[ubuntu] How do I get Ubuntu to read an existing NTFS partition on a fake RAID?

http://ubuntuforums.org – I have a motherboard with an Intel ICH9R RAID chip. I have an existing RAID 5 setup over three disks which is NTFS formatted. I'm dual booting and I'd like to be able to access the RAID device in both Linux and Windows (and possibly OSX86, if I can ever get the darn thing to work). The problem is, Linux sees the RAID volume as three separate hard disks, rather than as a single RAID 5 device. All of the information I have found so far relates to setting up Ubuntu to boot off the RAID volume, which is not something I need. I just need to be able to access the data from both operating systems. (Hardware)

I want to set up software RAID-1 on my Ubuntu system, and found this example of an /etc/raidtab:

raiddev /dev/md0 raid-level 1 nr-raid-disks 2 nr-spare-disks 0 persistent-superblock 1 device /dev/sdb1 raid-disk 0 device /dev/sdc1 raid-disk 1

I would however like the path to the raid device to be /raid.

Hey I am just looking to set up my family's new computer over this holiday season and I am curious if anyone has some advice on how to setup a 'fake-raid' (raid using the integrated 'raid' feature of a motherboard) to work with both Ubuntu and Windows on a dual-boot machine.

Hoping someone can help...

Here is my setup:

4x Western Digital 1TB drives - 200GB RAID 0 (Windows 7 and Apps / Games) - 1.8TB RAID 10 (Data)

Both arrays use all 4 disks.

Ubuntu has its own 80GB drive (/dev/sde).

I have Dell Poweredge R710 server with PERC H700 Integrated RAID controller. Currently there are 4 SAS 300GB disks in RAID-10 array exposing single volume of 600GB. Server is running VMware ESXi 5.1.

I have 4 new SAS 300GB disks that I would like to add to this server to gain ~ 1.2 TB RAID-10 volume.

I wonder if I can do this expansion without loosing data on existing disks?

A friend's machine running Windows XP refused to boot recently which is running 3 SATA disks on RAID 5 (which was previously upgraded from RAID 1 not by me). I have determined there to be a disk failure. The disks have been replaced many times in the past few years. I wish to backup the RAID5 partition before I try anything to fix it.

In F17 and earlier I have been able to boot from install disk and then ultimately access a raid 1 and then do a custom install. I select a root partition and home partition, etc., and the size of each, always reserving some free space in the volume group that is on top of my raid 1.

In F18 install I can't even see any raid.

Hi guys!

A few days ago, I started upgrading my raid (raid 5) from using 4x1TB to 4x3TB. Never done this before, so it took a while. I replaced the disks one by one and rebuilt the raid in between as I read in some guide. All worked fine, except fdisk complained a little bit about my disks being very large. Didn't think much of it at the time.

I know Linux has great capabilities over the years of using it but I can't seem to find an exact name or setup for this scenario. I want to do Matrix RAID (that is not the correct general name but it was as close as I got) on two HDD. I want to put the OS in RAID 1 for redundancy and then have another partition or folder as RAID 0 for TV recordings both on two HDD.

Hi,

I'm trying to get a windows 7 64bit-ubuntu 64 bit dual boot working onto a dell studio-xps-8100 with an EXISTING raid 0 array with 2 identical 2 tb hard drives with a ich8r/ich9r/ich10r/do/pch sata raid controller. I'm able to install ubuntu but not grub so I'm not actually able to boot into it.
