It looks like 006A has gone bad (actually I don't know which one) and not sure how to proceed from here. I'm trying to move system and appdata out currently, but it's hanging. What's the proper procedure to proceed? Should I be trying to drop the pool to 1 drive?

Btrfs is detecting data corruption on both pool devices, this is most often a RAM issue, run memtest.

If memtest is fine with multiple passes, what do you suggest be done next? 

 

Can I just format the drives and set up btrfs again? Use zfs instead? 

 

I just store cache, docker img, and system apps.

memtest is only definitive if it finds errors, but scrub the pool and post the results.

Memtest passed with 2 passes. Ended up changing to zfs instead on the 2 nvme's and I don't see any disk errors or io delay anymore.
