[FAILED] Failed to mount /boot after every upgrade

After I run

pacman -Syu

and reboot, system loads in emergency mode:

  [FAILED] Failed to mount /boot.
  See 'systemctl status boot.mount' for details
  [DEPEND] Dependency failed for Local File Systems.
  [  OK  ]...
  [  OK  ]...
  [  OK  ] Started Update is Completed.
  You are in emergency mode. After logging in, type "journalctl -xb" to view
  system logs, "systemctl reboot" to reboot, "systemctl default" or "exit" to
  boot into default mode.
  Give root password for maintenance 
  (or press Control-D to continue):

systemctl status boot.mount

returns

arch linux mount: /boot: unknown filesystem type 'ntfs'

I can fix it by loading from live USB and doing this:

  mount /dev/sda6 /mnt
  mount /dev/sda1 /mnt/boot
  arch-chroot /mnt
  pacman -S linux
  mkinitcpio -p linux
  exit
  umount -R /mnt
  reboot

But what should I do so system does not load in emergency mode after every upgrade?

Re: [FAILED] Failed to mount /boot after every upgrade

Why is /boot an NTFS partition?

Not sure why. Looks like I made a bad choice.

Re: [FAILED] Failed to mount /boot after every upgrade

Yes, but the reason your updates go south is (very most likely) that /boot is (attempted to be) mounted before / - change the fstab order.

The order  of  records  in fstab is important because fsck(8), mount(8), and umount(8) sequentially iterate through fstab doing their thing.

Takeaway: rtfm ;-)

Thanks, didn't know that. It seems that the problem arose only when there was a kernel update during # pacman -Syu. So I'll put [SOLVED] once I've tested. Thank you again!

Re: [FAILED] Failed to mount /boot after every upgrade

The order means nothing because the root dir is mounted in the initramfs before anything else anyway.

The issue is that the "ntfs" driver is read only, so mounting with that driver doesn't let the kernel and initramfs get updated. You need to use ntfs-3g at the very least.

Re: [FAILED] Failed to mount /boot after every upgrade

If I change ntfs to ntfs-3g in /etc/fstab, the system boots in emergency mode again.

Re: [FAILED] Failed to mount /boot after every upgrade

Of course it does, you still have the old kernel and initramfs. You have to fix that first

OK, I see. Could you please point me to the direction how to fix that?

Re: [FAILED] Failed to mount /boot after every upgrade

Rebuilding the initramfs should do.
/me checks whether the install iso has ntfs-3g.

Edit: yes, is.
You should btw, have gotten errors when updating, because the initramfs and kernel and grub config could not be written?

Re: [FAILED] Failed to mount /boot after every upgrade

How do I tell that I want ntfs-3g rather than ntfs during the rebuild? I changed the entry in /etc/fstab and ran mkinitcpio -p linux, but it didn't help.

You should btw, have gotten errors when updating, because the initramfs and kernel and grub config could not be written?

I had warnings like "warning: directory permissions differ on /boot/ filesystem 777 package 755" but not errors if I remember it correctly.

Re: [FAILED] Failed to mount /boot after every upgrade

https://wiki.archlinux.org/index.php/Mk … _and_FILES

You'll probably need all libraries from fuse2 and all libs and exeutables from ntfs-3g.
Also ensure /boot is mounted ntfs-3g.

Alterntaively, you can probably make /boot "noauto,x-systemd.automount" to prevent the initial mount and have it mount on access only.

Re: [FAILED] Failed to mount /boot after every upgrade

There are a lot of proposed hoops to jump through here to work around a problem that is itself easily fixed.

Is this boot partition shared with other OSs?  If not, just make a new ext filesystem and put back the kernel and any bootloader files (either from a backup or from reinstalling them from a live medium).

Re: [FAILED] Failed to mount /boot after every upgrade

rebuilding the initramfs alone won't do anything. This problem is not in the initramfs, either, so adding things do it isn't helpful.

You already know how to fix it, you posted the procedure in post #1.
