software raid.

[David Dudek]

Disk druid actually makes it pretty easy.  First, partition your drives.
Keep in mind the following:

1. Your /boot partition should be a primary partition, and cannot be on a
   software raid.

2. Don't bother putting a swap partition on a software raid.  Putting two
   swap partitions each on separate drives gives you the speed benefit
   you're looking for without the overhead.  (I don't even think the newer
   versions of Disk Druid let you do that anymore anyhow.)

3. If you are going to attempt RAID 1 (mirroring), don't bother unless you
   have a hot spare that is partitioned indentically.  Actually, don't
   bother doing software RAID 1 with IDE drives unless you have a third
   drive that the OS, boot partition and swap are all on so that the
   RAIDed drives don't have to be partitioned.

When you set up the partitions, there is a file system type (ex: swap,
ext3, etc.) that is called "Software RAID" or something to that effect.
You need to make identically sized partitions of this type on each of your
drives.  After you have all your partitions, click on "Make RAID".  Select
the software RAID partitions that you made, and then select the RAID type
(I recommend 0 for what you are doing).  In the partition table display in
Disk Druid, the two software RAID partitons will be replaced with a single
RAID partition.  Select it and make its filesystem ext3 and give it a
mount point.  (/, /home, etc.)

I hope this helps.
