[SOLVED] Problems installing on Intel Matrix Raid / FAKE RAID

Using Intel Rapid Storage Technology - Option ROM - 11.0.0.1339

I've created a:

RAID0(Stripe) Strip 32KB Size 214.3GB Status Normal Bootable Yes

Volume which I want to install Arch on.

I've gone through this all the way to a successful install using Fedora (if that is of any help whatsoever)?

So, with Arch, I have read and tried:

https://wiki.archlinux.org/index.php/In … e_RAID_set

As soon as I do a UEFI or BIOS install of Arch and run lsblk I get:

sda-
md126

sdb-
md126

(and using gdisk can create ef00 200M partition and root such as: md126p1 md126p2)

Once I follow https://wiki.archlinux.org/index.php/In … e_RAID_set, and, do:

# modprobe dm_mod

# dmraid -ay

[  39.383447] device-mapper: table: 254:1 striped: Couldn't parse stripe destination
RAID set "isw_dejgjdecda_SSD" was not activated
ERROR: device "isw_dejgjdecda_SSD" could not be found

I am hoping I may end my story here and someone will reply something along the lines of "well, that's because....", and I can continue on my determined attempt to install Arch on this RAID Volume.

However, obviously, I have not just given up at this point, so, some more info just in case it helps:

I can access /dev/md126 in gdisk and use gdisk fully

I can mount/pacstrap/genfstab/chroot/

Then - problems arise - I cannot seem to get the install to boot after having tried either UEFI or BIOS boot using Syslinux, Gummiboot & Grub - always used GPT for the Array by the way.

Any ideas?  Is there a module to load?  I'm still a newbie guys, so, apologies for any glaring mistakes....

Thank you all very much for any help with this.

Frazer.

Replying per your email request.  I have hardly zero experience with fakeraid.  I ran one for a few weeks but then discovered zfs and never looked back.  Sorry dude.
