[SOLVED] message from the grub underworld

I'm not what you would call a knowlegable deb/dev user (yet, possibly for years to come)

I'm struggling with using 4 distros on alternating days, and to
prevent grub from stepping all over itself I usually limit grubwork
to my go2 distro which for now is Suse. I'm only saying this to
show where the following boot process began :-)

All the /etc/fstabs on all distros use only disk-by-uuid (since I
reluctantly gave up on the use of dev-names). This would suggest
(to me) that there is no reason why dev-names such as /dev/sda2
should ever appear in the said boot process involving any
installation.

YET, on maybe every 10th boot of Devuan up pops the
error shown in the snapshot (sorry, out of focus took with my kodak):

error pasted onto desktop

I *think* the source of the message is Devuan but I ain't sure.

Partitioning is as follows
(1 = Artix, 2=Devuan, 3=Slack, 4=Leap, 5=Tumbleweed)

GPT PMBR size mismatch (1 != 7814037167) will be corrected by write.

All operational OS partitions are regularly backed up with dd so that
I'm not too worried but I would like to get rid of the nuisance, more
importantly maybe some Dev devs would also want to know

cheers




Edit: 2022-02-12
Since my OP I had successive failures and just now I had a double fauilure affecting
two separate installed oS'es on my g73

It does seem like NOT a Devuan issue at all, the other system
just now was Slackware; BOTH failed because /dev/hdb could
not be found. I should have checked how fdisk saw the disk-1
before doing the just previous grub routine, I had not. Interestingly
the Leap system from which the boot was set up booted fine so
that AGAIN does in it seems point to os-prober. So I next
booted into Leap again, this time I did check, the primary disk WAS
/dev/sda, repeated the boot ritual, and all went fine following.

As outlined before ONLY my Suse systems ever see the primary
drive as other than /dev/sda  ...this has to be "IT". At the time
I launch Yast to lay boot code the Leap system is all up. Is systemd
a factor in id-ing disks by dev-name?

Re: [SOLVED] message from the grub underworld

If you're dropped to an initramfs shell then I don't think /etc/fstab has been read. The problem must be with the GRUB configuration. Please share that here along with the output of lsblk -f. Thanks.


To obtain a root shell use su -. Using just su will result in "command not found" messages.

ignore the labels. they're unused residuals

What exactly can I supply under "grub configuration"?   I never opted
for the Dev installation to deploy boot code but I understand that when
Suse sets up the boot it does poll all grub configs (if that option
is checked). Since the cosy days of grub legacy I'm not familiar with
these new files totaling (their sum -1)  too many :-)

Re: [SOLVED] message from the grub underworld

We need to see /boot/grub/grub.cfg from whichever system is controlling the bootloader. You claim this to be "Suse" (openSUSE?) in the OP but if you're not sure run the set command from the GRUB command line to see the configfile variable and it's location.

If that variable isn't listed and you're not sure which system is controlling the bootloader then install the boot-info-script package in Devuan and share the output of

/usr/sbin/bootinfoscript

The output will be lengthy so be sure to use code tags.

Re: [SOLVED] message from the grub underworld

I have 2 Suse systems Leap-15.3 and Tumbleweed, almost all boots are set up using the former (quoting the grub.cfg from Leap). Sometime the boot is set up from Tumbleweed, the two are probably quite similar but I can quote that one too if needed.     

NB. I ran

apt-get dist-upgrade

earlier and got some cautionary remarks at the end about initramfs, could not duplicate just now because there is nothing to upgrade.  I also installed Slackware-15.0 which writes itself an fstab using dev-names. So before so much as the first boot I edited that fstab to show uuids then ran grub on Leap. The resulting boot of Slackware bombed with a kernel panic 'unable to mount root fs', second attempt was manual

set root=(hd0,3)
linux /boot/vmlinuz root=/dev/sda3
boot

and worked fine. THEN I ran grub from Tumbleweed and that worked fine too, with the menu this time.  My primary ssd always shows up as /dev/sda on Artix, Devuan, Slackware but sometimes as /dev/sdb on either Suse system and since this result is variable and so is the OP issue I suspect there might be a connection.

Re: [SOLVED] message from the grub underworld

So the other distributions all have root=/dev/whatever instead of the UUID, which is why the boot breaks — the block device identifier has changed so the correct root can't be found.

I think the best approach here would be to ditch os-prober completely and build your own multi-boot menu using /etc/grub.d/40_custom to call configfile (ie grub.cfg) in each of the distributions.

Here's an example for Devuan:

menuentry 'Devuan' {
   search.fs_uuid f203d9ec-a53c-4f33-ad2a-222cf8f8dbcd
   configfile /boot/grub/grub.cfg
}

Alternatively just build a complete menuentry, like this:

menuentry 'Devuan' {
   search.fs_uuid f203d9ec-a53c-4f33-ad2a-222cf8f8dbcd
   linux /vmlinuz ro quiet root=UUID=f203d9ec-a53c-4f33-ad2a-222cf8f8dbcd
   initrd /initrd.img
}

^ That uses the /vmlinuz & /initrd.img symlinks that always point to the current kernel version so it doesn't need to be updated after kernel upgrades.

Slackware has similar symlinks in /boot/vmlinuz, /boot/vmlinuz-generic & /boot/vmlinuz-huge with /boot/initrd.gz remaining unchanged regardless of kernel version.

The kernel & initramfs images for Artix are unversioned so they can also be called directly with no need to edit after updates.

