I am not familiar with that type of drive but the error tends to indicate that it needs to be replaced. If it is under warranty, definitely
get it changed out by the manufacturer.

i have some issues with understanding the report because the server still see that the pull is HEALTHY

You can have a drive fault and the pool remains healthy because that is what ZFS is designed to do. The pool will only be degraded if a drive is fully offline or is giving data errors. This health report from the drive is indicating that the drive has lost some capability but the drive is probably not giving any data errors yet.

I am not familiar with that type of drive but the error tends to indicate that it needs to be r.

here is a link for the model

ok, ill replace it, just to check if i am doing it right(cause it is first)
1. deactivate drive,
2. replace
3. add drive back to pull ?

update, drive is replaced with new one, and error is gone,, thanks

 

[Chris Moore]

I appreciate the link.
Happy it's working now.
If the drive is under warranty, I would send it back for replacement.
