Failed to make backup of target subvolume

4xx Client Error 412 Precondition Failed
1

I’m currently trying to repair my Garuda boot after first I didn’t want to boot (Kernel missing), then it didn’t show me snapshots, then I tried to restore snapshots with the live-distro, which worked but it still didn’t boot. Then I went back more and more in that list till btrfs-assistant gave me the error in the headline.

Failed to make backup of target subvolume

After giving the backup some name it worked, but then I got some error I at boot

@/boot/grub/…/normal.mod not found.

The files are in all snapshots. I’ve got snapshots with data and ones without in /@
No inxi, since I can’t boot. I’d just like to know which files to copy where to make it work again.

Boot to the live environment, connect to your network, launch the web browser, and log in to the forum to post the garuda-inxi. It’s not perfectly accurate since it is not the installed system, but it’s better than nothing.

Next, chroot to your installation using the chroot tool in Garuda Welcome, or following the instructions here: How to chroot Garuda Linux

In the chroot, reinstall your kernel. It may be useful to update the system as well, because it sounds like an update may have been interrupted.

Depending on your kernel, that will look something like this:

garuda-update linux-zen

Type exit to get out of the chroot, then try booting the kernel you just reinstalled.

I would like to just copy the files I already have and copy them where I need them to restore some old subvolume which did boot back then.

But I’ll try chroot if I can’t avoid it.

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=garuda --recheck

This fails, due to not having enough disk space. But I do have enough disk space.

update-grub
exit

Check /boot/efi

lsblk -f | grep boot/efi

I am not sure reinstalling the bootloader is needed in this case. I linked that document because it explains how to set up the chroot.

From inside the chroot run this command:

Paste the output into the thread along with the output of garuda-inxi.

lsblk -f | grep boot/efi

It’s empty. grub-install also gives me the disk full problem. I can’t post it, since I’m not on that machine when I’m here in the forum.

In general: Idk, why people assume connecting a live-distro to the network would be so easy that I would do that if I can avoid it, especially since connection through Bluetooth and KDEconnect often don’t work well. So, it would be difficult to get my wifi password over there. That’s an unsolved problem, since live distros don’t have space to put a file into it while it’s being mounted in another system.

All of this requires network connection on my live-distro, which I don’t have.

Use ventoy

sdb                                                                                   
├─sdb1      exfat  1.0   Ventoy   1C24-D355                              10,9G    59% /run/media/sgs/Ventoy
├─sdb2      vfat   FAT16 VTOYEFI  3F32-27F5

Ich lege die Daten unter “Speicher” dort ab, wenn kein dual boot vorhanden ist.

I meant, an empty piece of storage would be good as part of the live distro image file.

I’m on a old version of Garuda with that distro right now anyways. I was hoping I could fix it using that.

Is the EFI partition mounted?

What is the exact error message you are getting?

For most people, it is easy. I guess that is the reason.

What is preventing you from connecting to your network? Presumably you were able to connect to the network from the live environment when you did the initial installation.

I would not expect a forum thread that is completely devoid of any relevant information to go anywhere useful or otherwise be helpful. If you want people to be able to see what is happening on your computer you need to figure out a way to add more information to the thread.

I’m looking into Arch help pages and forums. I don’t think this here will lead to anything.

The error message is about “cannot backup acpi.mod” file. I did’t ask to backup anything. I already stated that efi is mounted, at least indirectly. It’s in boot/efi.

What is preventing you from connecting to your network?

It’s not a router but a mobile hotspot. I would have to configure it and copy the password over.

I found it. The tutorial I followed was wrong. I needed to mount /dev/sda1 to /boot not /boot/efi

Snapper or something else must have messed up something about the snapshots, it looks at @/boot/grub/x86… but there’s no such folder and @ is full while /@/@backup_sosandso still has space.
