My Unraid server motherboard recently died suddenly (older used hardware). I've already started building a new one with new, upgraded hardware (new motherboard, CPU, RAM, and chassis). I'll be putting the old data drives (1 parity + 5 data) into the new server, but not sure which drives were which. Does it matter? I've also got some new data drives I'd like to add as well.
Also, my old server used an MSATA cache drive, but the new server will use 2x PCIe NVMe SSDs as the cache drive pool. I've got a 2.5" MSATA adapter that I can use to access the old cache drive in the new server if necessary.
I've still got the USB flash boot drive from the old server. I'd like to be able to boot the new server with my old server's data, appdata, confg, etc. in place. What's the best way to handle this situation?
