Package: grub-common
Version: 1.99-21
Severity: normal
Hello,
It looks that grub-probe have many errors reported, and maybe one of them
is similar to mine, but I cannot find exactly same problem reported.
I have simple configuration with single disk /dev/sda,
and 2 partitions /dev/sda1 (ext3) and /dev/sda2 (LUKS),
on /sda2 I have a LUKS which after giving keys, have a
LVM volume with about 10 logical volumes, including / (ext4).
grub-probe hovewer have some misterious problem with it, involving not
following symlinks:

Why grub-probe fails to follow link? Why it probes /dev/sda and /dev/sda1 when
it is not asked for it? Why this behaviour changed (it is a regression, it was
working without error)?
This is not critical error, because I can still boot system after update-grub,
because this is what is generated in case of this error:
menuentry 'Debian GNU/Linux, za pomocą systemu Linux 3.4.0-rc7-t43-devel-
smp-00106-gb1dab2f-dirty' --class debian --class gnu-linux --class gnu --class
os {
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root 112f7462-0a8b-
4a93-b9e9-03bf35526c98
echo 'Wczytywanie systemu Linux 3.4.0-rc7-t43-devel-smp-00106
-gb1dab2f-dirty...'
linux /vmlinuz-3.4.0-rc7-t43-devel-smp-00106-gb1dab2f-dirty
root=/dev/mapper/sredniczarny-root ro resume=/dev/mapper/sredniczarny-swap_1
thinkpad_acpi.fan_control=1
echo 'Wczytywanie początkowego dysku RAM...'
initrd /initrd.img-3.4.0-rc7-t43-devel-smp-00106-gb1dab2f-dirty
}
And there is also no problem with boot partition:
sredniczarny:~# grub-probe --target=fs_uuid /boot
112f7462-0a8b-4a93-b9e9-03bf35526c98
sredniczarny:~# grub-probe --target=fs /boot
ext2
So, both kernel and initrd can be loaded without problem, also root=/dev/mapper
/sredniczarny-root is actabale, because initrd is able to properly find this
device and open encrypted device + LVM. However, ability to have UUID there
would be best option, and currently it is not automated due this symlink
releated bug.
It may be releated to the fact that grub-probe is trying to also handle
multiple devices setup, and want to know all devices used by it. However, I do
not understand why output would be a different than just following link:
I also doesn't understand why grub-probe even touches /dev/sda , sda1 and sda2!
It was asked explicitly for /dev/something other (like /dev/dm-1), and it still
is the last thing it does. Even more, /dev/sda sda1 and sda2 are opened
multiple times according to strace.
Additional info
sredniczarny:~# cat /proc/mounts | awk '$2 ~ /^\/$/'
rootfs / rootfs rw 0 0
/dev/mapper/sredniczarny-root / ext4 rw,relatime,nodelalloc 0 0
sredniczarny:~# cat /etc/fstab | awk '$2 ~ /^\/$/'
/dev/mapper/sredniczarny-root / ext4 errors=remount-
ro,barrier=1,user_xattr,relatime,acl,commit=120 0 1
Probably converting to UUID based entries here will solve a problem, but still
I do not see why grub-probe fails with simple request when symlinks (and I find
them more human readable and writable than UUIDs) are presented.
Thanks,
Witek
