06/08/2022, 12:42 PMCould 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?

06/08/2022, 1:35 PMIs this for a Harvester node? Your reference to k3s has confused me

06/08/2022, 3:04 PMoh it changed? iirc, initially it was based on k3s, or maybe I am wrong

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

06/08/2022, 3:22 PMgot 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..
