[SOLVED] grub-probe: error: unknown filesystem

davy_crockett · 2016-01-22 08:09:32

Hi there,

I tried updating my kernel parameters in /etc/default/grub to enable hibernation. However, when running sudo grub-mkconfig -o /boot/grub/grub.cfg I receive the following output:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
Found fallback initramfs image: /boot/initramfs-linux-fallback.img
grub-probe: error: unknown filesystem.
done

My kernel parameters are:

GRUB_CMDLINE_LINUX_DEFAULT="cryptdevice=/dev/md/internal_0p2:system root=/dev/mapper/system-root resume=/dev/mapper/system-swap quiet ipv6.disable=1 radeon.audio=1"

I was going to try and reboot my PC and hibernate and see if hibernation is successful or if the above error is fatal. It still occurs if I take out the resume=/dev/mapper/system-swap as well; and that's how I've always had the kernel parameters. I've also created a new initramfs as well.

Any advice on this error?

Two thing comes to mind: 1) hard-disc encryption 2) is your boot partition is mounted on /boot? Kindly post yout /etc/fstab and output of 'lsblk'.

I found out what it was - I had an external hard drive connected up. With it disconnected it no longer gives the error.

I guess you should be using UUID
