Package: grub-common
Version: 2.00-19
Severity: normal
Dear Maintainer,
using update-grub to generate grub.cfg the following error happens:
grub-probe: error: unknown filesystem.
and an existing Windows installation on /dev/mapper/pdc_bcbc3 is not
detected fully (see grub.cfg: missing insmod for part_msdos and ntfs).
The problem seems to be the failing of (cf. /usr/share/grub/grub-mkconfig_lib):
grub-probe -t partmap -d /dev/mapper/pdc_bcbc3 # = no / empty result
grub-probe -t fs -d /dev/mapper/pdc_bcbc3 # = unknown filesystem
(On the other hand, the same works fine on a different disk (e. g. /dev/sda4).)
Downgrading to grub version 1.99-27+deb7u2 solves the problem.
