My weekly zpool scrub
came back with this:
pool: blackhole
state: DEGRADED
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.

I only got the drive 6 months ago, well within WD’s 3 year warranty so I opened a support case, but do errors like this basically always mean the drive is its way out or is it possible to have false positives?

Typically, yes. It could be due to either a flaky SATA cable/connection/controller, so you might try moving it to a different port if you are able, clearing the error, and seeing if it reoccurs.
Regardless, just make sure you have a good backup of the data or are confident in the other two disks.
This is the way!
Thanks, I will start a backup now. I don’t have any extra automated backups so I guess this is my wake-up call to figure something out.
Change cable or re seat sata connector, clear errors and start a scrub is what I always do.
