Mount vfat - unknown filesystem

Hello,
I was doing pacman -Syu, when  I got system freeze and I had to use hard power-off (these freezes happen very often mostly by firefox + flash).
Then I couldnt launch archlinux, because it doesnt boot /boot folder, because its vfat folder and there is in /sbin/ mount.vfat no more.
What can I do? Biggest problem is that I am not able to use wifi (I dont know why, but my wifi adapter is not detected. It was just fine before this freeze.) and I dont have any ethernet port.

Read your logs and see what was updated and what got cut off mid-update. Complete the process (especially if it is the kernel).

Not a Sysadmin issue, moving to NC...

Sounds like there is a disconnect between your kernel and you kernel modules.

Compare the outputs of uname -a and of pacman -Qi linux
Then look in /usr/lib/modules.

See if they are in agreement as to which kernel version you have installed and report back

Re: Mount vfat - unknown filesystem

I cant complete the process, because I cant connect to the internet.

Kernel and kernel modules are the same version.
In /usr/lib/modules there are modules with same version as kernel.

Re: Mount vfat - unknown filesystem

OK, let me make things clearer.

What is the output of:

uname -r
pacman -Q linux

As ewaller asked, do they match?

Re: Mount vfat - unknown filesystem

ok, so it's not the most common issue.

what happens when you run `modprobe vfat`?

Re: Mount vfat - unknown filesystem

Okay, that is good -- but it invalidates my assumption.  Can you chroot into the system if you boot from your installation media?

Are we to that point already?

Re: Mount vfat - unknown filesystem

If I run modprobe vfat nothing will happen.
BTW why should I chroot, when I am able to use my console? Because of wifi?

Re: Mount vfat - unknown filesystem

You get no output from modprobe? Can you mount /boot now?

Re: Mount vfat - unknown filesystem

No output and I cant. When I do mount -a, it writes: mount: unknown fs type vfat.

Re: Mount vfat - unknown filesystem

does `lsmod | grep vfat` show that the module is loaded?

Re: Mount vfat - unknown filesystem

Nope...As I said there is even no mount.vfat in /sbin, where other mount programs are.

Re: Mount vfat - unknown filesystem

there is no such thing as mount.vfat

I would reinstall the current kernel. It should be in your cache, so pacman -U /var/cache/pacman/pkg/<pkgname>

Re: Mount vfat - unknown filesystem

The name of the kernel package is "linux". From there, it depends on your version and architecture.

Re: Mount vfat - unknown filesystem

I have there even linux 4.0.2.1...Is it possible?
Okay I have done that, but there is warning: cant create /boot/vmlinuz-linux...Its logical bcs there is no /boot mounted.

Re: Mount vfat - unknown filesystem

No, do not install that without access to /boot. As I said, reinstall the *current* kernel.

Re: Mount vfat - unknown filesystem

Although it wrote these errors, I rebooted and it works just fine now. Thanks you a lot.

Re: Mount vfat - unknown filesystem

Excellent. As long as you have access to /boot and your wifi, make sure to finish the upgrade you started.

And don't forget to mark the thread as solved.
