I am glad I asked! Thanks for all the info. Now my question next is if I am creating a 3 disk raid with a 1 disk spare, do I need to use any special 'mdadm' parameters besides what u see below for /boot (Grub)? # mdadm --create /dev/md0 --level=1 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1 --spare-devices=1 /dev/sdd1 Anything else I should add to the above command for my /boot partition?
Having a spare on raid-1 is fairly pointless, it hurts performance and buys you nothing. Having one more copy of the data built and ready serves you better.
