Could harvester installer support this hardware configuration for the same physical host? using 2 drives (maybe smaller nvme drives) as software raid1 mirroring for k3s install, and then use a few other nvme drives as data pool? is this possible via GUI installer or pxe installer?

Is this for a Harvester node? Your reference to k3s has confused me

yes. I thought harvester node is using k3s kubernetes?

Harvester is RKE2 under the covers

oh it changed? iirc, initially it was based on k3s, or maybe I am wrong

v0.2.0 used K3OS, RKE2 from v0.3.0
Anyway back to your original Q, I'm not sure the ISO allows you to choose multiple drives to configure software RAID (if it was hardware RAID configured through BIOS then installer would see 1 drive). You could then add additional storage post-install. Using config file (PXE, possibly during ISO install) you can specify a data disk but again not sure about software RAID

got it. So we would need some hardware controller for RAID1, meaning normally can't use nvme for OS drive. Does it support multiple NVME drives without hardware controllers, as a pool of data drives? I assume data drives would be handled mainly by longhorn, my understanding for longhorn is that it would store data under /var/lib/longhorn, not sure what kind of RAID it supports..

Might be good idea to ask question via a new issue on Harvester GitHub repo - https://github.com/harvester/harvester/issues/new/choose
