[solved] [grub] `unknown filesystem` trying to boot from btrfs filesystem | Arch Linux Community | Page 1

carmine blade Sep 8, 2022, 7:50 PM

#

Solution: used /dev/sda instead of /dev/sdb (no explanation, don't use the advice)

Hey so. I just installed Debian, and here's what I did:

I merged two physical drives sda and sdb into one volume group with lvm
I created two logical volumes, one with btrfs and the other one with swap
Once the installer asked about grub, I chose sdb to install to
Now it falls into grub's rescue shell with error unknown filesystem
For some reason too few commands are available. There's no command boot, normal, lsblk and others which people suggest and use on stackoverflow with this error

Any idea?

#

The first pic is the default grub's options
in the second pic I booted from another OS from usb
in the third pic I mounted the drive to see what's up, it mounted and has all the needed files

#

Oh, I omitted important fact. Doing ls (hd0) (and for all three other things) fails with unknown filesystem too

#

I suspect that it's due to the fact that I installed it on sdb and the default prefix is (hd0,msdos1) which I guess means sda

Are you booted into the btrfs system when you do the grub-mkconfig?

carmine blade Sep 8, 2022, 8:51 PM

#

agile perch Are you booted into the btrfs system when you do the grub-mkconfig?

I do what?

#

Should I try that command?

#

or what, sorry

agile perch Sep 8, 2022, 9:08 PM

#

How do you make mkconfig? Is that the update-grub command?

carmine blade Sep 8, 2022, 9:08 PM

#

agile perch How do you make mkconfig? Is that the update-grub command?

I have no idea what you're talking about, sorry. I installed grub by clicking "yes" when the installer suggested to install it

#

I never successfully booted into the system yet

agile perch Sep 8, 2022, 9:09 PM

#

Grub needs a configuration file

#

Chroot into the root and run update-grub

#

I assume your root is the btrfs partition

carmine blade Sep 8, 2022, 9:10 PM

#

it is

agile perch Sep 8, 2022, 9:10 PM

#

I believe update-grub will run the configuration generation

carmine blade Sep 8, 2022, 9:10 PM

#

there's no chroot

agile perch Sep 8, 2022, 9:10 PM

#

Once that is done show us ls /boot and ls /boot/grub

carmine blade Sep 8, 2022, 9:10 PM

#

and there's no grub-update either

#

there's no even command cd

agile perch Sep 8, 2022, 9:11 PM

#

carmine blade there's no chroot

You can only chroot from iso

carmine blade Sep 8, 2022, 9:11 PM

#

ah one sec then

agile perch Sep 8, 2022, 9:11 PM

#

You’ll need to look up a guide on how to chroot into your Os, I only chrooted into arch before

carmine blade Sep 8, 2022, 9:13 PM

#

but why do you think the config file is the problem?

#

shouldn't it have been created on install?

agile perch Sep 8, 2022, 9:15 PM

#

I don’t know if it is an issue or the only issue, just that it might be an issue, on top of that I’d try reinstalling the kernel

carmine blade Sep 8, 2022, 9:15 PM

#

that doesn't sound right at all

#

It's a 100% freshly installed debian

agile perch Sep 8, 2022, 9:16 PM

#

I mean it’s either a Debian issue or a grub issue

carmine blade Sep 8, 2022, 9:16 PM

#

I'm thinking if installing grub on the second drive was a bad idea, but other than that?

agile perch Sep 8, 2022, 9:16 PM

#

Is your grub on fat32?

carmine blade Sep 8, 2022, 9:16 PM

#

no, it's on btrfs too

agile perch Sep 8, 2022, 9:16 PM

#

Then the grub installed failed

#

You need it to be on fat32

#

Show lsblk -f

carmine blade Sep 8, 2022, 9:18 PM

#

agile perch Sep 8, 2022, 9:19 PM

#

Which one is your EFI partition for grub?

carmine blade Sep 8, 2022, 9:19 PM

#

There's no partition for grub

agile perch Sep 8, 2022, 9:19 PM

#

carmine blade There's no partition for grub

???

carmine blade Sep 8, 2022, 9:19 PM

#

what?

agile perch Sep 8, 2022, 9:19 PM

#

You need a bootloader for your OS, it should be fat32 and on its own partition

carmine blade Sep 8, 2022, 9:20 PM

#

okay... I mean, right. That's useful info. I wish it was written somewhere

#

But also, the installer suggested to use physical drives, not partitions

#

as if it didn't care about partitions

agile perch Sep 8, 2022, 9:20 PM

#

It only needs to be like 300MiB

carmine blade Sep 8, 2022, 9:20 PM

#

so I wans't really choosing a partition

#

I'm not exactly getting this now

#

if I create a separate partition, it will still most likely suggest a physical drive to choose

#

btw can I fix it by creating a partition now and moving /boot there?

