Thanks for reply, seem it is the -n option that give error.
I have successfully done a test transfer with minimum install, rsync to USB drive, new drives installed and rsync from usb drive to new drives.
It boot and all seems ok but did see following in /var.log/messages but this is not something to worry about?
