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

nLEyETn · 11-17-2007, 12:53 PM

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:

 sdb:<7>ldm_validate_partition_table(): Found W2K dynamic disk partition type.
ldm_parse_privhead(): PRIVHEAD version 2.12 (Windows Vista).

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

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

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

nLEyETn · 11-19-2007, 12:51 PM

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

hoodedmanwithsythe · 11-19-2007, 03:07 PM

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

nLEyETn · 11-19-2007, 03:10 PM

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

hoodedmanwithsythe · 11-19-2007, 03:55 PM

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?

nLEyETn · 11-19-2007, 04:56 PM

Cool, thank you very much

, Waiting a little longer won't hurt me any

hoodedmanwithsythe · 11-20-2007, 10:34 AM

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?

Tim/Hoodedmanwithsythe

nLEyETn · 11-20-2007, 02:04 PM

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.

hoodedmanwithsythe · 11-21-2007, 03:34 AM

question is the dynamic disk partition ntfs?

nLEyETn · 11-21-2007, 03:36 AM

Yes it is,

hoodedmanwithsythe · 11-21-2007, 03:42 AM

have you any data on it?

nLEyETn · 11-22-2007, 12:16 AM

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