Any way to permanently acknowledge SMART errors?

[technorati]

I have pulled two drives from a system that had some bad/cheap SATA cables in it, and added them to my unRIAD. When I pulled the drives, the SATA cables were obviously coming apart where they mount to the drive, so I was not surprised to find that unRAID alerted me these drives had positive values in "UDMA CRC error count" (12 on one drive, 4 on the other).

 

As I'm pretty confident this was due to the bad linkage they previously had, I'd like to just acknowledge this error, unless those values start increasing all of a sudden. But it seems every time I stop / start the array, I have to re-acknowledge those errors. Is there any way to permanently let the system know "Yep - 12 and 4 are acceptable values for those two drives"?

Click on the SMART status entry on the dashboard for the disk in question and select the Acknowledge option.
 

CRC entries are never actually reset back to zero, but if the value changes again you will be warned.

 

if you are already doing this, then you may have some issue saving the saved state back to the flash drive.

Yes, that's what I'm doing, but it seems to come back and alert me again every time I stop the array or reboot the machine.

Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post.

Other settings seem to stick OK, but here's my Diagnostics.

Syslogs are spammed with 

May  8 12:43:29 juggernaut root: error: /plugins/unassigned.devices/UnassignedDevices.php: wrong csrf_token

Based on that FAQ, I believe this is because there was another computer on the network that still had the unRAID web UI open across multiple reboots. It wasn't clear to me, though, whether you're saying this is the reason that it's not saving the SMART acks?

 

Thanks for looking into this!

So have you tried it again after fixing that problem?

Yes, I am still seeing the SMART status come back to error again intermittently:

 

(I just confirmed there have been no csrf_token errors in my logs since my last reboot)

I have one disk with 2 CRC errors. I acknowledged them long ago by clicking on the "thumbs down" on the Dashboard. Since they haven't increased I don't get any further warnings.

 

Is that what you have done to acknowledge them? Have they increased?

Yes, I clicked the "Thumbs down" icon and chose "Acknowledge" from the menu. The values (UDMA CRC Count) have not increased on the drives, but certain events (stopping the array, rebooting the server) sometimes cause unRAID to alert me again on the same value in the same attribute. No other attribute on either drive shows any indicators of an alert.

From Main, click on a drive to get to its page, then go to the Attributes section. Do any of the other attributes have yellow highlight?

 

I am sure the acknowledged count must be stored on flash somewhere but I don't know the details. Since it isn't happening all the time I wonder if you don't have an intermittent flash problem. When it happens again post new diagnostics.

No - that's exactly what I meant by "no other attribute on either drive shows any indicators of an alert" - the only field in yellow on either drive is that UDMA CRC Count.

Attached is an updated diagnostics.zip from when I had the error this morning.

The yellow highlight will not go away when you access the drives Attributes. It is the Dashboard SMART warning icon and associated Notifications that are supposed to no longer happen once you have acknowledged, until the count increases. Are you still getting those?

 

Nothing obvious in diagnostics that makes me think there is a Flash problem. Has Fix Common Problems ever told you there was a Flash problem?

 

Not ideal, but you can configure each disk regarding which SMART attributes get monitored by clicking on the disk to get to its page, then go to SMART Settings and uncheck the box for the attribute. Of course that means it will never check that attribute again, though you can always take a look at it yourself in the Attributes section as before.

Yes, I'm still getting them - there's a screenshot a few posts above here showing that it came back again this morning.

No, I just ran "Fix Common Problems" and it doesn't report any issues with flash; nor have I ever seen anything in the logs or other notifications suggesting there was.

I'd prefer to live with it, so at least I get notified if the count does increase, indicating that a larger problem exists. Mostly, I was just curious why it would keep notifying me of something I'd already acknowledged, but it sounds like there's not a ready/obvious answer to that.

Are those devices unassigned?

[technorati]

No, they are part of the array.

Acknowledge warnings, grab diags and screenshot of the dashboard, then reboot and more errors appear do the same, then post them all.

I was not sure about the state of my Disk because I did not remember if I hit acknowledge half a year ago, and it did degrade since then or if I did not hit acknowledge in the past.

Because the UI does not tell you the stored values from the last acknowledgement, I did search for the config file.

This topic was listed in the Google search, so I will provide the answer here:
/boot/config/plugins/dynamix/monitor.ini this file tells you the old values and helps you to decide if your disk did degrade significantly or just had a hick up.
I recommend making a copy of this file with the current timestamp because It does not tell you at which date these values got recorded and the extended smart error log does only save errors.
