Sorry if you did it already but I somehow lost track here. Sure. The setup is a single plain partition in an LVM volume. The following commands reproduce the setup (in RAM if /tmp is tmpfs). With a plain LVM volume, the error is the same tough. # tmpfile="$(mktemp)" # echo "${tmpfile}" # truncate --size=$((100*1024**2)) "${tmpfile}" # loop_device_2="$(losetup --show -f "${tmpfile}")" # echo "${loop_device_2}" # vgcreate vg "${loop_device_2}" # lvcreate --name lv -l 100%free vg # sleep 1 # parted /dev/vg/lv --script mklabel msdos # parted /dev/vg/lv --script mkpart primary ext4 4m 100% # sleep 1 # mkfs.ext4 /dev/mapper/vg-lv1 # mkdir /mnt/lv-root # mount /dev/mapper/vg-lv1 /mnt/lv-root # mkdir /mnt/lv-root/boot # grub-install --boot-directory=/mnt/lv-root/boot /dev/mapper/vg-lv ; echo $?
