Package: grub-pc
Version: 1.98+20100804-14
Severity: normal
Tags: d-i
To reproduce: create eg. a RAID5/6 array in Debian installer and furthermore,
partition the array (/dev/md0),
for instance with msdos partition table. Note that if you do NOT partition
/dev/md0 but use the whole device
as an FS container, this problem DOES NOT happen.
Next, choose root file system to be located on one of these new partitions.
I've tried XFS and ext4 with this,
does not affect the behavior.
Continue installation. When grub2 begins to install, it fails with:
/usr/sbin/grub-probe: error: unknown filesystem.
Auto-detection of a filesystem of /dev/md0p1 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
<bug-g...@gnu.org>
The output of that command is:
