Grub doesn't support LVM RAID1 (it supports only RAID 4/5/6 type IIRC).
However, I don't recommend using /boot on LVM at the moment since
grub support for LVM is limited and unofficial. There's a plan to add
official and more robust support though - there are ongoing discussions
between grub and LVM team...

Hello !
May I chime in on this ?
If the raid1 is made OUTSIDE lvm (ie soft raid1 giving /dev/md0 as a PV for LVM) will the Grub be apt to find it and boot ?
Or is it the same case as above ?
Thanks.
