I'm wondering if there is a way to install Mac OS High Sierra using terminal onto a specified drive?
I'm working with a bit of a unique situation as I've been running Mac OS Sierra successfully in a RAID0 setup on a 15' 2011 MacBook Pro. I've swapped the SATA-connected optical drive for a second internal SSD for maximum read and write speeds.
When I attempt to go through the installation process for High Sierra, I boot into recovery mode with High Sierra already installed on an external drive and the two freshly erased and partitioned internal SSDs in Mac OS Extended (Journaled) format. I then combine both of the internal drives I wish to use in the RAID0 format with Disk Utility's RAID Assistant. After successfully combining and mounting the drives, I return to the High Sierra Installer to attempt to install the OS on the RAID0 drive. I'm given the error 'You may not install to this volume because it is part of a AppleRAID.'

My hunch is that because the High Sierra installer automatically converts internal drives during installation into the new APFS, rather than using Mac OS Extended (Journaled) format, it may not be able to do this with a striped RAID virtual drive. I'm able to format both individual SSDs into the APFS format using Disk Utility but when combining the drives using the RAID Assistant the only option is to erase and combine using Mac OS Extended (Journaled).
