Package: grub-pc
Version: 1.99-27+deb7u2
Severity: important
Dear Maintainer,
I installed wheezy from scratch on my 2 x 4TB server, but I did not succeed
in booting the following configuration on my two drives :
# parted /dev/sda p
Model: ATA WDC WD4000FYYZ-0 (scsi)
Disk /dev/sda: 4001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB bios_grub
2 2097kB 3967GB 3967GB ext4 raid
3 3967GB 4001GB 34.2GB linux-swap(v1)
# parted /dev/sdb p
Model: ATA WDC WD4000FYYZ-0 (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB bios_grub
2 2097kB 3967GB 3967GB raid
3 3967GB 4001GB 34.2GB linux-swap(v1)
At boot time, I land in grub rescue mode with "no such disk" error.
I do not undersand the issue because :
- the installation is OK while not using the second drive + not declaring any raid
- the "grub-install /dev/sda" does not report any error and we can see in its traces:
# bash -x grub-install /dev/sda
...
/usr/bin/grub-mkimage -d /usr/lib/grub/i386-pc -O i386-pc --output=/boot/grub/core.img
'--prefix=(mduuid/2d81babd13f240ec4e10b2c7291977fc)/boot/grub' biosdisk ext2 part_gpt
part_gpt raid mdraid1x
...
which looks fine for me.
