Webmin / Bugs / #5120 SMART Drive Information Not Available for NVMe drives, Ubuntu 18.04

Jamie Cameron - 2018-05-03

Does SMART even make sense for NVMe drives, given that they are solid-state devices that can't fail in the way spinning disks do?

There is a bug in Webmin currently whereby NVMe drives are not recognized at all. This will be fixed in the next release though, and should cause them to show up in the SMART module.

I agree it's likely not necessary. But, smartmontools supports it, smartctl returns data, the Webmin system should use it. It currently deosn't. This seems like a bug.

Can you try out the latest development version of webmin from http://www.webmin.com/devel.html and see if it fixes the issue?

Hi, it has some info:

But I would expect something like the output of smartctl:

Perhaps the temps and error status' could be read?

Looks like it doesn't think the drive supports SMART. What output do you get if you run :

smartctl -i /dev/nvme0n0

and

smartctl -H /dev/nvme0n0

Looks like the output from smartctl -i is quite different to what Webmin expects.

Does this system have any regular hard drives in it? If so, what output do you get if you run smartctl -i on one of those devices?

  No, there are no regular hard drives.

  It looks like no SMART information is returned when there are only NVMe
  drives in a system. Smartctl works after telling it to check for NVMe
  drives, but nothing is returned in Webmin.

Is that the full output from smartctl -i /dev/nvme0n1 ? Normally I'd expect to see something in there about whether SMART support is possible, and if it is enabled.

  Yes, that is the complete output. I think this is the "experimental" part of smartctl support.

If you run man smartctl , what does it say the -i flag does?

          and  ATA  Standard  version/revision  information.   Says if the

          rently  enabled  or  disabled.   If  the device supports Logical

          in bytes. (If drive is has a user protected area reserved, or is
          "clipped", this may be smaller than the potential maximum  drive
          capacity.)  Indicates if the drive is in the smartmontools data‐
          base (see ´-v´ options below).  If so, the  drive  model  family
          may also be printed. If ´-n´ (see below) is specified, the power

Odd that when you run smartctl -i /dev/nvme0n1 it doesn't actually say if SMART is supported or not!

Hi
I've encountered similar problem at Ubuntu 18.04 server, and after consulting with smartmontools support I found out that although smartctl -x /dev/nvme0n1 reads only a part of data from drive but gives an error trying to read actual smart data:

Read NVMe SMART/Health Information failed: NVMe Status 0x6002

But if I use , smartctl -x /dev/nvme0the output is full and without errors.

Unfortunately, it doenst help me with Webmin as I cannot change /dev/nvme0n1 to /dev/nvme0 anyway in webmin SMART module.
Any ideas and workarounds are welcome.

I've checked in a possible fix for this here : https://github.com/webmin/webmin/commit/fe3cf26889c8ccf42a445b183a9a304fb8905bac

  Nope, webmin still identifies it as /dev/nvme0n1
  I tried to refresh modules and restart webmin service.
  
  Maybe we can try to hardcode /dev/nvme0 to see if it works, and then see why "IF " doesnt return the correct drive.
  I dont fully understand syntax, so I cant do it myself, pls help

Here is the solution from smartmontools support:
https://www.smartmontools.org/ticket/1134
It requres altering smartmontools source code, however.

What exact output do you get if you run smartctl -i /dev/nvme0 ?

It's the same for both run options: smartctl -i /dev/nvme0n1:

As I said before the problem apperars when it comes to actual SMART data, there is a problem in smartmontools process, see my previous link. I'm not sure something can be done on webmin side.

Jamie Cameron - 2018-11-25

Odd that the output in both cases doesn't include the usual lines like :

SMART support is: Available - device has SMART capability. SMART support is: Enabled

Which version of smartctl do you have installed on your system?

Do you have any non-NVME drives on this system that you can run smartctl -i on ?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Sure, other non-nvme devices work fine.
