Well it's been almost a year since I tried to set up
a simple raid1 workstation. (I.E. 2 identical drives,
boo/root/swap only with Raid 1). So I'm starting over.
I found this link:
http://en.gentoo-wiki.com/wiki/RAID/Software
Is this the best document to follow?
(note, I'm going to try to avoid using LVM:
fdisk -l

Disk /dev/md127 doesn't contain a valid partition table
<snip many more /dev/md### partitions.
So the drives are setup identical, and are identical 2T seagate
drivers. The md### partitions are all screwed up. So I think
I should just nuke all the data and start over, just keeping
the formatting.

parted shows the drives as set up fine (???), I just need to
erase each partition from here? Suggestions?
