What is sudo zpool status -v showing for that pool.
Your posted data shows no completed SMART Long tests though. I tried searching the model number online. Is this a refurbished Seagate Exos? I don’t know if the SMART data would be carried over from that or reset.

At a glance the drive looks ok to me so perhaps check the physical connection.

This looks like the issue:

Sense Key : Not Ready
Add. Sense: Logical unit not ready, cause not reportable
I/O error, dev sdb

The drive seems to be temporarily disappearing.

It’s a white label Exos X22.

  pool: Tank
 state: ONLINE
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.

errors: No known data errors

If it was a physical connection issue wouldn’t there be some CRC errors as well?

I would get a replacement in there as soon as possible. Do you have one more SATA and power to add another drive and do an in place replacement of the ‘failing’ drive? With Raid-Z1 and the size of the current drives, that is the safest option.
Raid-Z1 isn’t recommended with large drives due to resilver time and risk of another drive in the VDEV failing. It can be a fine choice, if you have excellent backups and can restore the data for that pool from elsewhere

CRC errors happen when a frame is received but fails the check. Yours is being reset therefore no data no CRC check.

Looks like I want to jump in here for a few minute…

Reading these posts what I see is no SMART Extended Test completed, it is always terminated, this has me asking two question ?

  1. Do you know that it takes a minimum of just over 31 hours to run a SMART Long test on this drive? (1871 minutes = 31.2 hours) This is if there is no NAS activity.
  2. Are you rebooting or doing something to possibly sleep the system?

These very large capacity drives take a long time to test, and if the drive is somewhat full of data, even at 80%, a RESILVER or SCRUB would take a very long time as well. This is a pitfall of very large capacity drives.

You definitely have a pool issue at a minimum, and it may be nothing except clearing the fault indication, but you should test to figure it out.

My advice: Download the Drive Troubleshooting Flowcharts in my signature. Go through it step by step. It is actually pretty easy. Before actually doing anything, make sure you read through it, the Appendix is important data.

What I feel you will end up doing is (from a SSH window, as root):

  1. Type lsblk -n -o MODEL,NAME,SIZE,LABEL,PARTUUID and press Enter. This will list your drives and relevant data.
  2. Look for the matching cb0fa265-44ee-4d45-9512-c78b1dd7ca91 and verify it is in fact drive sdb.
  3. Now that you have verified the drive ID, run smartctl -a /dev/sdb (for the drive identified of course) and then grab the drive serial number, write it down. Always use the serial number as drive IDs can change, and of course will just to mess with your day.
  4. If this is the same drive listed above Serial Number: 00002YDW then I recommend that you first backup any important data you have, if possible. You are only running a RAIDZ1 and with these very large drives, if the data is important then you should be running at least a RAIDZ2, just my opinion of course. This is due to how long it can take to test and RESILVER these drives, if the drive has a lot of data on it.
  5. Now you have a choice to make, run a SCRUB to verify all your data is in-tact, or run a SMART Long/Extended test and ensure it completes. You do have one other choice, if you have a replacement drive, you could REPLACE the suspect drive. But make sure it is the failing drive. I would choose the last option if I had a spare drive and I could not backup my data. It is still a risk either way. Again, RAIDZ1 with very large drives is only smart if the data is not that important or has good backups to cover for a failure.

If you Replace the drive, ensure you check the SCRUB status once the drive has been RESILVERED. Ensure it lists zero problems.

If you SCRUB the pool, first run zpool clear Tank to clear the current faults. Then run zpool status Tank to verify those error ar no longer listed. This does not mean the problem is fixed. Then run your scrub zpool scrub Tank and give it 30 minutes to settle out, then run the zpool status Tank again and get an estimation of the scrub completion time. you can check on that estimation periodically if you desire. One it has completed, run the command one last time to check the status and it should show no errors in an ideal world.

If you run a SMART Long/Extended Test, realize how long it takes. The system needs to remain powered on. You can run smartctl -a /dev/sdb to get a status of the test periodically. You can check if the test aborted early, then try to relate it to something that might have happened.

Good Luck.
