gentoo" option is visible in UEFI menu, and grub does load the menuentries, and corresponding configs, but then gives error about hd0. Feels like grub is thinking it resides on hd0,gpt2, even though it is on hd1, gpt 1 or 2? I'm not sure if it installs on the /boot/efi partition or the other, mounted on /boot.(?) |

The last alternative probably  GRUB has documentation, but I find it rather lacking in some aspects. If GRUB is loading and presenting the menu, then the UEFI firmware at least knows how to handle booting from the USB stick and handing control to GRUB. So I wouldn't mess any more with efibootmgr. Instead, assuming you are able to make changes to grub.cfg and try booting afterwards, I'd comment out some of the insmod commands and commands that depend on that. I'll post a suggestion later. In the meantime, can we see your whole /etc/default/grub?

I do not have any other ESPs.
My hard drive, M.2 SSD, /dev/nvme0n1, is completely encrypted.
Parted:
| Code: |
Error: /dev/nvme0n1: unrecognised disk label
Model: Unknown (unknown)
Disk /dev/nvme0n1: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags:
|
It has only one physical volume in it, containing one volumegroup, with three logical volumes, one of which is the root, as you've seen above in blkid.
Removing the encryption, recreating the physical volume to allow for another partitions for /boot and /boot/efi, and reinstalling grub on the /dev/nvme0n1 sounds like a massive amount of work, and would probably mean I would have to do all of the work so far again, only to then start the work yet again to work towards the setup I wanted, which I have described, if it worked. I'm not very willing to do this yet.
Also I do think grub should at least see some disks, like the one it itself is installed on, when "ls -l" is input from the command line, or at least halt when given the command, instead of giving error about some unknown disk to almost every command.
I might try to install grub on some other usb stick though.
But I'll try the grub install with recheck first. |

All right. Let's try this. Comment GRUB_ENABLE_CRYPTODISK and GRUB_TERMINAL_INPUT, and change GRUB_PRELOAD_MODULES to just:
| Code: | | GRUB_PRELOAD_MODULES="part_gpt" |
I'm not sure if part_gpt is even needed, but I don't think it hurts leaving it there either. I suppose you handle LVM and LUKS in the initramfs (initramfs-genkernel-x86_64-4.19.52-gentoo, right?), i.e. after GRUB has handed control to the kernel, so I don't think lvm, cryptodisk and luks are needed. And leaving the USB stuff out is what I'd want to know the effect of.
Regenerate grub.cfg and try to boot again. If you are still able to get to the menu, press 'c' to get to GRUB's console, and tell us what does the ls command do now. |

You are correct, initramfs-genkernel-x86_64-4.19.52-gentoo was created with:
| Code: | | genkernel --luks --lvm --keymap --firmware --install initramfs |
Here is the /etc/default/grub lines that are uncommented now:
| Code: |
GRUB_PRELOAD_MODULES="part_gpt"
GRUB_DISTRIBUTOR="Gentoo"
GRUB_CMDLINE_LINUX="dolvm crypt_root=UUID="cba3f1f5-a4fa-4199-8377-e16d229fa1c9" root=UUID="f89b4582-0063-4f60-9952-58e9bb484850""
GRUB_DEFAULT=0

rerunning grub-mkconfig:
| Code: |
# grub-mkconfig -o /boot/grub/grub.cfg

Tried booting it... success(!), but maybe it was a fluke, so I retry... and SUCCESS again!!! Who knew insmod'ing absolutely every module under the sun would cause issues instead of repairing them. 
Some other issues still, but that's expected with Gentoo. Endless source of joy & problems, like having a second spouse.
Thanks a ton GDH-gentoo and alamahant ! Made a small donation to Gentoo foundation in celebration of this first solved issue of mine thanks to you. I'll see if I find out how to mark this solved. |

I know its and old thread but the only I found somehow relevant to my use case.
I am upgrading bit my 2 workstations both having same config:
supermicro x10sra-f
18 core intel xeon v4
and I wanted to have fast NVME drive.
First I had to throw away few years old Dell Quadro NMVE PCIE card which I was using just for data, neither older ASUS boards and these more recent Supermicro boards were not able to recognize more than 1 device even in bifubrication 4x4x4x4, I bought new adapter for 4x nvme by Asus and it workd, the Dell card is in trash as of today
Next I found some articles about requiring me to enable UEFI in bios at least in dual mode (both legacy and uefi in place), I moved /root and /boot partitions from old SSD drive, enabled UEFI install, but no luck: Replace boot media error
One thing was strange, that even the Bios shows NVME as drive, its not prefixed with UEFI: string,
I tried to boot it, and Grub was found by bios, but it was failing as i386 subfolder in /boot/grub was missing.
IMPORTANT
still in this state I was able to run ls and ls(hd0,gpt1) like commands just fine.
so even against recommendations found on internet I reinstalled grub with target=i386-pc and also created again 5mb partition with flag=bios_grub before that. Now Gentoo grub2 has following preloaded modules:
usb usb_keyboard ehci ohci uhci
but it loaded grub in state where it was just reporting on any command executed (i think this is grub bug):
hd0,gpt1 not found error
as per this thread I removed all those modules and put there only pure part_gpt which did the trick and I have my first workstation on nvme root. Now just dd to next drive and enable second machine. so thx a lot for this thread.
