JorgeB Posted June 7, 2023 Share Posted June 7, 2023 Diags are after rebooting so we can't see what happened, you can try force enable disk3 but it will only work if parity is still valid: -Tools -> New Config -> Retain current configuration: All -> Apply -Check all assignments and assign any missing disk(s) if needed -IMPORTANT - Check both "parity is already valid" and "maintenance mode" and start the array (note that the GUI will still show that data on parity disk(s) will be overwritten, this is normal as it doesn't account for the checkbox, but it won't be as long as it's checked) -Stop array -Unassign disk4 -Start array (in normal mode now), and post new diags.
