I have pretty much rebuilt the servers usb fresh, i have a problem remaining, i imported the disks in the original order, selected parity is already valid and entered key. Great all works
reboot, unraid loads and start array button shows.
problem is it no longer asks for the key and just offers to format
temporary solution found : new config and map disks again and it works
i have have access to my old config folder from the corrupt backup/usb.
Can anyone help?
