Hi,
I bought a Vaio Z. It has 2 hard drives of 128 and they are setup with
a fake RAID 0 " Intel Rapid Storage Technology " . That makes a RAID 0
of 256Gb.
I have no experience with RAIDs and I am trying to install wheezy but
also to keep windows.
I would like to keep the windows system. I made some space and I am
able to go through the installation process but when I try to
partition the hard drive I get:
Failed to create a file system
The ext4 file system creation in partition #6 of RAID0 device #126 failed
I created the partitions... but I also got that message. Any ideas? It
seems that the installer was able to create the partitions but not to
create the filesystem.
I read in Julien Danjou's blog that the Intel Rapid Storage
Technology's RAID does not work properly with Linux.

I would like to keep windows, but Julien suggested to wipe the whole
hard drive. Any suggestions?
Thanks a lot,
Dan

Any ideas why I couldn't install linux in this fakeRAID? " Intel Rapid
Storage Technology " .
I think it is possible to disable the fakeRAID in the Bios. Probably
If I am not able to install linux with Windows using this fakeRAID. I
will just erase windows and install only Linux (Debian) using a
software RAID 0. I think that should be quite straightforward with the
Debian installer.
Thanks,
Dan

Hi Dan,
the good news is that I can confirm that it is possibly to run Linux
on a VAIO SVZ13, using the original Intel-RAID0 and without destroying
the pre-installed Windows. The bad news is that the way I did it is
probably not easy to follow for everyone, and it might require some luck
(i.e. using the correct versions of everything, and in the right order).
Unfortunately I cannot give you precise advice, but maybe telling you
about my experiences installing Linux on this device will be of some help.
However, in my case I did not install Debian Wheezy but Xubuntu 12.04.
For this I had to use Ubuntu's "alternate installer", which I believe
behaves very similar to the Debian installer, although I guess there
are some differences.
But before running any installer, I actualled used a Linux-Live-CD (GRML
2012.05) to back up (using ntfsclone) and shrink (using ntfsresize)
the Windows partitions and to repartition (using fdisk -uc) the
Intel-RAID0. If I recall correctly, the original partitioning was:
p1 = recovery
p2 = Windows boot loader
p3 = Windows 7
p4 = hibernation
I deleted p1 and p4 and shrank p3. Later during the installation, I used
p1 for the Linux / filesystem, and the space gained from p3&p4 for /home.
I do not recall having any trouble creating the filesystems. But if
I had, I would have tried creating the filesystems manually via GRML,
and then telling the installer to simply use the existing filesystems
(which I believe is possible, but admittedely I'm not completely sure).
For me the biggest snag was installing GRUB to the MBR, which requires
giving the correct device name, i.e. /dev/mappers/isw_something or so.
But in the end it worked, and dual-booting between Windows and Linux works
fine so far. As such, I cannot confirm the statement from Julien's blog
that "this kind of RAID is not supported correctly by GRUB".
Another internet resource which might contain helpful hints is this
thread:
http://forum.notebookreview.com/sony/675057-ubuntu-linux-svz1311.html
Hope this helps and good luck,
Frank
P.S. this is the first time I use google-mail to reply to this list,

Thanks a lot for your answer! It is good news that Linux runs in this
laptop. I shrink the windows partition using Windows. I think that
Windows messed up something because I can not even create a ntfs
partition using Windows...
Maybe I can use the Windows copy that comes with the laptop using
virtualbox. I use most of the time linux and not Windows. I am
creating now the rescue DVDs. Windows 7 takes 5 DVDs!!!
Best,
Dan

to
because both the actual partition and the file system need to be
adjusted. After doing this, you should check the partition for errors.
Only then should you try to do anything else.
Using RAID 0 (not really RAID because there is no redundancy) for a
primary file system is a scary proposition. Both drives need to be
working or your system is in deep trouble. Given that disk failures
probably account for the majority of hardware problems, I personally
would try to get rid of the RAID 0 entirely.
To remove RAID 0, you may have to copy your Windows partitions to
another drive temporarily, then try to break the array and copy the
partitions back to just one drive. This means that you need to resize
the Windows partitions so that they fit onto a 128G drive.
Once you have your partitions copied, try booting from a live cd and use
gparted to create new Windows partitions on one disk and Linux
partitions on the other. Copy the Windows partitions back and try
rebooting into Windows. This may actually require reinstalling Windows
(do a repair-type installation so you don't wipe out your other Windows
programs). Don't reformat the disks but do allow Windows to try to
repair them if needed. And keep the copies of the original partitions
until you have this working.
