When I run smartctl -Ai -d megaraid,0 /dev/sda I only get the following output:

I expected to see stuff like Total_Writes_GiB (TBW) or other “Vendor Specific SMART Attributes” I get on other systems, including the SMART log.

How can I get the complete SMART data here? Is it possible to use nvme to show the statistics as it seems to be an NVMe-attached drive? nvme list only shows me the disks not connected through the MegaRAID controller…

    Its in German but I assume you can figure it out ;)

    It’s odd though, normally NVMe drives are not on /dev/sdx (edit: I guess because it is connected through SAS?)

    Edit: Maybe that raid-controller is stripping the SMART data? I have seen that happening with other adapters, but for a raid controller that would be a bit odd.

      As a German? Never :p

      Tried that, but sadly the nvme-cli tool doesn’t have an option for MegaRAID controllers.

      Yes, probably because of that. It’s a U.2 disk.

      Maybe that raid-controller is stripping the SMART data?

      Maybe, but how do I stop it from doing that?