No idea about SUSE though, sorry.

And to be clear: this is not a problem with Devuan and there is nothing the Devuan developers can do about it.

EDIT: looking again at the documentation you should check /etc/default/grub in the controlling system and make sure this is set:

GRUB_DISABLE_LINUX_UUID=false

^ That should make GRUB use root=UUID= in the linux line. It should be set by default but perhaps you have changed it to true for some reason. Remember to update the configuration afterwards:

# grub-mkconfig -o /boot/grub/grub.cfg

To obtain a root shell use su -. Using just su will result in "command not found" messages.

You mean changed from uuid to dev-name?

I would think that that would be handled on a partition-by-partition basis, more importantly what I don't understand is why on earth the "grub-run" initiated under Suse in this case should not use only the method used in fstab for each partition But I'm not going to get all riled up as I used to when grub2 first appeared :-)


I think the best approach here would be to ditch os-prober completely and build your own multi-boot menu using /etc/grub.d/40_custom to call configfile (ie grub.cfg) in each of the distributions.

Thanks for the effort and the insight, for now I'm not ready to get into it that deep.

Suse does it much the same, actually I used to wish that all distros would use exactly identical vmlinuz and initrd exactly in the same path i.e. /boot to make it easier for people having to boot manually but I gave up a long time ago. I just installed Slackware-15.0 and didn't even know that it has started using and initrd as well, I didn't cite it in the earlier manual boot but it booted anyway.


And to be clear: this is not a problem with Devuan and there is nothing the Devuan developers can do about it.

I didn't suggest it did, just plain didn't know.

The default Suse version uses #GRUB_DISABLE_LINUX_UUID=true so I'm not sure what that would do in real life but I have set it to false and will watch what comes loose over time. I thing Suse's Yast runs grub-mkconfig when doing the boot ritual.

Thanks again!  I'll mark the topic resolved seeing that I have a good idea where the problem might be.

No, I mean that what was /dev/sda when grub.cfg was created has been assigned to /dev/sdb (or another device node) for the failed boot.

But then it wouldn't be possible to keep old kernel versions installed in case of a problem with the new one. Arch attempts to solve that problem by offering both a mainline and LTS kernel package but it's not perfect and there has been some discussion on their mailing lists about moving to versioned kernel images.

Actually their setting must be false by default because the native entries use UUIDs to identify the root partition in the kernel command line. I think the problem must be with os-prober, there are a few old bug reports describing that and I seem to remember a recent post over at forums.debian.net with the same issue. I don't bother with os-prober myself though so I have no experience with it.

I meant those to be links to the latest versions but the links should be uniform and uniformly placed in all distros. Think of someone with 10 distros aboard who wannts to boot manuallly

set root = (hd0,x)
linux /boot/vmlinuz
initrd /boot/initrd
boot

...end of story. If you're using for example initrd.img then it falls apart. Everyone knows which partition (x) they want to boot. Then IF you want some retro kernel you can just enter the numbered equivalents.

I made the edit but yes, probably for nothing. With absolutely no time or inclination to become a grub2 expert I think I will just start booting manually, or maybe explore partition-labels which I hate no less than grub2 because they too are just another form of virtualisation, or maybe study your suggestions  ..but not before September or so :-)

Too bad the grub devs sacrificed the user editable single menu file, it would be too simple (humanized front part  meaning nothing to grub, it's by and for the user; bracketed uuid does not appear in the menu unless user wants it too):

Disk-1_Part-1  Devuan   (uuid=....)
Disk-1_Part-6  Artix    (uuid=....)
Disk-2_Part-3  Slack    (uuid=....)
Disk-2_Part-4  Suse-TW  (uuid=....)

...etc.

Re: [SOLVED] message from the grub underworld

I've raised the topic on the Suse list, but I remain curious why
this particular problem hit only my Devuan installation. The boot
is set up under Suse, the utility is grub2, the victim partition is
#2, Devuan. That's all I really know :-)

I'm not what you would call a knowlegable deb/dev user (yet, possibly for years to come)

I'm struggling with using 4 distros on alternating days, and to
prevent grub from stepping all over itself I usually limit grubwork
to my go2 distro which for now is Suse. I'm only saying this to
show where the following boot process began :-)

All the /etc/fstabs on all distros use only disk-by-uuid (since I
reluctantly gave up on the use of dev-names). This would suggest
(to me) that there is no reason why dev-names such as /dev/sda2
should ever appear in the said boot process involving any
installation.

YET, on maybe every 10th boot of Devuan up pops the
error shown in the snapshot (sorry, out of focus took with my kodak):

I *think* the source of the message is Devuan but I ain't sure.

.....snip

All operational OS partitions are regularly backed up with dd so that
I'm not too worried but I would like to get rid of the nuisance, more
importantly maybe some Dev devs would also want to know

cheers

I just had the first ever successive instances of this on my asus-g73
laptop so I can expand on the issue somewhat.

The missing dev-name was /dev/sda on the first one, but /dev/sdb
on another.  My hunch is that if at boot-time the drive is recognised
NOT as the same device-name that it was when Suse deployed the
boot code to disk root THAT when the proverbial stuff hits the fan. As I
mention elsewhere this instability I have seen only with Suse, the
disk always shows up as /dev/sda under Artix, Devuan and Slackware.

So maybe I should get one of these to do the honors?  Like I said
I'm just a mortal user... I have no other ideas.
