Talk:Installing with Fake RAID
Grub without chroot?
Could GRUB be installed without chroot? Probably easier to do a pacman -U /pathToPackages/grub* followed by grub-install /dev/mapper/raidSet and skip chroot and the graphical bootloader installation. -- Loosec
Determine number of root devices
I was getting the "major/minor" error, as detailed at the end of the page. Should be noted (I pulled a fair bit of hair out until I figured this out) that you need to use pacman to install dmraid before you can include it as a mkinitcpio hook, so that it can work.

- You are free to try and add it yourself, don't be scared of the wiki :) -- Kynikos 06:02, 15 August 2011 (EDT)
Out of date page? (use mdadm instead of dmraid)
Intel RST (Rapid Storage Technology) recommends using mdadm rather than dmraid for fake raid.
- My Intel (ISW) raid would get detected by dmraid but fails to detect my partitions. After installation of Arch and rebooting it would not even detect anything anymore. Seems like many user on all kind of Linux distributions have their problems with dmraid. HOWEVER, mdadm works perfectly fine. My raid now shows up at /dev/md126 and /dev/md127 or /dev/md/<NAME>_0 and it' partitions at /dev/md/<NAME>_0p1 ...
- Not sure why not to use mdadm. My system now has access to it's raid via Linux and Windows.
- Thought I might write this down, in case someone has problems with dmraid, that mdadm might be the answer he is looking for.
- So set USEDMRAID to "no" in your /etc/rc.conf, reboot and look out for /dev/md*.--Spezifanta (talk) 10:32, 5 June 2012 (UTC)
