May 14, 20233 yr Community Expert Solution That will fail because you have the wrong device name if using the /dev/sd? Devices you have to add a 1 on the end to specify the partition. Using those device names will also invalidate parity so is not recommended. if instead do this from the GUI while the array is in Maintenance mode by clicking on the drive on the Main tab to access the check/repair functionality it will use the correct device name for you and will also maintain parity.
May 14, 20233 yr Author um... a big duh to me. Trying proper command now. I blame not enough coffee. Edited May 14, 20233 yr by lonebear
