UGREEN DXP2800 - Cannot Get Linux Installed - rayland - 05-12-2025
Note that this is a cross-post from Reddit r/HomeNAS (I would link but am not allowed). The NAS Compares YouTube channel is what helped me make my decision (thank you!).
Hello all,
I recently purchased a new UGREEN DXP2800. This model has the onboard 32G EMMC storage, 2 NVME slots, and 2 SATA bays. Per the plethora of YT videos regarding installing Linux distros on these units, I have disabled the EMMC storage in BIOS and turned off watchdog. I populated one of the NVME slots with a 1TB Samsung 990 for the OS (way overkill) and the two SATA bays with 6TB WD Red drives. Currently running the 8G of RAM that the unit ships with (it only has a single RAM slot - a new 16G SO-DIMM is on the way).
But here's the kicker - I can't get a Linux installer to run. So far I've only tried TrueNAS Scale and Rocky Linux 9. In both cases, the unit posts and the boot loader of the installation media (USB key) appears. When I try and start the installer for TrueNAS it gets a few pages into loading the live / installer OS and then panics saying it cannot remount root. When I try and start the Rocky installer it is similar - live / installer OS gets a bit in and then halts with errors about not being able to find inst.stage2 / inst.repo.
I'm really scratching my head here as I can't even get a live OS going to begin the install. Videos I've watched and instructions I've read make this install sound like any other typical Linux install (with the exception of disabling the watchdog, which I've done). The only difference is that I've not seen people run through an install on the 2800 (the 2-bay unit) - they've all been on the 4-bay and higher end ones.
I've tried permutations of EMMC enabled and disabled and SATA drives installed and not. Tried different USB ports for the installation media.
Any ideas?

Figured it out... While I tried other USB ports on the device I didn't try *all* of the other USB ports because my mouse and keyboard were populating both of the USB2 ports.
The issue is/was that the USB3x ports aren't supported by the installers I was trying. So the machine would boot off USB3x but once it tried to do the OS handover there were no drivers and that's why the installers couldn't find the "root" device.
TL;DR - use one of the USB2 ports for the USB key and all is well.
