Hey all. I've been having a problem with my RAID setup in Arch. At first Arch wasn't picking up a partition on one of my arrays, (a single large NTFS partition on a 2TB array between two 1TB drives) but after re-creating the RAID array in the Intel Storage Manager I have a different problem. Arch now find the single large partition, but now /dev/mapper isn't populated with the other two partitions on the other array that my operating systems are on (Arch and Windows), when it used to just fine! The only thing I changed was re-creating the partition table on the other array, so I don't know what's going on.
Upon trying to boot, GRUB comes back with the error described on the wiki: https://wiki.archlinux.org/index.php/In … oot_device
However I can't boot into the fallback image either! This means that I can't apply the fix as described in the wiki.
I'm starting to think there is a limitation in Arch where it can only handle a certain number of mapper devices (seems to be 3), or maybe it only detects the partitions on the first detected array? Now that I recreated the partition table on the larger array, it seems like that's the array that's detected first in both a GParted live session and Arch. But in a live GParted session, /dev/mapper was fully populated with all of my disks and partitions... so why is it that Arch can only find the partitions on one of the RAID arrays?
If you guys need any additional information just let me know... I really want to get my Arch setup up and working so I don't have to use Windows all that often (only games that don't work well in Wine).
EDIT: Changed post and title to reflect new problem after recreating the 2TB array

Does anyone know if I can damage my arch install by using mkinitcpio through a Debian live-cd? I'm going to try and use one to remake my initrd by chrooting using this guide: https://wiki.archlinux.org/index.php/In … oot_device
Basically the commands I'm looking to execute would be this:
# mount /dev/mapper/isw_ArchRaidPartition /mnt/
# mount -o bind /dev /mnt/dev
# mount -t proc none /mnt/proc
# mount -t sysfs none /mnt/sys
# chroot /mnt /bin/bash
(edit mkinitcpio.conf according to wiki, inserting the "sleep" hook)
# mkinitcpio -p 3.0-archSo my question is would using the commands from a debian live distro work? I have to use debain since arch live-installs don't detect my arch raid partition, like how I described above. I also can't boot into fallback.
