[gentoo-user] can't find my partition when config grub

[gentoo-user] can't find my partition when config grub

[Chuanwen Wu]

Hi,everybody!
When i used livecd to install gentoo in my HP machine,the error
occured when installing grub:

_map_device_to_grub_device:
Error:could not map /dev/cciss


Use #fdisk -l to get the information of my scsi disk :

Disk /dev/cciss/c0d0

/dev/cciss/c0d0p1        NTFS
/dev/cciss/c0d0p2        Linux
/dev/cciss/c0d0p3        extended
...........................................

Then I try to setup grub by myself.First of all,I copy the grub
directory from my another machine to /boot/,then trid to config
grub.But I found that grub can only detect my first
partition(/dev/cciss/c0d0p1).For example,I can only root (hd0,0),which
is my Windows partition ,but not root (hd0,1) which I want to appoint
as my partition of /boot.

And just now(just several minites before I write this email),I
re-enter grub and now grub can not detect any disk! When I type "root
("+ tab,nothing output.
And when I typed:

grub > root (hd0,1) or  grub> root (hd0,0)

the error is :
Error 21:selected disk does not exitst

When I use livecd to boot up,I use the parameter:gentoo noapic.The
"noapic" is necessary and without it my machine with livecd.

I guess the cause is the Logic Volumn(/dev/cciss/*****).

But how to fix it?

Thank you in advanced!

grub cannot access ntfs so you need to fire the bootloader from windows.
I have no idea what the device /dev/cciss is but grub should help you
with the tab key to find the right notation.

I boot my windows here with:
title Windows
 map (hd1) (hd0)
 rootnoverify (hd1,0)
 savedefault
 makeactive
 chainloader +1

you can forget the map I need it because I swaped my harddisks.
Hope that help a little bit.


Bye
Matthias

My problem is the grub can't find my partition or even disk.So now,
when I press tab key, there is not any notation appearing.That I
think,because grub can't detect my disk.

/dev/cciss is a kind of Logic Volume Manager(LVM).I don't know how
exactly it works.But I know it's different from the LVM2, which I
installed it and use it in my another machine.I heard that the
/dev/cciss is result of some hardware components.But of course, the
LVM2 is implemented by software.
One of their difference is that:I can see and set the LVM in my
machine when the machine even has not enter any OS.When  my  machine
start up, press F8,I can enter a menu in which I can see the LVM and
set it.
But the LVM2,you can only see it after you enter your linux OS.

ps: My machine is a Hewlett-Packard workstation.

It sounds to me like you have a Compaq SmartArray. You CAN get one of 
those to work but you will have to jump through a few hoops. The 
experiences of one person who did it are here:

Thank you.Your link help me a lot!

I install my grub in another way:
First,I write a line "(hd0) /dev/cciss/c0d0" to /boot/grub/device.map.
then :
#grub --device-map /boot/grub/device.map
root (hd0,1)
setup (hd0)
quit
/dev/cciss/c0d0p2 is my /boot partition.

But after I rebooted,the error was:

Invalid system disk
Replace the disk,and then press any key.

Now,I can't boot any OS and can't even enter the grub menu.

TBH, all the machines I have had with SmartArrays have also had a  
simple SCSI or IDE HD for the purposes of booting. It makes life so much 
simpler. ;) Given the low price of IDE HDs these days, you don't need a 
big one, I think I would install one pretty damn quick. ;)


Be lucky,

No, but it's the quickest and easiest way. It will probably save you a 
lot of time and frustration.

Yeah!I can enter grub when I reboot now!!Thank you so much!!!!
You know,last time I used "grub  --device-map=/boot/grub/device.map"
and the result was also "succeeded" and "Done."

It's very wizardly!Now I can boot up just by change the command that
start grub!!
