I installed arch only with CLI(like installing Arch) with btrfs and everything works fine. But every time I turn GRUB shows me an error which says that a sparse file is not allowed, I looked in other forums but I could only find solutions for Ubuntu which didn’t work for Manjaro. I have installed Arch-based distributions with btrfs many times and I have never had this problem. Any help would would be great.
Welcome to the forum!
Did you tell GRUB to load the btrfs
module when you installed it?
You should normally be able to remedy that by reinstalling GRUB…
sudo grub-install --recheck --no-rs-codes --modules="btrfs part_gpt part_msdos"
sudo update-grub
If it’s a GPT partition table, then you can omit the part_msdos
module, and likewise if it’s an MBR partition table, you can omit the part_gpt
module.
Thanks for the welcome. But sadly this also didn’t work, maybe you have some other advice?
Yes ─ I’m sorry but I only just remembered that you may need to include zstd
support when reinstalling GRUB for a btrfs
-based system.
sudo grub-install --recheck --no-rs-codes --modules="btrfs zstd part_gpt part_msdos"
sudo update-grub
Also make sure that you add the btrfs
and zstd
module support in /etc/default/grub
, for future reference.
The reason is the grub.env which is on a filesystem not writable by grub and Manjaro grub config defaults to writing the selected entry to grub.env. To work around it edit your /etc/default/grub
and change from
GRUB_SAVEDEFAULT=true
GRUB_DEFAULT=saved
To
GRUB_SAVEDEFAULT=false
GRUB_DEFAULT=0
rebuild grub config
sudo grub-mkconfig -o /boot/grub/grub.cfg
Depending on your requirements you may need to change other settings as well.
Thank you so much this error has been bugging me for quite a while.
