Hi Jens, I've never bothered with actually making the boot device RAID as it's pretty easy to recreate if it dies. I do mirror my /boot partition on three drives so that hopefully I can change what BIOS looks at to boot and get the machine back up that way if necessary. I know of one person who reported that he made /boot RAID1 but only boots from one of the drive to automatically shadow changes he makes to /boot, but I've not tried that myself. As for /root, I'm using metadata=1.2 here, but it wasn't easy. It required an initramfs to figure out why it wasn't working, and then a _lot_ of care about RAID naming in both the physical RAID details as well as the mdadm.conf file to ensure it matched the eventual machine name. However it does work well for me. HTH, Mark
