update-grub (grub-probe) failed by unknown filesystem.

Hi,
I have trouble.

My distribution is a Manjaro.
The problem occur at update-grub.

$ LANG=C sudo update-grub
[sudo] password for aki:

/usr/bin/grub-probe: error: unknown filesystem.
[1] 21407 exit 1 LANG=C sudo update-grub

I found it on Linux 3.19 kernel installation with Manjaro20150220,
but I think maybe It has already occurred at the time of update to 20150220
because current Linux version is different from Grub menu or print message's version.

disks are:
sda: 120GB SSD : GPT/UEFI Manjaro (automatic layout)
sdb: 3TB HDD : dm-crypt(plain)
sdc: 3TB HDD : GPT/UEFI Windows 7
sdc1:: UEFI
sdc2:: Microsoft Reserved
sdc3:: NTFS(Windows system)
sdd: 3TB HDD : dm-crypt(plain)
sde: 3TB HDD : dm-crypt(plain)
sdf: 3TB HDD : dm-crypt(plain)

sd[bdef] were GPT and sd[bdef]1 were btrfs at I found this problem,
so I think this trouble isn't come from plain dm-crypt disks.

How to fix it?

Regard.

Please post fdisk -l.
Which filesystems are used on the partitions?

yek · 03-10-2015, 06:01 AM

Thank you for your reply. I'm sorry, I did not notice.

fdisk don't report right layout because all disks are GPT and all HDDs are over 2.2TB.

I asked for the filesystem type!

I assume the filesystem for /boot is brtfs, which is not supported by the grub2.

yek · 03-10-2015, 07:23 PM

I just right understood it.

sda1:ext3(BIOS_GRUB)
sda2:vfat(UEFI)
sda3:ext2(/boot)

Code:

$ LANG=C sudo mount | \grep sda >| /tmp/mount
/dev/sda3 on /boot type ext2 (rw,relatime)
/dev/sda2 on /boot/efi type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)

Your partition layout makes no sense.
