Install SolusOS with software raid0 /home device
I don't know if this is correct or not, but it's working for me.
First, torrent/download the latest iso and write it to a thumb drive with ddrescue
ddrescue -D --force Solus-1.2.1.iso /dev/sdX
On my machine you can write the thumb drive using USB 3, but you have to
afterwards move the thumb drive over to a USB 2 port to uefi-boot. At boot
time on Asus X99 mobo, tap the f8 key for boot device menu, and select uefi-usb.
The SolusOS installer will insist on formatting the / partition, so back that up,
and then mdadm is not installed so you will have to install that.
eopkg install mdadm
If you need to create your software raid device, the Arch Wiki
is a great resource, but you'll at least need to assemble the raid.
mdadm --assemble --scan
Now you can run the installer gui application, and select the raid device as your home partition. But afterwards
there is some additional configuration you'll need to do via chroot. Mount your / device and chroot into
it.
mount /dev/sdxY /mnt
or in case of nvme / device
mount /dev/nvme0n1p1 /mnt # (or similar)
and then perform chroot
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
chroot /mnt
and then install and set up mdadm
eopkg install mdadm
mdadm --detail --scan >> /etc/mdadm.conf
and then you might want to adjust fstab
# UUID=0421c6.......dd6ecc7 /home ext4 discard,rw,relatime,errors=remount-ro 0 2
UUID=0421c6.......dd6ecc7 /home ext4 rw,relatime,stripe=256,data=ordered 0 2
There doesn't seem to be an update-initramfs commmand available, so not sure if raid / device is possible.
