It appears that software RAID may be possible for a dual boot Fedora9/WinXP: <a href="http://www.overclock3d.net/articles.php?type=3&id=51&page=1&desc=dual_boot_raid_windows_and_linux">http://www.overclock3d.net/articles.php?type=3&id=51&page=1&desc=dual_boot_raid_windows_and_linux</a> But I was hoping to have a RAID 1 setup and not RAID 0 unlike the guide. Could this be the problem or should it be do-able? Option two: Anyone know of any current motherboard with SATA RAID controller that would support Fedora 9 and windows hardware RAID simultaneously? <div class="gmail_quote">2008/5/20 Sam Varshavchik <<a href="mailto:mrsam@courier-mta.com">mrsam@courier-mta.com</a>>: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="Ih2E3d">Sebastian Gurovich writes: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Are you suggesting that I partition my 2 disks identically and then implement software RAID 1 inside of my Windows XP and linux partitions? </blockquote> </div> No, I'm suggesting that the chances of you getting both Linux and Windows XP working with a RAID configuration on the same set of drives is slim to none. As far as I know, Windows XP does not implement any kind of software RAID. The only kind of RAID I am aware of, that works with Windows XP is hardware or pseudo-hardware RAID. Ordinary, run-of-the-mill RAID controllers ship with Windows XP-specific drivers. Furthermore, the Windows XP-specific RAID device drivers almost always assume that they're going to take control of the disk's entire contents, and you won't be able to carve out a portion of each disk for Linux's soft-WAID. If, and only if, you invest significant time into planning and doing your homework, you may be able to carefully select RAID hardware that's supported by both Windows XP and Linux. You'll need to do your research in advance, and select your hardware only after researching that specific hardware's RAID support in both Linux and Windows XP. But, if you're saying that you already have some random bits of hardware with a "RAID" sticker slapped on it, the chances of you being able to use it in both Linux and Windows XP is somewhat slim.<div class="Ih2E3d"> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Do I only need to install the two OSs on 1 of the two physical disks? </blockquote> </div> Ignoring Windows XP, when installing Fedora, you get an option to set up a RAID partition(s) of your choosing. Subsequently, the installer proceeds normally, and installs itself onto the RAID partition. End of story. Once a RAID partition is set up, it looks like a single, ordinary partition for all practical concerns. One the Windows XP side, what has to happen is that the RAID must be set up before Windows XP gets actually installed. Either Windows XP must have built-in drivers for the RAID hardware, or the hardware must provide a device driver disk, and instructions for loading the device driver when installing Windows XP. -- fedora-list mailing list <a href="mailto:fedora-list@redhat.com">fedora-list@redhat.com</a> To unsubscribe: <a href="https://www.redhat.com/mailman/listinfo/fedora-list" target="_blank">https://www.redhat.com/mailman/listinfo/fedora-list</a> </blockquote></div>
