Resilvering finished but Pool is broken

[Singman]

Hi,
I changed a disk, following the official documentation, but the result is not what I could expect (have already changed many times others disks) :

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.
   see: http://illumos.org/msg/ZFS-8000-8A
  scan: resilvered 947G in 0 days 10:58:09 with 3 errors on Sat Sep  5 08:07:04 2020

errors: 1 data errors, use '-v' for a list

How can I fix that ?

More Details please.
4HDD in RaidZ2 configuration?
Encrypted Pool or not?
Do you have a Backup and is the pool in general at the moment accessible?
What do the SMART-Data say for each disk? smartctl -a /dev/ADD YOUR DEVICE NUMBER, WHICH YOU GET FROM DISK LIST (most cases da1,da2 etc.)

- yes, 4x 2Tb HDD in RAIDZ2 (4 Tb capacity)
- not encrypted
- no backup (it's a media server), I can access it with no problem, just slowish
- Smartctl show absolutly no errors at all on all the disk, all of them are nearly new (less than 2 month old). I think I have a problem with a bad SATA cable on ada2, I will replace it when I have a solution for this pool's problem.
Another information :

1. Backup your data before doing ANYTHING else
2. No smart-errors is a good sign (and no SMR drive as well)
3. Yes, replace the cable and try another resilvering of the drive (maybe format it in another machine at first)

The good is, that you have one shot more, especially without encrypted pool, but anyway i would first backup the data and then start another resilvering process. Looks good so far, in worst case i would assume another HDD failure of the replaced drive.
