weird stuff about grub2
Hey, all,
Recently , I install Mandriva 2010 spring and openSUSE 11.3 in my desktop computer.Now , I hava 4 OSs(3 distros) in my desktop computer
--- Debian Squeeze(/dev/sda1), Debian Sid(/dev/sda10), Mandriva 2010 spring (/dev/sda11), openSUSE 11.3(/dev/sda12) .
root@debian:/etc/grub.d# fdisk -l
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders

Sector size (logical/physical): 512 bytes / 512 bytes

/dev/sda1 1 608 4881408 83 Linux #this partion is mounted on the Debian Squeeze's root (/)
Partition 1 does not end on cylinder boundary.
/dev/sda2 608 851 1952768 83 Linux
Partition 2 does not end on cylinder boundary.
/dev/sda3 * 852 121602 969925632+ 5 Extended

/dev/sda6 4499 8146 29295616 83 Linux
/dev/sda7 8146 9362 9764864 83 Linux

/dev/sda10 109419 115620 49803264 83 Linux # Debian Sid
/dev/sda11 115620 117613 16016742 83 Linux # Mandriva
/dev/sda12 117614 121602 32034816 83 Linux #openSUSE
the bootloader I use to boot all the OSs is the grub2 shipped with Debian Squeeze.After I installed all the OS, I execute the command update-grub
It did probe all the OS ,the output is :
root@debian:/etc/grub.d# update-grub
Generating grub.cfg ...

done
but when I reboot, and chose the Mandriva menu , it doesn't work , something was wrong , the error message just like this:
VFS:cannot open root device "UUID=f4deab0a-b37c-426f-bb35-f997fd2c9940" or unknown-block(0,0)
...
panic +0x5b/0x10b
...
I check the UUID, the /dev/sda11's uuid is ok(at https://gist.github.com/728993 ) ，but the openSUSE can be boot very well.
The config of mandriva (done by the upate-grub) is(the whole grub.cfg is at https://gist.github.com/728991) :
menuentry "linux (on /dev/sda11)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos11)'
search --no-floppy --fs-uuid --set f4deab0a-b37c-426f-bb35-f997fd2c9940
linux /boot/vmlinuz BOOT_IMAGE=linux root=UUID=f4deab0a-b37c-426f-bb35-f997fd2c9940 resume=UUID=23a9b6ac-b275-4066-8223-
b0ad9e0051ea
initrd (hd0,10)/boot/initrd.img
}
menuentry "failsafe (on /dev/sda11)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos11)'
search --no-floppy --fs-uuid --set f4deab0a-b37c-426f-bb35-f997fd2c9940
linux /boot/vmlinuz BOOT_IMAGE=failsafe root=UUID=f4deab0a-b37c-426f-bb35-f997fd2c9940 failsafe
initrd (hd0,10)/boot/initrd.img
I had to write a config in the /etc/grub.d/40_custom :
menuentry 'Mandriva 2010 Spring' {
set root='(hd0,msdos11)'
linux /boot/vmlinuz root=/dev/sda11
initrd (hd0,msdos11)/boot/initrd.img
}
It works .
However ,I was wondering what's wrong with the auto-probe configuration of grub2 (the part of mandriva)
