Hi gurus,

I have had an email from my system suggesting that I have an error on a disk.
I've not had a disk fail for a few years (in version 11.xx) and the pool status shows HEALTHY.

This is the email message
* Device: /dev/da1 [SAT], 1 Currently unreadable (pending) sectors
* Device: /dev/da1 [SAT], Failed SMART usage Attribute: 1 Raw_Read_Error_Rate.
* Device: /dev/da1 [SAT], FAILED SMART self-check. BACK UP DATA NOW!

Am I an idiot and I missing something here?
(both or one of these statements could be true!)

The output of smartctl (below) for this disk (da1) shows Completed without error.

Run an extended SMART test, the single pending sector may or not be a problem, but the very high raw read error rate is not a good sign, and it went past the threshold in the past, hence the failed SMART check.

Cheers @Johnnie Black ... Back in 702 minutes! I guess that It may have to be a new drive if it fails this yes?

If the SMART test fails with a read error you should replace it, if it doesn't keep an eye on as it's more likely to fail sooner rather than later.

Well, this drive officially PASSED the long Smart text, but the Raw_Read_Error_Rate is a bit high. So I'm doing some work, upgrading the system in a couple of weeks and I will replace the drive then. Hopefully, the drive will hold up for a couple of weeks.

I looked at your SMART report, try running a long SMART TEST, it has been about a year since it has passed one

Power on hours 30457
last SMART TEST 21612

I would replace it because of the pending sector

You could do a long test, and repost report in "code" tags

Have Fun

Sorry for the late reply. It's been a mad month! It probably was grabbed before. I just replaced the drive. It Wasnt worth the risk.
