Forget this part completely. It doesn't affect raid1. I just re-read
that your setup is not raid1, I don't know why I thought it was raid5.

The likely issue here is that you've got legit corruptions on sda (mix
of slow and flat out bad sectors), as well as a failing drive.

This is also safe to issue:

smartctl -l scterc /dev/sda
smartctl -l scterc /dev/sdb
cat /sys/block/sda/device/timeout
cat /sys/block/sdb/device/timeout