#

or do I have to reinstall it all?

agile perch Sep 8, 2022, 9:24 PM

#

carmine blade btw can I fix it by creating a partition *now* and moving `/boot` there?

I think that should work

#

/boot will be the mount point to be clear

#

The partition will be like /dev/sda3 or whatever

carmine blade Sep 8, 2022, 9:24 PM

#

devices are under lvm

#

so I guess i have to shrink my logical volume first

agile perch Sep 8, 2022, 9:25 PM

#

I know nothing about lvm beyond what it means

carmine blade Sep 8, 2022, 9:25 PM

#

I merged the drives into one volume group

agile perch Sep 8, 2022, 9:25 PM

#

Never used it

#

Sounds like shrinking it might be the right thing to do

carmine blade Sep 8, 2022, 9:26 PM

#

carmine blade

that's why here you can see data-da as one partition

agile perch Sep 8, 2022, 9:26 PM

#

Sorry

#

Edited

#

Watching a film and typing from my phone

carmine blade Sep 8, 2022, 9:46 PM

#

okay so I did some crazy stuff

#

I have no clue if it's gonna work but here's what I did

#

I shrank my main volume

#

created a new 300mb volume

#

made it fat

#

copied /boot into /boot-1 (for backup)

#

deleted /boot

#

mounted the volume as /boot

#

copied the content of /boot-1 into /boot

#

I have zero idea if it's gonna work and if what I did even remotely makes sense

#

I feel like it shouldn't work

#

okay this is very discouraging

#

nothing changed

#

like... still the same rescue shell, still the same output for ls

agile perch Sep 8, 2022, 9:51 PM

#

You need to install grub to /boot assuming that’s where the efi is mounted

#

Only the efi should be mounted to /boot

#

Then you should reinstall the kernel

#

And then you should do update-grub

carmine blade Sep 8, 2022, 9:53 PM

#

I mounted the FAT volume to /boot

#

and just copied what was in boot before there

#

mv boot boot-1
mount /dev/data/lvol0 /boot
cd boot-1
cp -r * /boot

agile perch Sep 8, 2022, 9:54 PM

#

I dunno about some of that or why you’d need anything that was in boot

#

But maybe it’ll work

#

Ls /boot and ls /boot/grub

carmine blade Sep 8, 2022, 9:54 PM

#

agile perch I dunno about some of that or why you’d need anything that was in boot

why you’d need anything that was in boot
well... I had grub there... I guess i need it?

#

I mean

#

I had boot as a folder before

#

you said I shouldn't have it on btrfs

#

so I made it fat

#

I have no idea if I did it correctly, though

agile perch Sep 8, 2022, 10:17 PM

#

carmine blade > why you’d need anything that was in boot well... I had grub there... I guess i...

oh I just assumed you'd reinstall grub

#

I think on debian you can just wipe /boot and then do grub-install then reinstall the kernel and then update-grub?

#

I think you'll need to do that because it likely relies on UUID

#

but either way let me know if you've managed to boot or not

#

for grub install you might have to put the /dev/<drive in> by the looks of it like this:
grub-install /dev/sda

#

replace sda with your EFI partition

#

then do this:
grub-mkconfig > /boot/grub/grub.cfg

#

making sure that you reinstalled your kernel

hidden plume Sep 9, 2022, 3:26 AM

#

the EFI partition has to be a plain partition formatted to FAT32. that's the only format that a motherboard's UEFI will be able to read

hidden plume Sep 9, 2022, 3:56 AM

#

/boot (where the kernel images reside) can be on anything that grub supports, though. that includes LVM.

alright, I'll try that. Should I do it all under chroot while being in the mounted hard drive, right?

hidden plume Sep 9, 2022, 6:56 AM

#

grub-install probably needs the hard drive to already have a correctly formatted partition to put grub on

carmine blade Sep 9, 2022, 6:58 AM

#

I have /boot formatted as fat

hidden plume Sep 9, 2022, 7:00 AM

#

the command you need would be grub-install --target=x86_64-efi --efi-directory=boot --bootloader-id=GRUB

#

make sure to cd / first

carmine blade Sep 9, 2022, 7:01 AM

#

x86_64
haha ~~naive~~

thanks, I'll try

carmine blade Sep 9, 2022, 7:01 AM

#

btw is it possible that i have problems with booting because it's 32bit?

hidden plume Sep 9, 2022, 7:02 AM

#

no idea

#

carmine blade Sep 9, 2022, 7:02 AM

#

For IA32 (32-bit) UEFI systems (not to be confused with 32-bit CPUs), replace x86_64-efi with i386-efi where appropriate.
wait... can you have 64bit UEFI and 32bit CPU?

