Support for RAID
Created by: barryspearce
Servers are frequently configured using bootable UEFI + RAID + LVM. This was possible under Calamares. Since the demise of that, and the total lack of RAID support in the GUI installers for Manjaro Manjaro Architect should support RAID creation.
At the current time disk partitioning and RAID set creation effectively must be done before starting Manjaro Architect. RAID devices are not shown under the LVM options.
As the software is not RAID aware it shows LVM devices (/dev/mapper) multiple times - one for each disk!
RAID devices should be shown for mounting file systems as well (so you can mount a RAID /boot).
Grub installation (or other bootloader) should also take account of multiple boot partitions when using mirroring. EFI must also be configured for multiple entries in bios when using mirroring.
