Thread: Mounting Windows Software Raid in Ubuntu

hello all

have computer i'm dual booting between ubuntu 11.04 , win7 (enterprise?)

have sdd i've split oss, , pair of hdd i'd raid0 together. i've read in few places linux should able handle win7's software raid , found helpful post: http://ubuntuforums.org/showthread.p...t=dynamic+disk

ran through instructions got stuck in trying mount drives.

did:
1. load win7

2. set both drives gpt

3. build raid0

4. format ntfs

5. verify works (copied file it)

6. boot ubuntu

7. run: cat /proc/partitions

code:

major minor  #blocks  name       8        0  312571224 sda     8        1       1024 sda1     8        2     130048 sda2     8        3  312440118 sda3     8       32  312571224 sdc     8       33       1024 sdc1     8       34     130048 sdc2     8       35  312440118 sdc3     8       16   78150744 sdb     8       17     102400 sdb1     8       18   38972416 sdb2     8       19          1 sdb3     8       21   39072768 sdb5     8       48  156290904 sdd     8       49  156288000 sdd1     9        0  624880128 md0

8. run: sudo mdadm --build /dev/md0 --chunk=64 --level=0 --raid-devices=2 /dev/sd[c|a][1-3] /dev/sd[a|c][1-3]

code:

mdadm: array /dev/md0 built , started

9. run: sudo mount -t ntfs-3g /dev/md0 /media/raid0

code:

ntfs signature missing.  failed mount '/dev/md0': invalid argument  device '/dev/md0' doesn't seem have valid ntfs.  maybe wrong device used? or whole disk instead of  partition (e.g. /dev/sda, not /dev/sda1)? or other way around?

i've swapped devices around in possible combos (8) , same results each time.

poking around via google bit more, see other have working, i'm hoping there's silly i'm missing.

suggestions?

thanks!

so 'bout half way through posting that, thought "why not try mbr instead of gpt"?

started over, used mbr on disk , received different partition list:

code:

   8       32  312571224 sdc     8       33  312568832 sdc1     8        0  312571224 sda     8        1  312568832 sda1     8       16   78150744 sdb     8       17     102400 sdb1     8       18   38972416 sdb2     8       19          1 sdb3     8       21   39072768 sdb5     8       48  156290904 sdd     8       49  156288000 sdd1     9        0  625137664 md0

the right combo (for me) after was:
sudo mdadm --build /dev/md0 --chunk=64 --level=0 --raid-devices=2 /dev/sda1 /dev/sdc1

seems linux can handle gpt, , can handle ms's dynamic disk (which win uses raid), can't both @ once (at moment!).

i'm mounting , creating files on both ubuntu 11.04 , win 7 , can access them on either os!

hope helps out there.
