How do I setup Windows Spanned Dynamic Disks to be used in Linux?

I setup two hard drives in Windows Vista to be spanned together. I want to be able to access them from my Linux, but I cannot figure out how. So far the first thing I have done is setup my kernel with the following options:

Code:

[*] Multiple devices driver support (RAID and LVM)

<*> Device mapper support

[*] Device mapper debugging support

...

...

[*] Advanced partition selection

[*] Windows Logical Disk Manager (Dynamic Disk) support

[*] Windowx LDM extra logging

I am using kernel 2.6.23.1
I have Device-Mapper 1.02.22 installed

The first volume in my span is /dev/sdb1
The second volume in my span is /dev/sdd1

This is the output from "$ dmesg | grep ldm" loading the disk /dev/sdb:

Code:

This seems correct to me so I then try to setup Device-Mapper according to instruction in my kernel/Documentation/filesystems/ntfs.txt

I run "$ fdisk -lu /dev/sdb" which outputs:

Code:

Disk /dev/sdb: 320.0 GB, 320072933376 bytes

255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors

Units = sectors of 1 * 512 = 512 bytes



  Device Boot      Start        End      Blocks  Id  System

/dev/sdb1              63  625140399  312570168+  42  SFS

Then run "$ fdisk -lu /dev/sdd" which outputs:

Code:

Disk /dev/sdd: 320.0 GB, 320072933376 bytes

255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors

Units = sectors of 1 * 512 = 512 bytes



  Device Boot      Start        End      Blocks  Id  System

/dev/sdd1              63  625140399  312570168+  42  SFS

From this info I setup a table file for dmsetup, the table has the following,

Code:

# Offset into  Size of this    Raid type      Device          Start sector

# volume        device                                          of device

0              625140337      linear          /dev/sdb1      0

625140337      625140337      linear          /dev/sdd1      0

I then run "$ dmsetup create newdevice /etc/newdevice1" which gives the following error:

Code:

device-mapper: reload ioctl failed: Invalid argument

Command failed

When I take a closer look in dmesg I find this

Code:

device-mapper: table: device /dev/sdb1 too small for target

device-mapper: table: 253:0: linear: dm-linear: Device lookup failed

device-mapper: ioctl: error adding target to table

I have no idea what is the problem now, can anyone help me with this please.

can you post an
ls of your /dev for me

Sure, thanks for responding, :) I've been messin with this for the past 5 days and I'm getting a little discouraged. Here is the output,

right now I need a copy of your /etc/fstab

Here you go, just so you know, I used to have /dev/sdb1 as a basic disk, so the line I commented out is like that because of how it was previously setup

Code:

/dev/sdc3        swap            swap        defaults                            0  0

/dev/sdc1        /                xfs        defaults                            1  1

/dev/sdc2        /boot            xfs        defaults                            1  2

/dev/sda1        /mnt/windows    ntfs-3g    defaults,uid=0,gid=10,umask=0002    0  0

#/dev/sdb1        /mnt/media      ntfs-3g    defaults,uid=0,gid=10,umask=0002    0  0

#/dev/cdrom      /mnt/cdrom      auto        noauto,owner,ro                      0  0

/dev/fd0        /mnt/floppy      auto        noauto,owner                        0  0

devpts          /dev/pts        devpts      gid=5,mode=620                      0  0

proc            /proc            proc        defaults                            0  0

do you have a /dev/mapper directory? if yes can you post what is in it

Yeah, inside there is just /dev/mapper/control

this may take me some time I need to refresh my knowledge of windows first. it may take me a day to get it to work.
once I have it working I will message you with how I did it.

OK?

Cool, thank you very much :), Waiting a little longer won't hurt me any

It might take me a bit longer I have just got an assignment from college and I will be spending most of my time on this.
It should only take a few days but Don't be too surprised if it takes me a week.
I will keep you posted with an update on my progress each day.
If this is important I can make it a higher priority if you like but that will cause some strains on my time.
Is that ok?

No problem, definitely take care of what you need to before you worry about this. My problem isn't critical, it's just for my own personal pc.

question is the dynamic disk partition ntfs?

have you any data on it?

Yeah, I do, more than would fit on just one drive.
