This may not be directly useful to you.

As a general strategy, I have been thinking of making / and other important
partitions (if any) raid1 at system install - even when there is no second
disk. Someone just wrote that even the /boot partition can be raid1.

This way it will be easy later to clone the disk. Just bring in a blank
disk, format, add to the raid array and let it sync. :-) Then you would
still have to install grub, if the disk needs be bootable, but that's fast.
