[SOLVED] grub2 dmraid and parttool

Hello,

I want to update from grub-legacy to grub2 and have some troubles to setup
up my grub2 enviroment with dmraid and parttool.
I have installed linux, win xp and win vista on fake a raid device.

On grub legacy I followed the instructions on the wiki as described her  https://wiki.archlinux.org/index.php/In … stall_GRUB
To boot windows xp or vista a hide the windows partitions among each other. With grub-legacy it works. Now the point is how to get this work with grub2.

Currently my grub.cfg for windows looks like following:

	menuentry "Windows XP" --class "windows" {
        insmod part_msdos
        insmod ntfs
        insmod search_fs_uuid
        insmod ntldr        
        parttool (hd3,1) hidden-
        parttool (hd3,2) hidden+
        parttool (hd3,1) boot+
        search --no-floppy --fs-uuid --set root 9084516E84515834
        ntldr /ntldr
}

menuentry "Windows Vista" --class "windows" {
        insmod part_msdos
        insmod ntfs
        insmod search_fs_uuid
        insmod ntldr        
        parttool (dm) hidden+
        parttool (hd3,2) hidden-
        parttool (hd3,1) boot+
        search --no-floppy --fs-uuid --set root 5AFC3ABCFC3A91ED e o
        ntldr /bootmgr        
}

Currently my device.map looks like this:

(hd0)   /dev/disk/by-id/ata-ST3250620AS_9QE254ZH
(hd1)   /dev/disk/by-id/ata-ST3250620AS_5QF5210T
(hd2)   /dev/disk/by-id/ata-ST3500410AS_5VM0FTBY
(hd3)   /dev/disk/by-id/dm-uuid-DMRAID-isw_eafejhhgaf_Volume0
(hd3,1) /dev/disk/by-id/dm-uuid-DMRAID-isw_eafejhhgaf_Volume0p1
(hd3,2) /dev/disk/by-id/dm-uuid-DMRAID-isw_eafejhhgaf_Volume0p2

When try to start windows it complains with

Error: hd3 cannot get C/H/S values

So parttool seems not to work with this configuration.
Windows just starts - but not correct, so my dmraid just works with grub (linux just starting fine, too).
The only point is how must I configure my device.map file that parttool ist working?
A grub console like in grub-legacy to setup the c/h/s values for the fake raid seems not to exist, or I haven't found it currently...

Cheers framas

Re: [SOLVED] grub2 dmraid and parttool

I solved it now by hiding the first disk of my fake raid array. Don't know if this is the "right" solution but it works for me...

device.map:

(fd0)   /dev/fd0
(hd0)   /dev/disk/by-id/ata-ST3250620AS_9QE254ZH
(hd1)   /dev/disk/by-id/ata-ST3250620AS_5QF5210T

grub.cfg:

menuentry "Windows XP" --class "windows" {
        insmod ntfs
        insmod search_fs_uuid
        insmod ntldr
        parttool (hd0,1) hidden-
        #parttool (hd1,1) hidden-
        parttool (hd0,2) hidden+
        #parttool (hd1,2) hidden+
        search --no-floppy --fs-uuid --set root 9084516E84515834
        ntldr /ntldr
}

menuentry "Windows Vista" --class "windows" {
        insmod ntfs
        insmod search_fs_uuid
        insmod ntldr
        parttool (hd0,1) hidden+
        #parttool (hd1,1) hidden+
        parttool (hd0,2) hidden-
        #parttool (hd1,2) hidden-
        search --no-floppy --fs-uuid --set root 5AFC3ABCFC3A91ED
        ntldr /bootmgr
}
