I have a 6-drive setup on RAIDZ2, and when I got a critical alert yesterday I figured I could just find the broken drive and replace it. But I'm a bit confused because it looks like one drive disconnected and a different drive has a lot of errors. I'm not sure if I'm worrying too much about the errors, or if I have multiple failures immanent, or if I'm just reading this all wrong.

zpool status gives me this output:

7c52a93a is my ada3 drive:

gptid/77beff42-4e1c-11e6-bdfb-0cc47acb9984	 N/A  ada5p2

And this is the drive that was disconnected when I first started looking at the system after the critical alert. I rebooted and it showed back up. But at first, I thought ada4 was the drive with the error - I didn't notice 3 was missing at first. So I ran a long test on 4 and It's showing a few errors.

As I understand it, this is the relevant section for ada3:

When I do smartctl -a /dev/ada4, I also see an actual error log talking about register values and a command called "READ DMA" that eventually caused that error, but I'm not sure what to make of this. The entire self-test log for ada4 has Completed: read failure as the Status, while ada3 only has read failures on extended tests.

Please let me know what additional information I can provide - there's a lot of output here and I'm having a hard time figuring out what is relevant.

Don't truncate the output when posting. It helps to have all the information on your drives when trying to troublehoot.

Are you running regular Smart tests on your drives?

I am running regular long & short tests. When I double checked this, I noticed that ada3 is not currently in the selection to be tested, probably because it was removed and re-added. Trying to add it to the drives to be tested via the GUI says "an error occurred".

Here is the full output of smartctl -a /dev/ada3:
