Comments on Creating A Dual-Boot System On RAID10 (Ubuntu/Windows)
Creating A Dual-Boot System On RAID10 (Ubuntu/Windows) I just bought a new computer and I want to run Ubuntu 8.10 and Vista. I'm really afraid to loose some of my data when a harddrive dies, so I decided to go for a RAID10-setup. Most modern motherboards support RAID0,1,5 and 10. After assembling my new computer, I discovered that the motherboard didn't have a true hardware-RAID-controller. Instead it's just software-RAID, sometimes called fakeraid. If I was installing a Linux-only-system, I wouldn't care and just use the Linux software-Raid options. But this time, my system has to be dual-boot.

I didn't think Linux supported Fakeraid, but it looks like the dmraid package does support about a dozen adapters. I thought it was particularly interesting what you discovered with libparted. I think I worked around this issue in my software Raid 10 howto with a hard link, I'm curious if it works in your howto. If someone is going to try this guide, first try this command instead of rebuilding parted: With your apropriate raid device "ln /dev/mapper/blabla /dev/sde" Then try the installer. Thanks for this bit of knowlege.
I have a Dell XPS 710 with RAID 0 and had this same issue that I fought with for the longest time. Resolved it finally by using the 8.10 Alternate CD which has DMRAID built into it. Found the RAID right way and install was a breeze.

In my installations it was called parted-dmraid, but other than that for now it looks like it is working great .. Thanks.
I Could not install grub using this guide. I got an Error 22.
I first had to correct the hd0 in /boot/device.map to /dev/mapper/isw_bfgggbebhf_diskset
And also edited /boot/grub/menu.lst so that the root devices in the boot options pointed to the correct (hd0,x)
I installed dmraid in the chrooted environment "apt-get install dmraid" and scanned for devices "dmraid -ay"
To disable the faulty patch in Lucid, edit ./debian/patches/series and comment the line 'dmraid.patch'
You also have to comment the line "fix-dmraid-regression.patch". Probably Ubuntu Maverick (10.10)
