I awoke this morning to this critical error. Can anyone advise what I need to do. I have 6 2TB WD enterprise drives in RAID Z2 configuration.

Yes, follow this guide first to check for errors. Post the output of "smartctl -a /dev/ada1" in code brackets.

Follow the guide and run a Long test. If the long test passes then I'd say you had something happen to your drive like it lost power (just a guess). I don't see any issues with the drive except that one Short test failure.

EDIT: The reason I say run the Long test vice a Short test is just to run the most through test and fully test your drive out. You could run a Short test if you like since that is only 2 minutes in duration but then also run a Long test to cover your bases.

I ran the long test and it appears to have passed but there were some failures that I don't understand. The output came from smartctl -a /dev/ada1.

Thanks. From the guide I couldn't figure out what this error meant. I thought the drive passed due to the comment in the report, "SMART overall-health self-assessment test result: PASSED".

Do you have any suggestions about what I should do now? Replace the drive? Is it urgent?

I will clarify that in the instructions, thanks for the feedback.

You should run a Scrub on your pool and if there are any data issues, they should be automatically repaired because you have a RAIDZ2 setup. This is more of a "feel good" move right now.

Your drive is not in a critical state right now unless after a scrub it tells you that your pool is degraded. You have time to obtain another drive and replace it per the user manual. If you have any critical/important data, back it up to some other media just for safe keeping until the drive is replaced.

Here is what I'd do from here if I were you based on the single MultiZone Error (ID 200) and the LBA read error...
1) RMA the drive based on ID200 and the read failure (SMART Test Failure).
2) Replace the hard drive as soon as possible if I had a replacement available.
3) If I have to wait on a replacement hard drive, I'd shut down the NAS as a preservation tactic and power it up only if I needed it.

This relates to whether any of the SMART attributes have reached their threshold, not to the results of SMART tests. It's a common source of confusion.

I managed to start the scrub. How do I know when it is done and how do I know if it repaired anything or generated further issues.

Thanks for all the help. This is super.

ZFS is working fine. You have nothing to worry about except you have a failing hard drive that needs replacing.
