SMART - Completed: Read Failures

[kmb5405]

Hello,

I built my first server a couple years ago thanks to the community here and everything's been great so far. Recently, I've experience my first alert regarding a HDD:

Code:

Device: /dev/ada2, Self-Test Log error count increased from 0 to 1
Mon, 26 Aug 2019 09:00:38 GMT

The smart data is:

Code:

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

I tried doing some research before posting but only found conflicting information and I'm not sure I entirely understand SMART and how it works. The red flag for me here was the multi_zone_error_rate incrementing to 1. When the alert first came up I thought the drive would try to re-map or flag the bad area and subsequently complete tests but I keep getting the read failures. I have about 130 days left on the warranty on this drive.

Can anyone give me an opinion on this drive?

Thanks!

I have about 130 days left on the warranty on this drive.

If the drive is reporting SMART test failures I would try to replace it under warranty.

Interesting that your results aren't giving the raw values. What do you get when you type smartctl -a /dev/ada2? Also, what is the output of zpool status?

 

[kmb5405]

smartctl -a /dev/ada2 is what's in the OP, the raw values are indented way over to the right for some reason so you might need to scroll over to the right to see.

zpool status:

Code:

root@freenas:~ # zpool status
 pool: FreeNAS-6x3
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
        still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

Ah, you're right. :facepalm:. Based on this post you should replace the drive. You're getting SMART test failures, which is bad, and you're getting > 0 Multi_Zone_Error_Rate, which is bad. This drive is bad and deserves to go back to the manufacturer. :)

 

[cas206]

As a complete newb, myself, here is what sticks out at me:

# 1 Short offline Completed: read failure 60% 20119 1565552088
# 2 Short offline Completed: read failure 60% 19951 1565552088
# 3 Extended offline Completed: read failure 10% 19867 1565552088
# 4 Short offline Completed: read failure 60% 19711 1565552088

I interpret that to mean a disk read failure. So, yeah, what PhiloEpisteme said.

 

[kmb5405]

For anyone coming across this later on, WD replaced the drive under warranty without issue.
