and while you're at it setup your discs so you have 2 complete and distinct installations simultaneously. that way the next time around you can install the next before/without overwriting what's working.<br>

I have no idea how to do that.<span class=""><br>

i have 2 discs and build raid1 sets by setting the 2 discs up with identical partitions, on each disc i put two 300mb boot partitions, two 10gig swap partitions, and the rest of the space equally divided between two lvm partitions.<br>

I wouldn't know how to do that, either.<br>

Suppose I have two 3 TB disks, sda and sdb and I just want RAID1 with 300 MB /boot, 32 GB swap and the rest in /.
