Expanding a Perc5i Raid5

[Jefferson Cowart]

As far as booting from a GPT drive there are two options I'm aware of:

1. Grub2 - It has native support for GPT, so it should work, if you can
get it to compile/build/install/etc.
2. LILO - Since LILO doesn't actually read the partitions or
filesystems, it doesn't really care what the on disk format is. LILO 1st
stage just reads a block number to get the second stage. It does the
same for loading the actual kernel. While you will need to use a
standard partition near the front of the disk, this option can work
around the issues with GPT.

(Note: A colleague of mine ran into this problem. He and I spent a few
minutes talking about it, although I haven't actually had to deal with
it myself. He ended up using the second option since he couldn't get
grub2 to install.)