#

actually wait

#

UEFI... isn't it a new thing?

hidden plume Sep 9, 2022, 7:04 AM

#

carmine blade Sep 9, 2022, 7:05 AM

#

yeah, I wonder if my netbook has it

hidden plume Sep 9, 2022, 7:06 AM

#

UEFI requires the firmware and operating system loader (or kernel) to be size-matched; that is, a 64-bit UEFI firmware implementation can load only a 64-bit operating system (OS) boot loader or kernel (unless the CSM-based Legacy boot is used) and the same applies to 32-bit. After the system transitions from "Boot Services" to "Runtime Services", the operating system kernel takes over. At this point, the kernel can change processor modes if it desires, but this bars usage of the runtime services (unless the kernel switches back again).[31]: sections 2.3.2 and 2.3.4 As of version 3.15, the Linux kernel supports 64-bit kernels to be booted on 32-bit UEFI firmware implementations running on x86-64 CPUs, with UEFI handover support from a UEFI boot loader as the requirement.[32] UEFI handover protocol deduplicates the UEFI initialization code between the kernel and UEFI boot loaders, leaving the initialization to be performed only by the Linux kernel's UEFI boot stub.[33][34]

#

if you need to install it for BIOS instead of UEFI then i don't have any experience, but that arch wiki page has instructions for that as well

carmine blade Sep 9, 2022, 7:17 AM

#

Thanks. I'll try, but I feel like this is a wrong way

#

because it's a completely new install

#

so I either messed up something while installing, which can be easily fixed by reinstalling

To be honest a reinstall seems like the best bet

carmine blade Sep 9, 2022, 9:42 AM

#

agile perch To be honest a reinstall seems like the best bet

I agree. Already in the process of reinstalling. This time I'll pick /dev/sda for grub, instead of /dev/sdb

#

I think it's fourth time I'm installing Debian, and fourth day in row

#

btw, fwiw I once succeeded installing Debain and booting into it

#

That's when I just mounted sda as / and sdb as /home

#

However that install lacked non-free firmware, and it was a netinstaller

agile perch Sep 9, 2022, 9:44 AM

#

I assume Debian can work out the best grub for you to install

carmine blade Sep 9, 2022, 9:44 AM

#

so it didn't get me any DE or even working wifi

carmine blade Sep 9, 2022, 10:08 AM

#

I prefer neither of those tbh

#

gnome isn't gonna work not as shit on this calculator

agile perch Sep 9, 2022, 10:08 AM

#

so did you just select SDA from that grub screen or did you go back for partitioning?

carmine blade Sep 9, 2022, 10:08 AM

#

former

#

with sdb doesn't work, with sda worked

#

no clue

agile perch Sep 9, 2022, 10:08 AM

#

are you on the same LVM setup?

carmine blade Sep 9, 2022, 10:08 AM

#

Yes

agile perch Sep 9, 2022, 10:08 AM

#

interesting

carmine blade Sep 9, 2022, 10:09 AM

#

#

no grub partition

agile perch Sep 9, 2022, 10:10 AM

#

where is grub??

#

yeah...

#

that's super confusing

I don't understand

carmine blade Sep 9, 2022, 10:10 AM

¯_(ツ)_/¯

agile perch Sep 9, 2022, 10:10 AM

#

I hope your USB stick isn't grub 😂

carmine blade Sep 9, 2022, 10:11 AM

#

lol

#

but no, it booted after I ejected the stick

agile perch Sep 9, 2022, 10:11 AM

#

actually I kind of hope it is, that'd be hilarious

#

ahh okay

#

I don't understand at all. and I'm going to ask in #tech-general

uninstall gnome, TTY, install what you wanted to

carmine blade Sep 9, 2022, 10:13 AM

100%

that's what I wanted

agile perch Sep 9, 2022, 10:13 AM

well, TTY first actually

carmine blade Sep 9, 2022, 10:13 AM

#

I thought Debian Desktop environment would be something more ... innocent

#

but it's fucking gnome 😆

carmine blade Sep 9, 2022, 10:30 AM

#

seems like I have hw issues

#

basically I was just running nano, it worked fine

#

then I exited it

#

now every command yields "input/output error"

#

ig it's just the disk is dead harold1

#

it explains why it froze

#

or, another option ; when it froze and I hard powered off, is when it broke

#

broken disk explains the failure of windows too

#

this doesn't look good either

agile perch Sep 9, 2022, 10:44 AM

#

I dunno, that looks like gnome issues again maybe?

