Bug#696484: grub-efi-amd64 + seperate /boot-Partition with btrfs not working
Package: debian-installer
Version: 20121114
I tried to install Debian/testing on an AMD E2-1800 device with UEFI using the
latest snapshot of the daily amd64 Debian/testing netinstall builds. I noticed
that the installation of grub failed, because grub-efi-amd64 couldn't be
installed correctly. The following error message showed up in the logs (sda2
is /boot with btrfs):
/usr/sbin/grub-probe: Error: unknown filesystem.
Auto-detection of a filesystem of /dev/sda2 failed.
Try with --recheck.
If the problem persists please report this together with the output of
"/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v
/boot/grub" to <bugs-grub@gnu.org>
I played around with different partition layouts to locate the error and
noticed that this error always appears when I try to use a seperate partition
for /boot which is formatted with btrfs.
Constrastingly having no seperate /boot-partition, but / formatted with btrfs
works. A seperate /boot-partition with another file system like ext4 works too.
Regards,
Daniel
