[SOLVED] failed to mount /boot after update

I ran pacman -Syu without errors but when I tried to reboot, I ran into this issue

failed to start cli netfiller manager
failed to mount /boot

I already tried booting to live usb and chroot to /mnt and run:

mkinitcpio -P
grub-mkconfig -o /boot/grub/grub.cfg

and it ran without error, but I still get the same issue when rebooting

I also tried to reinstall GRUB which was successful, but I still get the same issue which is failed to mount /boot
maybe I should reinstall the whole os?

Re: [SOLVED] failed to mount /boot after update

This normally happens if you either had /boot mounted while not needing it or the reverse you didn't have /boot mounted while needing it.

If the live usb steps are the exact steps you took you will have forgotten to mount your /boot to (/mnt)/boot on the live system, what happens if you actually do that and then try to regen the initramfs/reinstall GRUB?

From the chroot, what does a

sudo journalctl -b | curl -F 'file=@-' 0x0.st

give you?

Re: [SOLVED] failed to mount /boot after update

turns out, my fstab has multiple wrong configures which causes the problem, I fixed it by deleting the contents of fstab and reinstalling grub, which led me to another huge problem but it is irrelevant to the topic... and I ended up reinstalling the whole OS
