Comment 16 for bug 681535

I get the same errors. I try to install grub in a chroot environment (dev,sys and proc is correctly mounted with rebind):

"""
$> grub-mkdevicemap
$> grub-install --no-floppy /dev/sda
/usr/sbin/grub-probe: error: no such disk.
Auto-detection of a filesystem of /dev/md1 failed.
Please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to <email address hidden>
"""

The boot partition is /dev/md1 (ext3).

I am using Ubuntu 11.04 (with all current updates installed) and I am using GPT on the hard disks (same partitioning scheme on sda and sdb):

"""
$> parted /dev/sda print

I am using the following grub package version:

grub-common: 1.99~rc1-13ubuntu3
grub-pc: 1.99~rc1-13ubuntu3
