B_ISC Posted December 16, 2023 Share Posted December 16, 2023 (edited) Scratching my head on this one...unraid fluke? Dual parity 12TB, 6.12.6, all XFS drives, monthly checks, 0 errors on last parity check. 1. I precleared a 5TB that I've had as a hot spare for my array, 0 errors, shows in unassigned devices. 2. Removed Smart Failed/But Still Good 4TB from array (10 Uncorrectables) 3. Replaced With Pre-cleared 5TB 4. Started array with Rebuild, 0 Errors on rebuild 5. Red X a different 5TB drive!? ****The drive does have several uncorrectables**** Will a drive red X and emulate if it has too many uncorrectables? And not show any errors in the rebuild?

And not show any errors in the rebuild? since you have dual parity the system will be able to successfully handle 2 'failed/disabled' drives - the one being rebuilt and the one with a new red 'x' although you are not protected against another drive having problems until the current rebuild completes.

B_ISC Posted December 17, 2023 Author Share Posted December 17, 2023 But will a drive be flagged/emulated by unraid (Red X) because of too many uncorrectables? Or does there have to be something else wrong with the drive? Quote Link to comment
