After updating my headless server I was greeted by this:
error: inode not found
Please press any key to continue…
but pressing any keys didn’t do anything (and the lights of my keyboard went off). Because grub was working, I was able to select a different BTRFS snapshot (by pressing Shift during boot). But retrying the update from my latest snapshot results in the same issue.
Fix:
GRUB/Restore the GRUB Bootloader - Manjaro did work. Because I’m using BTRFS (and not ext4), one NVME drive (and not multiple or SATA SSDs) I could executed these commands in an Live OS:
su
mount -o subvol=@ /dev/nvme0n1p2 /mnt
mount /dev/nvme0n1p1 /mnt/boot/efi
manjaro-chroot /mnt /bin/bash
pacman -Syu grub
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
grub-mkconfig -o /boot/grub/grub.cfg
My system is working again but I was not able to find the real issue. I create this topic for other users running into this same issue
