Cam status: SCSI Status Error

DanP. · May 10, 2021

Hi,

I built my TrueNAS a couple moinths ago, space is (temporarily) about 80% full, but the NAS is only used lighly with SMB.

I get this error about once a week:

Code:

It is always disk5.
Read write cksum is either 0 0 0 or 0 1 0 - never more.
After a scrub it is fine - for a few days.

PSU and SAS controller (Dell H310) are new.

What I've tried:
- mounted a fan on the SAS controller
- cheked and swapped power and SATA connectors (still same cables) for disk5

I will change power and SATA cables next.

Could the SAS controller be faulty and lead to such an error?
Should I replace disk5? SMART has 2 stored errors for that disk.

PDM · May 11, 2021

I hope its just the SATA cable!

DanP. · May 20, 2021

After replacing the SAS/SATA cable, the machine ran smooth for 12 days.
But now the error is back!

Code:

SMART results are good. zpool status has 1 Write error, resilvered 84K.

I just realized the following:
The last few times the error / command was very similar:
(da5:mps0:0:5:0): WRITE(16). CDB: 8a 00 00 00 00 01 01 c8 e8 08 00 00 00 08 00 00

Could it be a defect sector on the drive?
Can I leave the disk installed as long as it's just those single write errors? Or do you recommend replacing that drive?

Thanks

I have an almost identical system as yours and it appears to be a HBA driver issue. I also had mine show that da5, even though another disk was swapped for da5. This looks to be the bug report: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224496

Which model drives are you using ?

Thanks for the note!
There are some workarounds mentioned in the bug report for "slow" disks. Increasing the CAM timeout, adding L2ARC, decreasing memory clock... I'll try some of these and then report back.

I am using 6 x WD Red Plus 6TB drives (WD60EFRX).

I am going to jinx this, but I replaced the mini-SAS cable and I have not seen this error post in days! You might want to try that first before those changes in firmware.

DanP. · Jun 18, 2021

I have replaced the SAS / SATA cable from disk da5 already, but I'll change the other one as well. Maybe it's not related to da5, like in your case.

DanP. · Jul 26, 2021

@Gamji I recently swapped the other SAS ? SATA cable, but unfortunately the error came back. Same error, same disk.
Is yours still running fine?

I'll try those workarounds next...

Gamji · Jul 26, 2021

Oh man, sorry to hear that. I still have not seen this issue since. Grasping at straws here...but one other thing is I'm currently on TrueNAS-12.0-U4. Are you still running TrueNAS-12.0-U2.1?

DanP. · Jul 26, 2021

Yeah, I'm still on TrueNAS-12.0-U2.1. I was just checking the TrueNAS changelog now.
I'm currently running a disk burn-in with badblocks, but I'll update to TrueNAS-12.0-U4.1 as soon as that's finished. Maybe it makes a difference. Hopefully...
Thanks

DanP. · Feb 22, 2022

In case someone else has a similar problem: I got it (mostly) fixed!

I use TrueNAS for my MacOS time machine backups. I accidentally also enabled snapshots for the backup file. In my case that's a 1,4TB file. I guess TrueNAS got confused making an incremental snapshot of the incremental time machine backup file :)
As soon as I deactivated the snapshots for that folder, the errors disappeared (almost completely). Instead of getting the error every other week, it now happens only once every three months.
