I’ve got a 6800 also and I’m just beginning the configuration and testing phase. I’m installing TrueNAS on top of ProxMox. So far just a small hiccup after the initial install of TrueNAS SCALE where the VM didn’t want to reboot. Rebooted the ProxMox base and everything of importance is working now. DHCP gave TrueNAS the correct IP address but TrueNAS didn’t populate default router, DNS, and NTP; so I had to manually configure these.
It seems that the front panel LED’s are controlled by some sort of utility service that UGreen has developed and installed in their base OS. From what I understand, UGreen’s OS is based on Debian, so it should probably work with SCALE if somebody can locate it.
To make things a little simpler, I went ahead and replaced the boot NVME with a new 1 TB stick. That way I can just drop UGreen’s back in if anything comes up.