#

but maybe sdb has bad sectors?

#

maybe it's an LVM issue?

#

I don't know

carmine blade Sep 9, 2022, 10:48 AM

#

agile perch I dunno, that looks like gnome issues again maybe?

nay

carmine blade Sep 9, 2022, 10:48 AM

#

agile perch but maybe sdb has bad sectors?

that could be, running a check right now

#

it feels like one of the drives is half-dead

#

all the symptoms:

Windows XP (which was installed before) froze last time I used it
I powered it off, now it became corrupt
Debian live and OpenSUSE live don't start due to some kernel error
Now installed Debian froze
I powered it off, it became corrupt

#

it found no bad blocks

#

I have no idea what's going on

agile perch Sep 9, 2022, 11:19 AM

#

have you done a RAM check?

carmine blade Sep 9, 2022, 11:25 AM

#

agile perch have you done a RAM check?

not yet
though it doesn't feel like it has something to do with ram
but maybe

#

a bit later though, I'm a bit exhausted atm XD

carmine blade Sep 9, 2022, 11:41 AM

#

alright whatever, started memtest86, let's see (it's gonna take hours though)

agile perch Sep 9, 2022, 11:44 AM

#

this is a laptop or a desktop out of interest?

#

looks like a laptop...

#

how easy are the drives to replace?

#

kinda wondering if you could test the SSD's out in another computer

#

if the RAM is fine, could you just put your /home on one drive and keep the root and grub on another instead of doing an LVM?

carmine blade Sep 9, 2022, 11:45 AM

#

Well, I booted from another linux and ran badblocks on both drives, no bad blocks it found

agile perch Sep 9, 2022, 11:45 AM

#

I don't know how LVM works properly, I wonder if the computer is just too old to do it well, if that's a thing?

carmine blade Sep 9, 2022, 11:46 AM

#

agile perch if the RAM is fine, could you just put your /home on one drive and keep the root...

that's how I did initially. It worked until it ran out of space (and it did so like ten minutes later, because desktop Debian consumed 3.5gb out of 4). However, I don't know if it would work stable

carmine blade Sep 9, 2022, 11:46 AM

#

agile perch I don't know how LVM works properly, I wonder if the computer is just too old to...

¯_(ツ)_/¯

#

LVM is a very neat technology, but no clue how it works

agile perch Sep 9, 2022, 11:46 AM

#

no offense intended in how I phrased the question in #tech-general

carmine blade Sep 9, 2022, 11:47 AM

#

ik it's a calculator

agile perch Sep 9, 2022, 11:47 AM

#

can it run skyrim?

carmine blade Sep 9, 2022, 12:00 PM

#

well now it can't run anything

#

from hard drive

agile perch Sep 9, 2022, 12:09 PM

#

how wedded are you to btrfs?

#

I'd suggest maybe moving away from LVM, and just mounting SDB as a secondary drive, and also using ext4 instead of btrfs, in case it's related to how old your hardware is

carmine blade Sep 9, 2022, 3:10 PM

#

agile perch how wedded are you to btrfs?

I'm not, just wanted to try it out

agile perch Sep 9, 2022, 3:13 PM

#

carmine blade I'm not, just wanted to try it out

try ext4, if that doesn't work try ext3 😂

carmine blade Sep 9, 2022, 3:15 PM

agile perch try ext4, if that doesn't work try ext3 😂

I just found another laptop, much more modern 64-bit one. Guess I'll go with that one

agile perch Sep 9, 2022, 3:16 PM

sounds like a smart idea

#

also don't use LVM unless you have a reason to

carmine blade Sep 9, 2022, 3:16 PM

#

why not floshed

#

because I'm about to

agile perch Sep 9, 2022, 3:18 PM

#

because you're just over-complicating things and it'll likely lead to more confusion if and when you need to fix your computer

#

just mount your secondary drive in the fstab and it'll mount each time you boot

carmine blade Sep 9, 2022, 3:19 PM

uhhhh

#

this time the drives aren't small

#

but there are still two of them

#

:|

agile perch Sep 9, 2022, 3:19 PM

#

I don't see what that's related?

carmine blade Sep 9, 2022, 3:20 PM

#

agile perch I don't see what that's related?

I need LVM to merge drives

agile perch Sep 9, 2022, 3:21 PM

#

but why do they need to be merged? why can't you just mount one to the other?

carmine blade Sep 9, 2022, 3:21 PM

#

agile perch but why do they need to be merged? why can't you just mount one to the other?

because I don't want to end up with one of them full and the other one 1/3 used

#

like it always happened to me back on Windows

agile perch Sep 9, 2022, 3:21 PM

#

okay, your choice
