sentein Posted January 6, 2020 Share Posted January 6, 2020 (edited) 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? Edited January 6, 2020 by sentein Quote Link to comment

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.

sentein Posted January 6, 2020 Author Share Posted January 6, 2020 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. Quote Link to comment
JorgeB Posted January 6, 2020 Share Posted January 6, 2020 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. Quote Link to comment
sentein Posted January 6, 2020 Author Share Posted January 6, 2020 Good to know. When running i was running parity i did not receive any notifications of errors. Thank you very much sir. Quote Link to comment
