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  
config:  
  
NAME STATE READ WRITE CKSUM  
tank ONLINE 0 0 0  
mirror-0 ONLINE 0 0 0  
disk1.eli ONLINE 0 0 0  
disk2.eli ONLINE 0 184 4  
  
errors: No known data errors

which also shows up in dmesg,

[76443.247801] zio pool=tank vdev=/dev/mapper/disk1.eli error=5 type=2 offset=2103171743744 size=53248 flags=1074267264

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