ZFS error vs smartctl, disk need to be replaced?
Hello,
I have ZFS running over LUKS encryption. ZFS out of a sudden started showing errors,
$zpool status
pool: tank
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using zpool clear or replace the device with zpool replace.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-9P
scan: scrub repaired 0B in 10:13:00 with 0 errors on Fri Nov 17 01:43:01 2023

tank ONLINE 0 0 0
mirror-0 ONLINE 0 0 0

disk2.eli ONLINE 0 184 4
errors: No known data errors
which also shows up in dmesg,

However smart 'long' test shows up ok. There doesnt seems to be any sector errors,
