Bug#575429: grub-pc: The filesystem containing /boot/grub does not support UUIDs

[Frederic MASSOT]

Package: grub-pc
Version: 1.98-1
Severity: normal


Hi,

On a new machine, I wanted to test the daily-build (Monday 22) of Squeeze installer
for amd64. 

The machine has 2 SATA hard drives, are mounted in RAID1 soft by Linux.
I have a RAID1 partition "md0" to "/boot", the root is mounted on a logical volume,
it uses the same partition RAID1 "md1".

The installation is successfully completed, except for installing the boot loader
grub2 (version 1.98-1).

Through the console, I have this:

# grub-install --recheck --no-floppy --modules="mdraid raid" /dev/md0
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
/usr/sbin/grub-setup: error: no mapping exists for `md0'.


# grub-install --recheck --no-floppy /dev/sda
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.


# grub-install --recheck --no-floppy --modules="mdraid raid" /dev/sda
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
You attempted a cross-disk install, but the filesystem containing
/boot/grub does not support UUIDs.


# grub-install --recheck --no-floppy --modules="mdraid raid
search_fs_uuid" /dev/sda
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
/usr/sbin/grub-probe: error: no mapping exists for `md0'.
You attempted a cross-disk install, but the filesystem containing
/boot/grub does not support UUIDs.


There is this in the file "/boot/grub/device.map":
(hd0)	/dev/sda
(hd1)	/dev/sdb


The matching of UUID and devices is good:

# blkid
/dev/sdb1: UUID="248d7222-1d79-dd61-2766-b0f63e142f70" LABEL="eole2:0"
TYPE="linux_raid_member"
/dev/sdb2: UUID="76644d49-c5f7-9ab6-fe74-81c94fa9616e" LABEL="eole2:1"
TYPE="linux_raid_member"
/dev/mapper/VG0-swap: UUID="88469241-b7d3-4e85-97b5-d33a56bfd2fd"
TYPE="swap"
/dev/sda1: UUID="248d7222-1d79-dd61-2766-b0f63e142f70" LABEL="eole2:0"
TYPE="linux_raid_member"
/dev/sda2: UUID="76644d49-c5f7-9ab6-fe74-81c94fa9616e" LABEL="eole2:1"
TYPE="linux_raid_member"
/dev/md0: UUID="157deef1-ea8f-4611-9021-5e2fabcd84cf" TYPE="ext3"
/dev/md1: UUID="rNyfNa-5mXA-Ne77-Z15k-KpWA-kFzL-nZbp3h" TYPE="LVM2_member"
/dev/mapper/VG0-root: UUID="6e5c349c-d880-4329-a15c-e192aee4954a"
TYPE="ext4"


The file "/etc/fstab" (created by installer) contains:
/dev/mapper/VG0-root    /    ext4    errors=remount-ro    0    1

UUID=157deef1-ea8f-4611-9021-5e2fabcd84cf    /boot    ext3    0    2


The command "grub-probe" is no more reassuring:
# grub-probe -d /dev/md0 -tabstraction
grub-probe: error: no mapping exists for `md0'.


I read the bug report #554790 on Grub2 and UUID, but it is February.

Does Grub2 (version 1.98-1) manages UUIDs?

I was not able to set Grub2 with the "/dev/disk/by-id".


Regards.
