Hi, all.
I have the problem with an installing grub on a mdraid device.
I install a new system with a help of my bootable usb flash. I have x86 system
on the usb flash and want to install a x86_64 system on a hdd. My steps:
1. Boot from the usb flash (/dev/sda);
1.1. Create a raid device on partitions (prepared with fdisk) with:
mdadm -C /dev/md0 -l1 -n2 --bitmap=internal /dev/sdb1 /dev/sdc1
1.2. Make a raid partition and a fs on it:
fdisk /dev/md0
mkfs.ext4 /dev/md0p1
1.3. Install a system:
mount /dev/md0p1 /mnt
debootstrap --arch=amd64 --foreign --include=grub2,mdadm wheezy /mnt
http://ftp.debian.org/debian
1.4. Install grub:
grub --modules="part_msdos raid mdraid1x" --root-directory=/mnt /dev/sdb
grub --modules="part_msdos raid mdraid1x" --root-directory=/mnt /dev/sdc
2. Boot from hdd and get:
error: no such disk.
Entering rescue mode...
grub rescue>
2.1. I do insmod part_msdos, raid, mdraid1x. But when i do insmod normal i get:
error: no such disk.
Now as a workaround i install a system (x86_64) to a different single disk and
booted from it i install a system (x86_64) on a mdraid and do grub-install from
a chroot. And this is work. But this is a strange method.
Can anyone point me to the right section of the
http://www.gnu.org/software/grub/manual/html_node/index.html
to resolve my problem?
Thanks.
