- Annoyance
I am playing around with a USB enclosure. I knew this enclosure didn't report serial numbers or SMART correctly and in the device page it was no surprise to essentially see an empty list under device attributes. But I can download the report manually under Self-Test and query with smartctl.
Then days later, I see some notifications in the WebGUI and emails emails about SMART changes for the fields it's told to monitor:
QuoteEvent: Unraid device dev3 SMART health [199]
Subject: Warning [T1000] - udma crc error count is 1
Description: JMicron_Generic_DISK00_0123456789ABCDEF-0:0 (dev3)
Importance: warning
It even updates the GUI to report an error that I need to acknowledge, with a tooltip showing the specific data that changed, but clicking on attributes again still shows the blank table above.
So clearly unRAID is actually parsing the SMART data and handling changes, but it just doesn't show up under the table. I tried all the different options under SMART controller type. Also it appears the SN does show up under device -> identity, it's just not reportedly normally I suppose.
The model is ORICO 4 Bay Hard Drive Enclosure WS400U3 B0813KKWFJ B08D994JVT with a Jmicron JMB394 and JMS567
I actually spent a bit of time writing scripts that would query the smart data with smartctl, recording diffs, ignoring fields like Power Cycle Count, but seems that wasn't really necessary.
