In addition,  the wiki says " you will need to configure your distro to use an initramfs.

here are the last few lines of my grub.cnf:

         echo    'Loading Linux 4.4.0-36-generic ...'
         linux    /vmlinuz-4.4.0-36-generic root=UUID=cddffa50-9713-4205-aab6-86745735958b ro recovery nomodeset
         echo    'Loading initial ramdisk ...'
         initrd   /initrd.img-4.4.0-36-generic

should I be concerned my grub.cnf uses initrd.img and not initramfs?   My grub.cnf was last modified 11/2016 and I've rebooted successfully into a RAID1 since.

I think your problem is right there !!!

Look at the wiki, but I can NOT see the magic command "domdadm", without
which mdadm doesn't get loaded and the array doesn't get assembled. No
array, no root, no system ...

not really because subject is "GRUB warning after replacing disk drive in RAID1" and so mdadm is running and the array assembled

(Oh - initrd, initramfs, they're probably the same thing. :-)

yes
