Very cool info spider, thanks a lot!

More info to read through :) 
My current setup (with disks with multiple partitions belonging to
different raid arrays) helped to save my butt a couple of times when I
had filesystem or raid curruption.  Even though hde4 was bad, and
knocked out my md1 (and something in the filesystem messed up and nuked
it), I could still use md0 which had hde3 as part of it.  My concern is
going to a more sane seeming method of each disk having only one
partition for a raid array is that I'd lose this little extra barrier of
protection.  Of course, as others would say, "you don't run a system on
known bad harddrives" :)

One other question about the system set up (not so much the RAID setup)
is how to best configure partitions.  On my home system I have one drive
with hda1 being 10m for /boot, a small swap partition, and the rest for
/ and /usr and /var.  I guess having a big-ass 4disk RAID-N array (5 or
10 or 01 or whatever is best) created from disks partitions as such:

hda1 = 10m /boot
hda2 = 500m swap
hda3 = raid autodetect

hdb1 = 10m /boot mirror
hdb3 = 500m swap (striping swap is fun)
hdb3 = raid autodetect

and so on would be a sane setup?  It's a bit hokey looking to me
somehow, but I can't say why.  Maybe I should ask people to post their
production server with raid partitioning setups? :)  How is gentoo.org
partitioned and set up gentoo devs?
