May I ask a detail? Did you have to mark any partitions 'bootable'? Actually, did you have to mark bootable partitions on either or both disks in the RAID-1 pair? Or did you have to set any other partition 'flags'?
At very least, you'll also need to reinstall GRUB on the RAID1
Happy with that; I seem to have spent half my life reconfiguring Grub
and rebuild initrd.
But that's more serious. Thanks for the detailed comments. Ron
