Disk Test Failure

I got an error notice that one of my drives failed from my monthly disk scan scheduled job. 

 

Disk test failed on disk in channel 2,  model XXXXXXXXXXX, serial XXXXXXXXXX.

 

But for the life of me, I can't seem to figure out why. Any thoughts on where to look?

Re: Disk Test Failure

The SMART extended self-test failed.  The most likely cause is there's one or more bad sectors on the disk, but that sector hasn't been accessed during normal usage.  Since all the other disks passed, you should be safe to run a scrub, which should expose the error and correct it automatically.

Re: Disk Test Failure

Hi vrspectre,

 

Seems to be working fine for me. Can you send the entire system logs?

 

How do I send all logs to ReadyNAS Community moderators?

You posted SMART stats on the wrong drive.

Re: Disk Test Failure

Counting channels starting from 0, channel 1could be what we'd report as channel 2 counting from 1. One would have to check if the model and serial numbers match the one the alert was about.

If the numbering isn't consistent it'd be better to use a different word for the 1-based info.  Perhaps "slot"?

 

It's not good to create needless confusion on which disk is failing.

Nothing looks wrong with it's SMART stats.

 

Do you see anything wrong on any of the others?  It's risky to resync if there's a failing disk in the array.

Re: Disk Test Failure

How were you able to determine that?

Re: Disk Test Failure

A failed SMART extended self-test is the only thing that will prompt a message like "Disk test failed on disk in channel 2, model XXXXXXXXXXX, serial XXXXXXXXXX".  Your logs also show that the last SMART self-test failed.

Which log file? I poked around, but couldn't find it. I'm just hoping to help myself better next time. Smiley Happy
