Replacing a disk but failed

[Singman]

[ my previous thread is here : https://www.ixsystems.com/community/threads/failing-disk-and-lost-to-zfs-config.80686/ ]
Ok, I received a new disk to replace the failing one, so before removing it, I tried to putting it OFFLINE. No way, errors preventing that. So, I rebooted my NAS, tried again and was successfull.
Now, powering the NAS again, inserting the new disk, and in the UI, choosing REPLACE on the old disk and selected the new disk.
After 3 days of resilvering, I got that :

Code:

root@nas[~]# zpool status
  pool: Pool_1
state: DEGRADED
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

UI on Storage / Disk telling me my disk (ada2) have pool : unused
That's not what I was expecting :)

Can you help me ?

As indicated in your previous thread, you can't rebuild an array that has no redundancy. You will need to recreate the pool which will destroy the data on the existing disks during the reformat.

It looks to me like you're trying to replace a disk that has failed in a vdev with lost data, due to no initial redundancy. You have data lost with no redundancy. You need to physically replace the bad disk and recreate the pool from scratch, then restore data from backup.
