If you've previously set up a RAID1 /boot (eg with older Fedora when it
worked fine or by hand)

If your /boot is RAID1 then you are ok only if your two volumes are
identically laid out so the map files are identical. At that point grub
is as ever utterly RAID unaware but whichever disk you look at you have a
valid copy of the data in the same place and it just works. It's also
possible to have two totally separate partitions one on each disk and set
each up as if it was a real /boot with its own grub install for the disk
etc.

You do then need to remember to copy over or rsync then one not mounted
at /boot (taking care to just rsync the kernels).

An existing failed /dev/sda or trying to set things up so it will
continue to work if /dev/sda fails ?
