I have a drive that just failed, well it did fail " offline uncorrectable returned to normal value". Either way i am replacing it as i have a read error when it was uncorrectable. I did a parity check 4 days ago. If i take the array offline right now throw a new drive in ad rebuild from parity will that error follow the rebuild?

Depends on what you mean by the error, if it was a read error on that disk during a normal read, no it won't be present on the rebuilt disk, assuming parity was in sync before that.

Yeah i received a notification of 2 read errors.  and parity was in sync before all of this. I have a drive ready to replace it when i get home. I have already used a VPN and shutdown the array which will hopefully stop anything else from happening.

The only risk here would be doing a correcting parity check with a bad disk, sometimes, and just sometimes, parity can be incorrectly updated if a disks fails during a correcting check.

Good to know. When running i was running parity i did not receive any notifications of errors. Thank you very much sir.
