In my other RAID1s I've had /boot in the RAID. Actually, there was no separate /boot partition, it was just in / and that seemed to work. Now that I have a larger HDD, > 2TB, and I have to use GPT instead of DOS, I've had to make /boot partitions on both physical drives in the RAID1, but the two /boot partitions are not in the RAID. When I had Ubuntu install grub, it installed it on both /dev/sda and /dev/sdb, which is where the two /boot partitions are found. The thing that concerns me is that I don't see /boot if I run df, and I'm not sure how kernel upgrades will be handled. Will they go to the hidden /boot partitions on both /dev/sda and /dev/sdb? Ubuntu was clearly aware of them and I told the install that I wanted to be able to boot even with a degraded drive, so it was supposed to install the boot loader on both physical drives (and it seemed to do that). What do you think? Thanks again for answering so many of my questions! Mike
