Thanks for the assistance. I was never able to get the system to stay up long enough to start the array in maintenance mode. I replaced the motherboard, but was still having the same issue. Thankfully I still had an old AM4 CPU kicking around, so I put that into the system and everything looks stable now. Time to RMA my 18 month old 5700G CPU. Part of my troubleshooting yesterday I replaced my USB, but that one seems to have issue dropping when starting the array (diagnostics attached). I've tried multiple USB ports too. I bought a new key, but now I'm getting an error that I've replaced my USB key twice over the past year and I can't update the key for the new USB key. I opened a support case to hopefully allow me to update the key to either the new USB key or the original good USB that is now blacklisted.

I was able to resolve the issue by going into the RetroNAS Config, going to settings and setting the password. I reused the same password, but it looks like the samba service needs to have the password set after it's installed.
