Well, no luck, after a while it disconnected again. I disabled the ACPI in BIOS, it's been stable 1 day.... (versus disconnects every hour).

For what it's worth I had the same issue with my motherboard (Aliexpress BKHD-1264 with Intel N100). This MB has 2 M.2 slots, and the NVMe on M.2 slot0 would disconnect and reconnect periodically. M.2 slot 1 had zero issue. I tried initrd=/bzroot nvme_core.default_ps_max_latency_us=0 pcie_aspm=off and no luck. The only difference between both M.2 slots is slot 0 is also connected to the Intel SATA controller (slot1 is only NVMe). Hotplug was enabled as well so I suspect the SATA controller was messing up with the NVMe SSD So I disabled SATA port connected to the M.2 slot0 on the BIOS, and so far so good.

Ok, so it turns out the drive I was using to test was not working ok. I replaced the drive and inserted 3 fresh drives in the enclosure; now I get all SMART status out-of-the-box; no need to edit /boot/config/smart-one.cfg or configure anything specific in the SMART section of the "Disk Setting" panel. Bottom line, the JMB393 port multiplier form my Ex50 enclosure connected to a JMB582 SATA controller can transmit the SMART data 👌

Hello, I'm quite new to UNRAID but already setting up my second system to backup the primary one. For this I'm connecting a JMB393 based Lian-Li ex50 enclosure configured as port multiplier to a JMB582 SATA controller. Everything works fine, and I see each drive in the enclosure as individual drives in UNRAID. The issue is with SMART, because I only see the temperature of the drives but nothing else. I figured I could get a full smart report using smartctl (full output attached): # smartctl -d jmb39x,4 -a /dev/sdc However I can't find the right configuration to get this display on the UI. I've tried editing /boot/config/smart-one.cfg as such, and running a quick SMART test, but that doesn't seem to change much: [ST2000DM001-1CH164_Z1E3KGFA] smGlue="," smType="-d jmb39x" smPort1="4" smDevice="sdc" Any clue how to proceed ? Thanks smartctl.txt
