SMART for sntjmicron, smart-one.cfg

Hi all,

recently got a new USB NVMe enclose with dual NVMe.

Unraid does not recognize any smart information on default auto scan, message is "Unknown USB bridge [0x152d"

CLI smartctl does also not work on auto, however setting -d sntjmicron yields good results, with plausible data.

lsusb shows:

Which looks fine to me and usable SMART info.

How can I make unraid read and use this?

I tried adding the two drives to /boot/config/smart-one.cfg with smType="-d sntjmicron", this sometimes yields temperatures in the UI, but no smart attributes. It also seems to hang unraid for a few seconds here and there with 100% CPU load on a core.

Has someone managed to get this working? I probably need some magical parameters for smart-one.cfg to make unraid able to parse the smart data correctly, but I have no idea what to try. Probably needs some info how to send the smart request and parse it additionally to the device type.

Any help is appreciated!

Maik.
