The following is a quick guide on getting basic status LED functionality working with TrueNAS running on the UGREEN DXP4800 Plus. Theoretically, it should work on all models (with some small revisions to the script), but I only have a DXP4800 Plus. :)
This guide is for cron job that runs a script to update the LEDs every couple minutes, but I'm sure the following can be modified for blinky LEDs as well.
- Manually build or download the
ugreen_leds_clitool from https://github.com/miskcoo/ugreen_dx4600_leds_controller. - Plop it somewhere on your NAS (E.g. a dataset).
- In the same dataset, create your
.shscript that controls the LEDs. At the bottom of this gist is my modified version of meyergru's. - Make the script executable:
chmod +X your-script.sh.- You may also need to make
ugreen_leds_cliexecutable as well.
- You may also need to make
- In TrueNas, navigate over to

Thanks to all of you for this. The KITT lights were driving me crazy...lol.
@Weingartens using your script is great for my 8800, but one question. I'm horrible at coding, but I think I see it's set to blink green if there's a problem with the drive, correct?
I ask because my Drive 1 light is blinking green, but TrueNAS doesn't show any smart errors or zfs pool issues, so I'm not sure what I might have done wrong. I'm running 8 spinning NAS drives (mostly Seagate) and an 8800 Plus.
Thought I'd add....6 disks are setup as one pool, 2 are in a mirror pool and the third is a hot spare. The hot spare is set to power down after 10 minutes of inactivity, but all others are always on. Could bay 1 have the hot spare in it and thus be powered down (hence flashing)? I didn't label my disks and can't seem to figure out how to know which one (sda, sdb, etc) is in which bay without shutting down removing one and booting up 7 times to label them all....so...here I am...lol.
Any thoughts?
EDIT/UPDATE: Nevermind.... I shutdown my 8800 and pulled each drive after taking a screenshot of serial numbers and drive names. Then labeled each bay with the corresponding drive name. This lead me to the answer. The drive in bay 1 is the hot spare for the mirrored pool. I'm assuming since it's not a full member of the pool, it shows flashing on the LEDs. That works for me.
Cheers!
