Talk:GRUB/Advanced storage

Booting from RAID Array
This section is all wrong. There is no (more) device.map in /boot/grub2 directory, nor 'grub2-mkdevicemap' command in grub2. The article confuses the MD raid UUID with the filesystem UUID.As far as I know (and I just finished installing 2 such systems) grub2 "just worksTM" with MD raid on linux. Can I go on and delete the section and restart it from scratch?


 * I have to disagree, loading a root partition from an mdadm device did not "Just Work". For one, the mentioned module ("insmod raid") seems to be missing;


 * I could not boot without an initramfs even though both device-mapper (with correct raid levels) and lvm are compiled-in. --Tox2ik (talk) 22:28, 31 January 2014 (UTC)

I agree that the section is wrong. First of all, the  can be used, just have to   or something, and enable that   (and btw, it can all be done in a single call , if you're not using /etc/genkernel.conf to permanently configure mdadm and such for future updates of the kernel. Second,   should be merged first, as noted, yes, but   picks up the correct setup automatically. It inserts the insmods correctly and applies the correct md device UUID for root -- assuming the chroot has been set up that way and / (root) points to the md device to boot the root from. The only thing I had to do was to add   to the   variable. --Gruexyz (talk) 14:22, 26 February 2015 (UTC)
