Samsung SSD 850 Pro smart attribute question:

panorain · December 17, 2025, 3:10am

Hi, I would like to get your insight on the screenshot data attributes of this drive:

Errors show in journal and dmesg with this drive when it is mounted.

I have an old locked post here :< Many 'sas_scsi_recover_host busy' messages are displayed during machine boot

Having followed this everywhere: show output that the errors come from this drive, not from the drive-converter that you mentioned there, but not here.
You cannot expect everyone to follow your posts on various IRC channels, yet you leave out the info here. That’s making things confusing,

Ok, I do not want to make things confusing. I have reattached the Samsung SSD to the Z820. It is the only block device attached at this time. For some unknown reason the kernel sas errors mentioned on IRC, (when the drive is attached with no convertor are not appearing yet).

These errors below in snippet were shown and you probably saw them on IRC (there was no drive convertor in use when they were presented).

# dmesg | grep "error\|warn\|fail"

[    4.343537] [    T745] sas: --- Exit sas_scsi_recover_host: busy: 0 failed: 1 tries: 1
snip

The errors ^above do not appear at this moment. I do not know why (there was no convertor attached when they appeared).

Here is (as of right now) journal:

The drive reports no errors, scsi either.

panorain · December 18, 2025, 6:32am

I am going to reattach the Vantec NexStar SE drive converter and internal CD/DVD combo drive. Then retest (as above). To see if the error status remains the same.

panorain · December 21, 2025, 3:52am

The CD/DVD is connected and also is; The Vantec NexStar SE converter rack is connected; and the errors have returned:

To become more professional I may disconnect the CD/DVD combo drive (and test again)?.. I do not feel it is an issue on the machines BUS. I feel that the NexStar Vantec SE Controller is an issue with the errors ^above.

At the time of this writing the following is presented as output on the machine in question :

The kernel SCSI subsystem remains intact yet the Vantec Controller presents encumbering errors for the kernel to navigate? The kernel overlooks this (runs fine) yet the journal creates entries which are really minor?

Your thoughts are welcome.

-Thank You

Yes, the SAS Layer seems SCSI specific to me and a SSD is not using that so I expect this to be the CD/DVD.

Testing should be easy, just remove the power connector or the IDE/ATAPI connector.

panorain · December 21, 2025, 9:26am

Thank you @marel for your insight, I will remove the

Which I believe is the CD/DVD SATA connected drive (please correct me if I am wrong on this) and then power cycle the machine and show journal output.

panorain · December 21, 2025, 1:47pm

This is something I did not expect. There are no longer SAS errors when # journalctl -b | grep "warn\|error\|fail" is passed. The Vantec Nexstar SE converter is attached. It’s coming from the CD/DVD.

How can a situation like this be mitigated?

knurpht · December 21, 2025, 2:09pm

Could you please look at what you post, Paul? Before posting that is? Now I have to check the entire thread over and over again.

panorain · December 21, 2025, 2:12pm

I apologize for this issue I have created @knurpht. I am excited about the findings in the thread and overreacted once again.

-Thank you kindly

marel · December 21, 2025, 8:44pm

The This is … is attached part is not clear to me.

It looks like you did remove the CD/DVD and the issue is gone. If so it would be good to attach that CD/DVD to another machine to see if it gives also problems there,.
