dbg: SMART is not supported when works with smartctl

root@core:/home/risner # smart -i -d da3
...
dbg: protocol SCSI (specified auto)

dbg: SMART is not supported

But it works:

smartctl -d scsi -a da3

Ideas?

[ctuffli]

I agree, it should be supported. Can you attach the full debug output from the smart command as well as the full output from smartctl -a?

[risner]

I agree, it should be supported. Can you attach the full debug output from the smart command as well as the full output from smartctl -a?

Anything else you need?

[ctuffli]

For SCSI, smart looks for the Informational Exceptions page (ID of 0x2f) to determine if the device supports SMART. Can you add the output from sg_logs?

[risner]

Sure. However I don’t know how to do that?

OK, so the device supports all the pages smart would read if the Informational Exceptions log page existed. If you execute the command smartctl -s on /dev/da3, does sg_logs list the Informational Exceptions page on the non-working disk?

[risner]

Like this?

[ctuffli]

Yes, that is what I wanted you to do, but it didn't add Informational Exceptions to the list of supported log pages. I'm torn here as to how I should fix this. Let me research this a bit and get back to you.

[ctuffli]

I just realized that the sources on github were out of date with the development repo. I just pushed changes to bring the github version up to date. Note that the changes include support for SCSI's Informational Exceptions log page, but given the date you've provided, I don't expect smart to behave differently. That said, it'd be worth verifying this is the case if you have time.

[risner]

I used the one In packages. I’ll check the version tonight.

[ctuffli]

I pushed some experimental changes to the issue-8 branch that report whichever health log pages the device advertises. See if that gets you closer to the result you wanted. Steps would be:

git clone https://github.com/ctuffli/smart.git
cd smart
git switch issue-8
make
sudo ./smart da3
