grub-probe: error: no mapping exists (with encrypted root disk)

[Mario Verbelen]

Binary package hint: grub2

The grub-probe give's a failure with encrypted disk
/boot is not encrypted so the boot is fine, but wheb you want extra stuff like gfxmode it needs files from /usr...

And that disk is encrypted

So I think that I need to move the needed files to /boot and change the grub.d scripts as work around?
coz even when fixing the grub-probe, grub will have a problem at the boot coz encrypted root filesystem

The needed file in this case was /usr/share/grub/unicode.pf2

below a trace for information

[Oliver Dungey (oliver-dungey)]

This is pretty serious. I am running AMD 64 version of Karmic and fixed up my windows XP partition to boot which killed my MBR. Now I am totally stuck as I cannot repair grub2. Every article on fixing Grub leads me to this same problem. I would love to work around it but life is too short and I need my PC back. Luckily I have my files backed up so I am just going to trash Ubuntu and start again but this is very disappointing.

[linas (linasvepstas)]

FYI, I'm hitting something similar, but for mdraid. Now, according to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=540549 my problem was fixed long ago, in grub-1.97, but I'm running lucid, with grub-install -v returning: grub-install (GNU GRUB 1.98-1ubuntu9)

My variant of this bug says:

grub-install /dev/sda
/usr/sbin/grub-probe: error: no mapping exists for `md1'.
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.

grub-install --modules=/boot/grub/mdraid.mod /dev/sda
/usr/sbin/grub-probe: error: no mapping exists for `md1'.
/usr/sbin/grub-probe: error: no mapping exists for `md1'.
/usr/sbin/grub-probe: error: no mapping exists for `md1'.
You attempted a cross-disk install, but the filesystem containing /boot/grub does not support UUIDs.

cat /proc/mdstat

md1 : active raid1 sdc1[3] sda1[0]
      530100 blocks super 1.0 [3/2] [UU_]

i.e. is mdraid version 1.0 and not version 0.9

Th fs itself is ext4

I believe I will be able to work around this by not using raid for the /boot directory, but this is annoying :-(

[Rolf Leggewie (r0lf)]

adressing the problem as reported by the OP, I'd like to point out that I was told today that grub2 from bzr can access files inside an encrypted container. So, this will eventually be fixed. Bear with us.

[Marcus Tomlinson (marcustomlinson)]

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.

[Marcus Tomlinson (marcustomlinson)]

This issue has sat incomplete for more than 60 days now. I'm going to close it as invalid. Please feel free re-open if this is still an issue for you. Thank you.
